Book excerpt: A man alone in a bedsit with a young woman friend, who suddenly unleashes a deadly onslaught, without warning or reason. The stabs don't hurt. They seem more like punches. Then he realises that the red liquid pumping out of his body and on to the floor is his blood. He doesn't realise, as he drifts into unconsciousness before death supervenes, that he'll never wake up again... In March 2013, Joanne Dennehy stabbed three Peterborough men to death within the space of a few days. One was her landlord, Kevin Lee. Dennehy and her sidekick, Gary Stretch, put the body into a wheelie bin and dumped his corpse in a ditch close to White Post Road in the Parish of Newborough. Lukasz Slaboszewski and John Chapman were stabbed to death and disposed of in a farmland ditch several miles away. She then attempted to murder two other men. By the grace of God they survived. Jo Dennehy is unique, for she now ranks alongside Myra Hindley and Rosemary West as one of the most heinous female serial killers in British criminal history. Only her death will bring about her release from prison. This book, by a leading criminologist and expert on serial killers, has been written with the full cooperation of the police involved in the case, and many of those who knew Joanne Dennehy and her victims.
