This is an utterly compelling and often unbelievable adventure into the world of madness. Jon Ronson meets everybody from a Broadmoor inmate who swears he faked a mental disorder to get a lighter sentence but is now stuck there to the influential psychologist who developed the industry standard Psychopath Test and who is convinced that many important CEOs and politicians are in fact psychopaths. Combining Jon's trademark humour, charm and investigative incision, The Psychopath Test is a deeply honest book unearthing dangerous truths and asking serious questions about how we define normality in a world where we are increasingly judged by our maddest edges. 'Ronson's new book is provocative and interesting, and you will, I guarantee, zip merrily through it' Observer 'Both screamingly funny and deeply disturbing' Tatler 'Ronson is such a chirpy, inquisitive and funny writer' Mail on Sunday
