How well do you really know your friends? Meet Louise, the PA from Plymouth who faked surrogate pregnancies for money. Then there's Emile, the popular army sergeant who sabotaged his wife's parachute. And here's Gayle, the creative-writing graduate who, while pretending to be a man, tricked a female friend into having sex with her. These normal-seeming people were quietly wrecking lives, and nobody suspected them. The addictive weekly podcast 'They Walk Among Us' serves up small-town horror stories in gripping detail, hooking millions of listeners. Now, in their first book, Benjamin and Rosie exclusively dig into eight of the most intricate and disturbing cases in their dossier of deviants - Emile, Louise and Gayle included - to provide an unforgettably sinister true-crime experience.
