It’s one of those strange stories that sounds oddly romantic at first, then somewhat confusing, before ultimately ending up sad. The tale of Nora Emily (‘Netta’) Fornario’s curious death on Iona in November 1929 was recently picked up by Mental Floss (which is where I first heard of it), and if you just want to … Read More → The post Netta Fornario’s missing papers… appeared first on Cipher Mysteries.

I’m cautiously optimistic that a breakthrough has just emerged to do with the Art History origins of the Voynich Manuscript’s puzzling zodiac pages, that would appear to connect them with Diebold Lauber’s fifteenth century manuscript copying house.

Lots of fragments of research into the Hollow River Cipher to pass your way.

An excellent article by Berthold Hub (though in Spanish) on Antonio Averlino’s Sforzinda appeared not long ago, where Hub attempted to trace through many of the ideas / preceding documents that fed into Averlino’s libro architettonico.

A few days ago, Cipher Mysteries commenter Paul Relkin very kindly sent me through a copy of a document listing James Crowshay’s marriage to Margaret Seaton in 1745: This inspired me to hunt for more information, mainly via the LDS’s (frankly astonishing) familysearch.org website.

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 … Read More → The post Sherlock Holmes, the Somerton Man, and the Case of the Missing Socks… appeared ....

(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.

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”. … Read More → The post 1738 London newspapers… appeared first on Cipher Mysteries.

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.

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.

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.

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.

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.

To summarize, we have a 1716 treasure map from Philadelphia that leads to a particular small brick building in Cherry Garden, leading downwards from the southeastern corner of Society Hill to the Delaware River.

I’ve written before about Grove Words and what they might be, and also about the curious patterns that occur at the start of lines.
