From the author of million-copy bestseller, Flowers for Algernon , the shocking true story of a troubled young man and his splintered, terrifying world. Inspiration for the new TV series THE CROWDED ROOM starring Tom Holland ' An absorbing, often heart-rending exploration of the human mind' Cosmopolitan 'Fascinating' LA Times '[Keyes] has carried it off brilliantly, bringing not only a fine clarity but a special warmth and empathy' Washington Post Billy Milligan was a man tormented by twenty-four distinct personalities battling for supremacy - a battle that culminated when he awoke in jail, arrested for the kidnap and rape of three women. In a landmark trial, Billy was acquitted of his crimes by reason of insanity caused by multiple personality disorder - the first such court decision in history. Among the twenty-four are: Philip, a petty criminal; Kevin, who dealt drugs; April, whose only ambition was to kill Billy's stepfather; Adalana, the shy, affection-starved lesbian who 'used' Billy's body in the rapes that led to his arrest; David, the eight-year-old 'keeper of the pain'; and the Teacher, the sum of all Billy's alter egos fused into one. In The Minds of Billy Milligan , Daniel Keyes brings to light the most remarkable and harrowing case of multiple personality ever recorded.
