Cain’s Jawbone is a notoriously difficult literary puzzle and murder mystery written by Edward Powys Mathers (under the pseudonym Torquemada) in 1934. It is widely considered one of the hardest puzzles ever created. Here is a breakdown of why this book has a cult-like following: The Premise The Goal: There are 100 pages, six victims, and six murderers. Your task is to identify the killers and their victims. The Catch: The pages are printed in a completely random, haphazard order. To solve the mystery, you must first determine the one and only correct sequence of the 100 pages. The Difficulty: With 100 pages, there are (100 factorial) possible combinations-a number so large it’s practically infinite. Why it’s “Fiendishly Difficult” Cryptic Writing: Mathers was a famous cryptic crossword compiler. The text is packed with obscure literary references, puns, spoonerisms, and historical allusions that require deep research to decode. Extremely Few Solvers: Since its release in the 1930s, only a handful of people are confirmed to have solved it without help. Modern Resurgence: The book went viral on social media (specifically TikTok) a few years ago, leading to a massive new wave of people attempting to crack the code using “murder walls, ” spreadsheets, and deep-dive research. Quick Facts Author: Edward Powys Mathers (“Torquemada”) First Published: 1934 (as part of The Torquemada Puzzle Book) Format: The deluxe box set comes with the pages as individual cards, allowing you to physically rearrange them as you work through the logic.
