At last, the unexpurgated, true story of the amazing Aleister Crowley--philosopher, poet, artists, writer, magus, explorer, parapsychology--and spy. Packed with fresh research and previously unpublished 'Crowleyana.'   For 100 years, Aleister Crowley's true achievements have been suppressed and his true character defaced in a campaign of vilification unparalleled in British history. Until now, Crowley's life has not been written--it has been written over.   Tobias Churton is a world authority on Freemasonry, Rosicrucianism, and Gnosticism. In writing Aleister Crowley, he enjoyed complete access to all Crowley's restricted papers, unpublished letters and personal diaries kept in a trust at London's Warburg Institute and in the Ordo Templi Orientis archives. Ninety percent of the authentic material here has never before been published.
