Edward Powys Mathers's (1892 - 1939) introduced the cryptic crossword to Britain in 1924 through the pages of the Observer. Known as Torquemada, he was acknowledged as a brilliant translator and a critic specialising in crime fiction. In 1934 he published a selection of his puzzles under the title The Torquemada Puzzle Book - the final 100 pages of which contained the novel-cum-puzzle Cain's Jawbone.
