The book of Martin Booth, a famous American publicist, is the first objective, fact-based and archival biography of Aleister Crowley, a notorious writer, magician and public figure. Crowley left behind so many myths and false rumors created by the press and himself that only the calm, sober look of the biographer can recognize the "real" Crowley for "Great Beast 666," a drug addict, bisexual, libertine and egomaniac who considered himself a prophet who stood on a par with God, who believed that he was sent by Secret Teachers to teach humanity the law of true will "Do what you want - that's the whole law."
