How real is Sherlock Holmes, and what is the nature of his reality? On the one hand, Holmes is a fictional character from writer Sir Arthur Conan Doyle, but on the other there is a Canon of 56 short stories and four novels defining that character. It’s hard to deny at least some reality to something so well defined.
Others have extended the concept of Holmes far beyond the original in books, movies, TV shows, and more. The original texts are in the public domain, so there is considerable freedom to explore the idea of a crime-solving duo comprised of a brainy detective plus a faithful sidekick.
As a result Holmes has a well-defined center and very fuzzy boundaries!

Among my second tier interests are murder mysteries, detective stories, and cryptography. The first typically includes the second, but there are many detective stories that don’t involve murder. Two of my favorite detectives, Spenser (by Robert B. Parker) and V.I. Warshawski (by Sara Paretsky), often have cases not involving murder.
The third interest I listed, cryptography, doesn’t usually coincide with the first two, but it did play a role in a recent locked-room murder mystery involving the delightful amateur detective Lord Peter Wimsey (by Dorothy L. Sayers). While I’ve always enjoyed secret codes, I’d never heard of the cipher Sayers used — the Playfair cipher.
It dates back to 1854, and is kind of cool, so I thought I’d share it.
