Over half a million copies sold

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.
