They were a picture of youth and love - and they were the essence of evil. They were married in a picture-perfect wedding in Niagara-on-the-Lake and they rode off in a horse-drawn carriage. Karla Homolka and Paul Bernardo were the very image of love and success. But they had blood - including the blood of Karla's own younger sister - on their hands. This is the definitive inside account of a serial murder case unparalleled in history. It is a story of a man and a woman joining together in torture and mutilation crimes that are virtually unspeakable. It is a story of sexual depravities videotaped by Bernardo and Homolka themselves - tapes so shocking that a trial judge ordered them destroyed, though they are rumored to have surfaced in New York and Tokyo. It is a story of authorities taking six years and twenty-three victims to stop the killings - even after Paul Bernardo's sister and best friend had both tried to turn him in. Investigative journalist Stephen Williams takes you inside this shocking case - into the motivation of a couple wed in blood, into the details of their crimes and motivations, to perhaps the worst outrage of all; the sweetheart deal that allowed Karla Homolka to escape punishment for her deeds.
