Cain's Jawbone

Cain's Jawbone is a 100-page murder mystery puzzle published in 1934 by Edward Powys Mathers under his pseudonym Torquemada. The pages are presented in random order, requiring readers to determine the correct sequence while identifying six murders and their perpetrators. The text contains literary references, wordplay, and cryptic clues embedded within its narrative structure. The mathematical possibilities for page arrangements exceed 100 factorial, yet only one sequence reveals the true solution, which remains unpublished to this day. The puzzle achieved renewed attention with a 2019 reprint by Unbound publishers, presented as individual cards rather than bound pages. Only three people have solved it since its original publication - two winning prize money in 1935, and one receiving written congratulations from the author. At its core, the work explores connections between language, logic, and narrative through its innovative format and multilayered complexity. The biblical reference in its title points to themes of violence and mortality that run throughout the text.
