To my eyes, Sir Arthur Conan Doyle left two quite distinct legacies. The first, of course, was Sherlock Holmes, his searingly-flawed-but-unstoppably-insightful detective, whose long shadow still hangs over the entire detective fiction genre, 130+ years after A Study in Scarlet.

Yet the second was Conan Doyle’s literary conceit that one can combine wide-ranging observation with pure deduction (as opposed to merely providing a convincing scenario) so powerfully that it can completely reconstruct precisely what happened in cases of murder – which (with all legal caveats for accuracy) would need to be “beyond reasonable doubt”.

The first is fair enough, but the second… has a few issues, let’s say.

“Whatever Remains…”

“How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?” said Holmes in The Sign of Four, H&W’s second novel-sized outing. (Conan Doyle reprised the quote in the short stories The Adventure of the Beryl Coronet and The Adventure of the Blanched Soldier). Arguably one of the most famous Sherlock Holmes lines, this appeals not only to Holmes’ ultimate power of deduction, but also to his implicit omniscience.

Inevitably, this is precisely what the Rational Wiki’s Holmesian Fallacy web page skewers so gleefully, which itself is no more than a nice summary of numerous articles all arguing the same basic thing: that because Holmes could not possibly have conceived all the possible explanations that fitted a given case’s facts and observations, he could not have eliminated all the impossible ones.

Deduction by elimination is OK for maths problems (which are constrained by the walls of their strong logical structure), but it’s far from satisfactory for murder. My best understanding is that proof of murder is now far more often to do with demonstrating a direct forensic connection, i.e. proving a direct evidential connection between a victim’s death and the accused. Once this link is made, proving the precise details is arguably less important: that such a link has been made at all is normally enough to tell the lion’s share of a story beyond reasonable doubt.

All of which would be no more than a legalistic literary footnote for me, were it not the case that in (I would estimate) the majority of unsolved cipher theories, this kind of specious argument is wheeled out in support of the theorist’s headline claim.

Can we ever eliminate all the other possibilities in our search for the historical truth, thus rendering our preferred account the last Holmesian man standing? The answer is, of course, no: but in many ways, even attempting to do this is a misunderstanding of what historical research is all about.

Instead, once we have eliminated those (very few) hypotheses that we can prove to be genuinely impossible with the resources available to us, we then have to shift our focus onto constructing the best positive account we can. And we must accept that this will almost never be without competitors.

“The Curious Incident”

Gregory (Scotland Yard detective): “Is there any other point to which you would wish to draw my attention?”
Holmes: “To the curious incident of the dog in the night-time.”
Gregory: “The dog did nothing in the night-time.”
Holmes: “That was the curious incident.”

According to Holmes, “I had grasped the significance of the silence of the dog, for one true inference invariably suggests others….Obviously the midnight visitor was someone whom the dog knew well. It was Straker who removed Silver Blaze from his stall and led him out on to the moor.”

The “curious [non-]incident” (i.e. one that really should have happened but failed to occur) is, according to this legal blog, the piece of Holmesian reasoning most often cited in court. [e.g. “Appellate Court of Connecticut cited in its recent opinion in State v. Rosado, 2012 WL 1003763 (Conn.App. 2012), to answer a hearsay question.”]

In lots of ways, noticing the absence of something is a trick that requires not only keen observation, but also a curiously un-Holmesian empathy for the rhythms, cycles, and sequences of human life. There are forensic voids (e.g. where a removed body covered a blood spatter pattern, as just about any viewer of CSI would know), but behavioural voids? Not so easy.

The Somerton Man

All of which brings me round to Australia’s curious incident of the Somerton Man. What would Sherlock Holmes have made of a death scene riddled with so many voids, so many geese that failed to cackle, so many dingoes that didn’t howl?

Naturally, the biggest absence is the lack of any identity, followed by a lack of a definitive cause of death (though the coroner put it that the death was not natural [Feltus, Ch.10]), along with a lack of any preceding timeline for the man. Beyond these ‘macro-absences’, however, there are numerous micro-absences, all of which would surely have been grist to Holmes’ mental mill:

* Overcoat but no hat
* Tickets (one used, one unused) but no money
* No wallet
* No ration card
* Absence of dirt on his shoes
* Absence of vomit on his clothes or on the beach (despite blood in his stomach)

A particular suitcase (that had been left at Adelaide Railway Station on the morning before the man’s death) then appeared as potential evidence. Once it had been strongly linked with the dead man (thanks to cotton thread), it offered an additional set of absences to puzzle over:

* No shoes (apart from the pair he was wearing)
* He had five ties but no socks (apart from the pair he was wearing)
* Air mail blank letters and six pencils but no inkpen or ink, and no received letters
* Identifying marks (“Kean”, “Keane”, “T Keane”) that led the police investigation nowhere
* Places where Labels attached to a shirt and to the suitcase itself (?) had been removed
* No medicine of any sort (yet the dead man had a significantly enlarged spleen, so one might expect him to have been to a doctor or hospital not long before)

I’ve previously blogged about the “T Keane” marks, arguing that these might well have been donated to charity following the death of local man Tom Keane in January 1947: and separately that the slippers (which were the wrong size for the dead man’s feet) and dressing gown may have been given to him by the local Mission to Seamen (Mrs John Morison was probably the Mission’s hospital visitor). But this is a thread that is hard to sustain further.

I have also blogged about the Somerton Man’s lack of socks, something which vexed Somerton Man blogger Pete Bowes several years back in a (now long-removed) series of posts. I once tried to link these with the rifle stock mysteriously left by young Fred Pruszinski on the beach in a suitcase with lots of socks. Derek Abbott in particular has long been fascinated by what story the absence of socks may be trying to tell us, so perhaps there are more pipes to be smoked before this is resolved.

No Vomit, Sherlock

If this was a setup for a Conan Doyle short story, Sherlock Holmes would surely have pointed out that because the lividity on the dead man’s neck was inconsistent with his position laid on the beach (regardless of alternative explanations Derek Abbott might construct) and there was no vomit at the scene, he most certainly did not die there. And while the absence of a wallet would normally line up with a robbery, the body’s was clearly not so much dumped on the beach as posed, cigarette carefully put in place.

All of which Holmes would no doubt class as wholly inconsistent with any suggestion that the person or persons who did that was/were random muggers. Rather, this was a person who died elsewhere (and who Holmes would perhaps speculate had been laid out horizontally on a small bed post mortem, with his head lolling backwards over the edge), and whose wallet and money (and indeed hat, it would seem) were all removed before being carried to the beach [Gerry Feltus’ “Final Twist” has an eye-witness to a man being carried onto the beach, Ch. 14].

Holmes’ next waypost would be the absence of dirt on the man’s shiny brown shoes: having left his shoe polish in his suitcase, he would surely have been unable to shine his shoes in the time between the morning and his death in the night. And so I think Holmes would triumphantly complete the story told by the lack of vomit: that in his convulsions prior to death, the dead man’s vomit had surely fallen on his hat and shoes, and that someone else – dare I say a woman, Watson? – had cleaned the shoes prior to the man’s being carried off to the beach for his final mise en scène. And though he had eaten a couple of hours before his death, there was no trace of his eating out (another behavioural void to account for): he must therefore have spent some time that evening in a house with a man and a woman, eating with one or both of them.

So: they must have known him, or else they would not have cleaned him up in the way they did: yet they must not have wanted to be linked to his death, for they attempted (unsuccessfully, it has to be said) to stage a mysterious-looking death scene for him, one that would have had no physical connection to them (a pursuit which they were more successful in).

Did those people place the “Tamam Shud” scrap of paper in his fob pocket, as part of their dramatica staging? Holmes would surely think not: whatever its relation to the Rubaiyat allegedly found in the car around that time was, that was surely a separate story entirely, one quite unknown to them. And the car would form the centrepiece of an entirely separate chapter to Conan Doyle’s short story, one perhaps enough to tempt him to draw it out into a novella-sized accoun.

“The Case of the Missing Socks”

Finally, what of the missing socks? Sherlock Holmes would, I think, have first pointed out a sock-related mystery not previously noted elswehere: that even though the dead man’s suitcase had two pairs of Jockey underpants (one clean, one used) it contained not only no socks but no dirty socks either. In what circumstances would a man have dirty underwear but no dirty socks?

Hence once you have followed all the preceding Holmesian logic through, the three pipe problem that remains is this: why would someone walk around Glenelg with a pair of dirty socks, and not leave them in their suitcase back in Adelaide? Or, rather, why would someone travel with three pairs of underwear but only a single pair of socks?

For Holmes, the idea that the dead man would have carried anything around in smelly socks would be nonsensical. So I think the only conclusion the great fictional detective could have come to – having eliminated all he considered impossible – was that the dead man had arrived in Adelaide with something wrapped up in his spare pairs of socks in his suitcase – i.e. that he had brought spare socks with him, but that he was temporarily using them for a different purpose. He had therefore been able to change his underwear that morning but not his socks (because they were being used): moreover, Holmes would have said while tapping his pipe ash out, because the man was expecting to change into his spare socks later, he was without any doubt expecting to deliver what was wrapped up those socks to its destination during that day, and in doing so retrieve his socks.

But Holmes, Watson would ask, what was he carrying in those socks? Rolls of money, perhaps?

At this, Holmes would shake his head: my dear Watson, he would reply, this was not a man of money – his suitcase contents tell stories of ordinary life, of difficult times. He could not have been carrying anything bulky, or people would have noticed: it must have therefore been something valuable on the black market yet carryable beneath an overcoat on a train, bus or tram – and if so, why wrap it in socks for any reason apart from disguising its iconic shape? Hence, having eliminating all the impossible – as I so often do – the only object it can have possibly been was… a rifle fore-end.

My goodness, Holmes, Watson would reply, I do believe you have astounded me yet again. Derek Abbott was right: I shall have to call this The Case of the Missing Socks when I write it up in years to come. And… what of Fred Pruszinski?

What of him indeed, Watson…

“Whatever Remains…” (revisited)

From my perspective, I can see how Holmesian reasoning can almost be made to work: and I would argue that in the otherwise baffling case of the Somerton Man, the kind of short story reasoning I lay out above is just about as connected a positive account as can be genuinely fitted to the evidence. Had the Somerton Man brought something into Adelaide wrapped in his spare socks, expecting to deliver it during the day? It’s a good yarn, for sure, one that could easily be shoehorned into the Holmes and Watson canon. And, moreover, The Case of the Missing Socks does justice to pretty much every aspect of the case, both found and absent.

And yet, a small amount of prodding around the edges would surely display its many cracks and holes: it all remains no more than a story. We lack evidence: and ultimately it is evidence that persuades, evidence that proves, evidence that convicts. Reasoning from that which isn’t there and from that which did not occur all the way to that which did happen is a perilous argumentative tight-rope, a place surely only well-paid QCs and conspiracy theorists would feel comfortable balancing on.

As for me, I’m only comfortable writing this all up under cover of a Sherlock Holmes-themes blog post: but right now, perhaps building on a long series of absences to assemble this kind of novelistic take is as good as we can get. :-/

UPDATED – TALK NOW CANCELLED (BY GOOGLE CAMPUS LONDON), VERY SORRY! 🙁

(This is a little off-topic, but what the hey.)

When I’m not trying to crack unbroken historical ciphers, my day job is as a software developer: and over the last few years, I’ve got more and more frustrated with the abysmally low productivity of the whole industry.

And so I’ve been putting a lot of thought into how to make things better. And by “better” I don’t mean a mere 10% better, but instead something closer to 10x better – for example, how to write a hundred lines of new code that does the work of a thousand lines of old code. But note that this really isn’t about Computer Scientists devising the ‘perfect’ programming language, it’s about looking at the different activities software developers do and seeing how we can turbo-charge them all, almost beyond recognition.

Back in 2015, I called this “The Ten Times Manifesto” to try to give it some shape and direction, and discussed it with a whole load of people.

Now in 2018, it’s time for me to take The Ten Times Manifesto out on the road, to open up lots of new conversations with lots of new people and see where the whole constellation of ideas leads. I genuinely think this is the time that software development has to make a step change, to turn itself from something creaky and barely adequate into something radical and new; and I think London is a great place to begin.

Hence my first Ten Times Manifesto gig is now cancelled provisionally booked for 6pm, 10th August 2018 at the well-known Google Campus London, 4-5 Bonhill Street, London EC2A 4BX, which has space for 135 people.

The description runs:

After a lifetime writing software (including classic retro 1980s games such as Frak! and Zalaga), Nick Pelling created the Ten Times Manifesto to try to answer the question: how can we software developers do all the things we do but 10x better and/or 10x faster?

Expect a lot of good ideas, a lot of interaction, a lot of gratuitous movie references, and to go home afterwards with a lot to think about.

Core audience: anyone who develops software and wants to do what they do 10x better. 😉

When tickets become available (very shortly), they’ll be free – so anyone who wants to come along should move fast. 😉 I hope to see 135 of you there!

As a quick reminder, we’re looking for historical evidence (a) of a brig sailing out of England (probably London) to Massachusetts (probably Boston) in late April 1738, and (b) of a proclamation that appeared in a London newspaper listing a reward for the capture of a 4-gun French privateer sloop called “The Eagle” or “L’Aigle”. There may also have been mention of the capture of the brig by the sloop in the Boston newspapers in mid-late May 1738.

I listed the Boston newspapers active in 1738 in a previous post: but what of London newspapers?

Lloyd’s List

Without any real doubt, Lloyds’s List would have listed almost all the ships leaving London for Massachusetts in April/May 1738: and would also very likely have mentioned any proclamation made by the King against a French pirate ship. Unfortunately for us, the earliest (according to the website of the MARINER-L mailing list) extant copy of the post-1735 Lloyd’s List series dates only to 1740/1741:

About mid-March 1735, the list was revised again, with publication changed to twice a week, on Tuesdays and Fridays, and new numbering. Of this series, the earliest surviving copy is dated 2 January 1740/41, and is numbered 560 [reproduced in McCusker, op. cit., pp. 324-325, Fig. 6A and 6B]

All the same, if you’d like to see these for yourself, Google has made available many digitized early copies.

The Penny London post

“The Penny London post, or, The morning advertiser” is listed at the LOC.

Here are the copies I’ve managed to find of it:

* Worldcat lists copies in the Burney collection from 1733-1734 and 1744-1751
* The University of Queensland has copies from 1744 to 1751, which are also available on microfilm from Research Publications, Inc.
* Copies from 1747-1749 are available behind the newspapers.com paywall here –
* The Harry Ransom Center at U of Texas at Austin has a couple from 1750-1751

So… unless there are separate copies of the Penny London post in other archives, it looks very much as though we’re out of luck for 1738, sorry. 🙁

The London Daily Post

The London Daily Post was another London newspaper active in 1738, and is listed at the LOC.

The British Library’s holdings are as follows:

The London Daily Post, and General Advertiser. no. 1-109, 111, 113, 115-119, 136, 203, 205, 207-210, 213, 219, 220, 223, 225, 227, 230, 231, 236, 238, 247-254, 259-677, 854, 1006, 1009-2244, 2558-2908.; 4 Nov. 1734-10 March 1735, 12, 14, 17-21 March-10 April. 27, 30 June, 2-5, 9, 16, 17, 21, 23, 25, 29, 30 July, 5, 7, 16-26 Aug., 1 Sept. 1735-31 Dec. 1736; 27 July 1737; 19, 23 Jan. 1738-31 Dec. 1741; 1 Jan.-10 March 1744.

This is my red-hot top tip for where to look!

Read’s Weekly Journal, or British Gazetteer

The British Library holds the following issues: 283-789, 1331, etc. 22 Aug. 1730-22 Dec. 1739; 3 March 1750-2 May 1761. So this too is a newspaper of the day that needs checking.

Other London newspapers of the time

The British Library also lists:

* The Universal London Morning Advertiser. London, 1743-1744
* Parker’s Penny Post. no. [1-]414. 28 April 1725?-29 Dec. 1727.

I also saw a brief mention of an unnamed Irish newspaper dating back to 1738, which might possibly be a additional source for North Atlantic shipping- and piracy-related news of the day.

Incidentally, webpages posted up by assidous historical newspaper raiders can often list numerous publications that rarely appear in formal lists of newspapers. For a good (if slightly startling) example, I can recommend The Rabbit Woman as collected by Rictor Norton from various obscure sources: and also an online bibliography of the Slave Trade, both of which I am now following through carefully.

Many Eagles

Just so you know, by 1744 there was an English privateer called Eagle sailing out of Dover (Captain Bazely): and in 1745, a new incarnation of HMS Eagle had also been launched. So please try not to get too excited about finding mentions of the Eagle in post-1738 newspapers. :-/

I’ve been carefully reading the diary entry scanned in from the Prince Edward Island Magazine by Matt Malone, and wondering if it might be possible to reconstruct the secret history yet further. We now have what seems likely to be a name for the person who constructed the cryptogram: while the account gives a number of pointers to specific pieces of historical evidence that could feasibly be tracked down. Hence I thought I’d post a list of possible research leads to follow.

J Crowshay?

What little I can see beyond ancestry.com’s paywall is that a James Crowshay (born 1715?, hence aged 23 in 1738) married a certain Margaret Seuton. This seems to have been in York (according to this Spanish Geneanet page).

Might this J Crowshay have been the same young man who was (according the diary account) a seaman on a brig (presumably sailing out of London) bound for the (then British colony of) Massachusetts in late April or early May 1738 that was accosted by the French sloop L’Aigle (The Eagle); and who was rewarded for his zeal in defending the brig against French pirates by being taken prisoner by them? “The ship escaped without serious injury”, but was most likely relieved of all its cargo (and the single fighty seaman taken prisoner).

The Attacked Brig?

If the account of the French seaman (who had returned to Prince Edward Island to dig up the treasure, but had found his memory wanting) is correct, the ship from which the young seaman was taken prisoner was a brig (only lightly armed merchant ship) on its way to Massachusetts, so probably sailing into Boston.

Might there have been a mention of this action in the Massachusetts press of late May 1738 not long after the brig presumably arrived there?

As far as I can see, there were six newspapers published in Massachusetts during 1738, all from Boston (none of which are in the LOC, while Harbottle Dorr Jr’s newspapers all start from 1765, while BGSU doesn’t list any from 1738 as being freely available on the Internet). GenealogyBank has copies from 1735 for name searches, but behind a paywall.

The newspapers I’d like to have a look at for May 1738 are as follows, two of which are listed on the Massachusetts Historical Society’s ABIGAIL database:
* Boston Evening-Post
* Boston Gazette
* Boston Weekly News-letter
* The Boston Weekly Post-boy (Massachusetts Historical Society: OFFSITE STORAGE SH 18R2 )
* The New England Weekly Journal (Massachusetts Historical Society: OFFSITE STORAGE SH 18XP Q (1733-1738) )

If anyone has shelfmarks in different archives for the other newspapers, please let me know, thanks!

Other newspapers may be listed in (1907) Check-list of Boston Newspapers, 1704-1780, which I haven’t yet consulted.

The Eagle or L’Aigle?

The diary account includes no names or details of the French pirate ship The Eagle (L’Aigle). However, the French seaman telling the story to the diarist relates that the young seaman taken prisoner had in his possession a newspaper account (published “in the city of London”) that detailed how the King (presumably of England) had made a proclamation offering several hundred pounds for the capture of The Eagle.

If this is correct, it should be possible to find a copy of this proclamation – it (and/or any copies of it in the London press) may well have additional information. However, all I have found so far for 1738 relates specifically to Spanish attacks on British shipping than with the French:

Alderman Perry, on the 3d of March [1738] brought into the house of commons a petition from the merchants, planters, and others, interested in the American trade, specifying these articles of complaint, which they recommended to the consideration of the house. This petition with others of a like nature, which produced warm debates, were referred to a committee of the whole house, and an order was made to admit the petitioners to be heard by themselves or by counsel. Sir John Barnard moved for an address to the king, that all the memorials and papers relating to the Spanish depredations, should be laid before the house, which with some alteration proposed by Sir Robert Walpole, was actually presented, and a favourable answer was returned.

This parliamentary debate appears in the History and Proceedings of the House of Commons Vol. 10. The King of England in 1738 was George II, for whose coronation Handel wrote “Zadok The Priest”: his response to the petition made no mention of the French:

Gentlemen,

I Am fully sensible of the many and unwarrantable Depredations committed by the Spaniards; and you may be assured, I will make use of the most proper and effectual Means, that are in my Power, to procure Justice and Satisfaction to my injured Subjects, and for the future Security of their Trade and Navigation. I can make no Doubt, but you will support me, with Chearfulness, in all such Measures, as, in Pursuance of your Advice, I may be necessitated to take, for the Honour of my Crown and Kingdoms, and the Rights of my People.”

Any good suggestions as to where to look next?

Thanks to help from Cipher Mysteries commenters Paul Relkin and Thomas, it became clear that though my initial attempt at cracking the Hollow River Cipher was close, it wasn’t as close as it could have been. Essentially, even though I worked out the upper case / lower case trick and what I thought was a single cipher, it turned out that there were actually two separate ciphers in play (i.e. for lower case letters in the cryptogram) that the encipherer could choose from, either a +1 Caesar Shift or a -2 Caesar Shift.

It then became acutely clear that the otherwise mysterious line “2 = 1. 1 = 3. A = A.” in the cryptogram was therefore the key to the cipher, where the two Hollow River Cipher alphabets are as follows:

a b c d e f g h i j k l m n o p q r s t u v w x y z
B C D E F G H I J K L M N O P Q R S T U V W X Y Z A  (+1 Caesar Shift)
X Z A B C D E F G H I J K L M N O P Q R S T U V W X  (-2 Caesar Shift)

This means that we can decrypt almost all of the cryptogram, leaving only a handful of letters ambiguous. Here are the workings out:

e q E m e g u k O O o k A I k E    [= cryptogram]
F R E N F H V L O O P L A I L E    [= +1 Caesar Shift if lower case]
C O E K C E S I O O M I A I I E    [= -2 Caesar Shift if lower case]
F R E N C H S L O O P L A I L E    [= Most likely plaintext]

This gives the following net decryption:

FRENCH SLOOP L’AI[G]LE
GULF ST LAWREN[C]E MAY 10, 1738
PRISONER GUARDED CREW ONSHORE
LEAGUE WEST NAUFRAGE
I. ???
MEN PLAN UNNOWN INTEND WRECK SHIP TOOK ALL GUNS AND TREASURE HIDDEN ? IN
FIVE EIGHTS ONE HUNDRED AND ELEVEN ??? UP SMALL
STREAM – LINE HALF LENGTH N. WEST FROM SOUTH END –
PITS MIDDLLE SECOND. J CROWSHAY.

If the “L’Aigle” was the French Sloop ‘Eagle’ mentioned in the diary entry, then I’m almost certain that the “FIVE EIGHTS” were five 8-pounder cannon boxes. Moreover, my best guess for the final ??? is that this is YDS (i.e. “ONE HUNDRED AND ELEVEN Y[AR]DS UP SMALL STREAM”).

Hence it seems that what we have managed to decrypt is indeed exactly the kind of treasure map every schoolboy since Treasure Island has fantasized about:

1) TOOK ALL GUNS AND TREASURE HIDDEN ? IN FIVE EIGHTS
2) ONE HUNDRED AND ELEVEN Y[AR]DS UP SMALL STREAM (i.e. the Hollow River)
3) LINE HALF LENGTH N[ORTH] WEST FROM SOUTH END
4) PITS MIDDLE SECOND
5) [Signed] J CROWSHAY

So, if you walk 111 yards up Hollow River, then follow a line roughly half that length (say, 55 yards) in a north-westerly direction from the south end, you might well find pits containing five eight-pounder cannon stuffed out with treasure. (The “Legend” specifically mentions five pits!)

Of course, I’d say that there’s a 90+% chance that this Hollow River Treasure has been cleared out or robbed out over the centuries (particularly given what was related in the “Legend” article), but you can never be 100% sure of what’s still there, eh? So… do we have any Cipher Mysteries readers on Prince Edward Island? (Asking is free, right? 🙂 )

Here, courtesy of Cipher Mysteries reader Matt Malone, is a new historical cipher that he calls the “Hollow River Cipher”, which he found in a magazine from the early 1900s called “The Prince Edward Island Magazine” while on vacation. (There are 67 issues scanned online here from 1899 to 1905, so other interesting stories may well be lurking there for the persistent.)

The first part of the story, related by Mr Senachie, was on pages 163-164 of the July 1900 edition:

This mentioned a pair of strange rectangular pits that appeared near the Hollow River around 1840 one March, that some thought might be to do with treasure pits.

A follow-on article by “D. A. W.” appeared on pages 241-248 of the October 1900 edition:

This related a story copied from “a remnant of a comprehensive diary”, dated 1749, that described a cryptogram dated 1738 that the diary writer had found written on folded parchment in a floating bottle, as well as a story of how some treasure was buried (allegedly in 1738) in similar size holes to the ones (presumably uncovered by the winter’s frost) found in 1840.

All the pages can be conveniently found on a single imgur webpage, courtesy of Matt Malone. Or, if you want to download all the pages in one go, Matt has very kindly placed a single zipfile here.

The Hollow River Cipher

Of course, we cipher people have long learnt not to put too much trust in the stories that end up backfilled around unsolved ciphers (e.g. the Beale Ciphers etc). Rather, we must instead start with the cryptogram itself as reproduced in the PEI Magazine:

Here’s my transcription of the cryptogram in the magazine:

e q E m e g u k O O o k A I k E              |    m u g O q E
i U k e u s k A y q E m E o A Y 10, 1738     |  k E A i M E y E u s m A U e q A i E
2 = 1.          1 = 3.        A = A.         |    I. u s i o
o q I u O m E q f U A q c E c e q e y O      |  g m o k A m w m m O y m I m s E mc y q

I s u o I c c k k E u E e O m c. i eq O y u g A Y.

My initial decryption notes:
1) the letters appears to have been spaced apart for clarity (which is nice)
2) the two panels of lines 1-4 appear to be intended to be read left-half then right-half
3) the top left of lines 1-2 is probably the place/date where/when the note was composed
4) the left half of line 3 appears to have a somewhat mysterious structure
5) some pairs of letters have no space between: mc (lines #4 and #6), eq (lines #6 and #7)
6) there are a few hyphens and a few full stops, almost all in the final two lines.
7) having been found off Canada, the plaintext language is probably French or English

Now, I could leave this for my readers to figure out (which is what Klaus Schmeh does with his messages found in bottles)… but many apologies, becauseI’ve basically cracked most of it already. So here’s what it (mostly) says:

Nick’s Decryption

Using the above transcription carefully, CryptoCrack was able to help move me far enough in the right direction to work out the basic idea behind this cryptogram. The big trick is that only lower case letters are enciphered, i.e. upper case letters are completely unenciphered (and these are usually vowels).

Once you’ve got that idea worked out, you then have to try to read past the inevitable enciphering errors and copying errors that cryptograms almost always include. (Here we have parchment -> diary -> copy of diary -> article passed to editors -> article typeset in magazine.)

Where a letter seems to have been omitted in the plaintext, I’ve inserted an underscore. A few letters have been manually corrected to the most probable, but it’s pretty much all as it should be:

IsuoIcckkEuEeOmc.ieqOyugAY
ITSMIDDLLESEFOND.GFROWSHAY

My best guess is that “GFROWSHAY” is the name of the English sailor writing this note, though there may well be errors in his name. 🙁 And might the “SMALL STREAM” be the Hollow River (which was indeed little more than a creek)?

Overall, here’s my attempt at reconstructing the enciphering table, though many of the cryptogram’s slips and miscopies have made it hard to be 100% certain:

a b c d e f g h i j k l m n o p q r s t u v w x y z
C - D - F Q H - G - L - N - M - R - T - S - U - W -

My best guess is that “2 = 1. 1 = 3. A = A.” is somehow an aide-memoire for the cipher table. But I don’t know exactly how.

But It’s Not All Over Yet…

Tantalizingly, the lines containing the phrase “ALL GUNS AND TREASURE HIDDEN” onward are extremely hard to make out. So now that I’ve got this started, this is where my talented readers come in, to try to resolve all the genuinely difficult stuff that I’m unable to.

What can you clever people make of the rest of this? Does it describe where to find treasure? 🙂

In 1992, the American Congress ruled that all documents related to President Kennedy’s death should be released within 25 years: and when President Trump raised no objection last October, that is essentially what happened. Except, of course, that there were still numerous redactions. (Did you really believe it would be otherwise? *sigh*)

Arguably one of the most interesting set of documents released has a specifically crypto angle. Flight Sergeant David F. Christensen claimed that in the run up to Kennedy’s death, he had intercepted an encrypted communication between certain individuals in the Cuban Government and an individual well known in the organized crime world, plotting the assassination. His attempts to get the intercept to NSA were thwarted, causing him (he claimed) to have a mental breakdown, a divorce, etc etc.

Conversely, others say that this never happened; that searches of the files revealed nothing (“recognizing that most records from this period no longer exist“); that Christensen suffered from alcoholism and family problems, etc etc.

I can’t judge either way: but I thought it would be good (a) to include links to the various NSA scans and (b) to properly transcribe the letter Christensen wrote. Which is what I did here. 🙂

Mr. Blakey stated that he did not know who the crime figure is: Christensen’s
supervisor, Sgt Praeter (actually “Prater”) refused to send this
traffic to NSA and this, he alleges, eventually caused him to have
a mental breakdown.

David F. Christensen
V.A. Hospital
Sheridan, WY 82801

Nick,

Well after 13 1/ 2 years I finally found out your whereabouts. Dam, its
been a long time since Kirknewton, Scotland, and the beer we drank on the
beach and the club. Had to get your address from the outfit in Texas.

Nick, whatever happened to Sgt Prater. If you know his whereabouts please.
send me his address. How in the hell have you been doing?

Nick, I had a nervous breakdown. Plus in 74 my leg shattered in over a
hundred places. Things have really gone to hell for me. I’m working with
the vets benefits counseler, who is a ex 203. Speaking of 203’s where the hell
is Frenchy? You know the little guy. What I’m going to say is no longer
classified, so don’t get all shit shook. I’ve done checked it out.

Christ, you remember the position I worked at, in Sgt Praters section, don’t
you? You remember about a month or 6 weeks before I left Scotland, when I picked
up a link mentioning the assassination of President Kennedy. How hard I tried
to get it sent out, and because of that fuckin Forney and Delaughter they wouldn’t
send it to NSA. Since I have learned that the man’s name; most mentioned was
number 4 in a certain branch of organized crime at the time. Was number 2 last
year. I will send you a form for proof of claim. This guy here “the 203” says
I should be getting a service connected disability for my nerves. The “link was”
Lisbon to Tangiers you remember. How I got my ass chewed for not dropping the
link. Have learned that this branch of crime often will put out a feeler of
forthcoming things. By sending it as a practice message.

Nick it really broke me up after Nov. 22, 63. Especially when I had it all
before hand. It was first like the 202’s said, Ha. I was nuts when the Russians
first came out with the ITI & B’s. Later proved them wrong didn’t I. That was
another first for us as I recall. Duane Bruntz from Baker trick put up a good
support of my claim. I’m sending you this certified so to make sure you get it.
As I recall you should be able to B.S. them good enough to help me. I know it
cost me a divorce and every thing from my wife. Christ, you remember Marlene,
don’t you? That good looking little 1/2 Indian girl from N. Dak. Nick when
you get this form send it back to me and I’ll let the vets benefit guy to send
it in. Being a M.Sgt I think you know how to bull shit pretty good . Also do
you know Sgt Harley and Sgt Willy Hendrickson’s address. I guess old Garnett K.
Tatum
retired. Wonder what gehto, he is living in, Ha!

What in the hell are you doing in Florida, any how? Be sure to put
emphasis on my nerves going to hell and not giving a shit about my work after
the interception of the message.

Y Y Prosign

Your old buddy from the Berkely Bar

Suggestions for filling in the redacted gaps (and there are certainly many gaps here) will be gratefully received, thanks!

As to the “Prosign” line (Prosigns were groups of Morse code letters run together without any pauses between them), I know that VY = very, YF = wife, YL = young lady, but what does YY mean?

What happened to David F. Christensen?

Apart from knowing (from his letter) that he married Marlene from North Dakota and was in a V.A. Hospital in Sheridan WY, I have little biographical information on David Frederick Christensen. The only grave I found for that name was in Arlington National Cemetery for an infant (born 22 Nov 1957, died 23 Nov 1957, son of O. E. Christensen), and who was therefore not the same person at all.

Perhaps Cipher Mysteries readers with access to proper databases will be able to find out more about former USAF Flight Sergeant David F. Christensen, who was listed here as working at the USAF listening station at RAF Kirknewton in Scotland. As normal, feel free to leave comments below. 🙂

*** UPDATE ***

Here is a link to an online memorial to David Frederick Christensen (he died in 2008):

David passed away Monday, December 22, 2008 at his home in Killdeer, ND. David Frederick Christensen was born January 26, 1942 to Ole and Hazel (Lodnell) Christensen in Dickinson, ND. He grew up on a ranch near Halliday and attended schools, graduating from Halliday High School in 1960. David and Marlene Burr were married in 1960 and to this union two sons were born, Michael and David. David enlisted in the US Air Force and served with the Radio Intelligence in the Scotland Unit. He was honorably discharged in 1963. He then returned to the home ranch in the Halliday area. David began working in the oilfields, which took him to various places in the western United States. He enjoyed rodeos, playing pinochle and time spent with his family. David is survived by his two sons; Michael (Bobbie) Christensen, Rapid City, SD and David (Georgette) Christensen, Apple Valley, MN; a first cousin, Patricia (Pat)( Phil) Braeger, Watertown, SD; six grandchildren, Haley Christensen, Tyler Christensen, Jordan Christensen, Justin Christensen, Benjamin Christensen and Kendra Christensen. He is preceded in death by both parents.

An open question to the house, really: even though I have all manner of books and papers relating to other cipher mysteries, it struck me as odd a few days ago that I have next to nothing on the Zodiac Killer that I’d consider any sort of capsule library on the subject.

Despite his love of Americana, the section on the Zodiac Killer in Craig Bauer’s Unsolved is no more than a starting point (and that whole strand didn’t really end too well, in my cryptological opinion).

Conversely, I’m not sure I have enough pinches of salt to consume Robert Graysmith’s meisterwerken on the subject. Or is that just par for the whole Crazy Golf course, a necessary initiation of pain so you have been through the same awfulness as everyone else?

What I want is a Zodiac Killer book that sensibly describes each of the confirmed murders, the messages he definitely sent and all of the extant evidence (e.g. stamps, hairs, saliva, fingerprints, palmprints, DNA): and also discusses the murders that Zodiac claimed but didn’t carry out himself, and the messages attributed to him but which very probably weren’t by him.

But is this just too dreamily rational and sensible to hope for?

The logic is ineluctably Vulcan: unsolved historical ciphers are cool… novelists like to lard their books with cool stuff… ergo here’s yet another cipher mystery novel to review.

The book’s author, Jess Lourey, is a Sociology/English professor: and if I told you that she also lectures in creative writing, you may have a good idea of where this is going.

Firstly, the bad stuff: anyone who doesn’t like the sound of reading all-italics flashback chapters telling how the two main young women protagonists shared ice cream and cookies and tried different hair styles when they were growing up together probably isn’t going to be able to last to the end of the book. I certainly had to grit my teeth fairly hard to get through some of these. These bits were more chick than lit, let’s say.

Also, anyone who finds it difficult to buy in to novels where the main characters are stalked across the country by spectacularly sadistic and implausible assassins (say, like The Da Vinci Code) may find their copy of the book involuntarily sailing across the room at some point (personally, I found page 79 quite challenging in this respect).

The good news is that Lourey has done a fair bit of cipher mystery lurking and looking, and presents the Beale Ciphers reasonably accurately (I doubt I’d be spoiling anyone’s read if I said that various of the protagonists make their way to a well-known vault in Virginia).

Overall, though, the plot plays out like an all-female National Treasure remake, complete with national monuments, suitably appropriated historical figures, and more hidden compartments than you can shake Nic Cage’s torso at (there’s even Alcatraz in there for Cage completists). Though rather than Science vs Religion or Black vs White or Blue vs Red or even Humans vs Insects (Philip K. Dick short story reference), Lourey pitches Evil Rich Men vs Idealistic Poor Women as her two Conspiratorial axes. Which is nice.

Cryptologically, Salem’s Cipher itself (one of the protagonists is called Salem) appears at the start, where Salem figures out a way of using Charles Babbage’s work to power quantum cryptology. But this promptly disappears, making it not so much a Chekhovian gun as a Checkhovian RPG. But perhaps it will reappear in Book 3. (Book 2 is set in Europe, but hopefully will manage not to reprise Garfield 2.)

Is Salem’s Cipher worth reading? To me, it feels like a slightly awkward cross-over, a chick lit feminists-save-the-world spin on the clunky mainstream crumb-trail cipher mystery Americana chase thriller genre: and if that description doesn’t put you off, you should probably get yourself a copy ASAP. 🙂
