Postcard box: Cain's Jawbone: A Novel Problem

Six murders. One hundred pages. Millions of possible combinations… but only one is correct. Can you solve Torquemada’s murder mystery?

In 1934, the Observer’s cryptic crossword compiler, Edward Powys Mathers (aka Torquemada), released a novel that was simultaneously a murder mystery and the most fiendishly difficult literary puzzle ever written.

The pages have been printed in an entirely haphazard order, but it is possible – through logic and intelligent reading – to sort the pages into the only correct order, revealing six murder victims and their respective murderers.

Dare you take it on?

Please note: this puzzle is extremely difficult and not for the faint-hearted.
