Spy Novels and Cryptanalysis: A Literary Look at Sigint

This article explores the portrayal of cryptanalysis in spy fiction. The author argues that directly describing the cryptanalytic process is difficult to make engaging for readers; successful works focus on characters and plot, not technical details. Using John Buchan and Dorothy L. Sayers as examples, the author analyzes how they cleverly handle cryptanalytic subplots. The article also mentions a few other British novels that touch on intelligence agencies and cryptography, notably recommending Michael Frayn's *The Tin Men* as a satirical take on GCHQ and a pioneering work on AI.
