This volume brings together two series of short fiction by the poet, writer and religious philosopher Aleister Crowley (1875-1947). It includes the first complete publication of Simple Simon, the detective series featuring Crowley's most memorable fictional creation, the mystic-magician-philosopher-psychoanalyst-detective Simon Iff. The idealised Crowley in old age, Simon Iff is wise, knowing and unfailingly humorous as he applied psychoanalysis, Taoism and his own religious philosophy of Thelema to divine the depths of human nature and solve a wide array of crimes and mysteries. The six Scrutinies of Simon Iffstories are set in France and England, anchored by Iff's beloved Hemlock Club. The twelve Simon Iff in Americastories afford Crowley's penetrating insights into America as he found it during his residence from 1914 to 1919. His three Simon Iff Abroadstories take the reader to tribal North Africa, inaccessible Central Africa and to the high seas. The two Simon Iff Psychoanalyststories were among the earliest tales to use the new science of psychoanalysis to solve mysteries. Also included is Crowley's other major short fiction series, the eight stories of his legendary Golden Twigs, which were inspired by Sir J.G. Frazer's encyclopedic study of myth and religion in history, The Golden Bough.
