Six murders. One hundred pages. Millions of possible combinations... but only one order is correct. Can you solve Torquemada's murderous novel? In 1934, the Observer's compiler of cryptic puzzles, Edward Powys Mathers (aka Torquemada), published a book that was both a crime novel and the most difficult literary puzzle ever written. The pages of the book were printed completely randomly, but – through reasoning and careful reading – it is possible to arrange them in one correct order to reveal the six murder victims and their killers. So far, only a few puzzle enthusiasts have been able to solve the mystery of Cain's Jawbone: Do you have what it takes to become one of them? NUMBER OF PAGES: 216
