When identical twins June and Jennifer Gibbons were three they began to reject communication with anyone but each other, and so began a childhood bound together in a strange and secret world. As they grew up, love, hate, and genius united to push them to the extreme margins of society and, following a five-week spree of vandalism and arson, the silent twins were sentenced to a grueling twelve-year detention in Broadmoor.Award-winning investigative journalist Marjorie Wallace delves into the twins' silent world, revealing their genius, alienation, and the mystic bond by which the extremes of good and evil ended in possession and death.
