John was waiting for me.

He tied my ankles and my wrists to ropes concealed on the bed, and threatened me with a gun and knife. Then he revealed that he had killed his former girlfriend!

When Delia Balmer entered into a relationship with John Sweeney, she had no idea he was a serial killer. At first he was attentive and caring, but over the course of their relationship he became violent and controlling. On more than one occasion he held Delia hostage and tortured her.

During a final frenzied attack, he left her on the brink of death, before going on the run. Astonishingly, it would take the police six years to capture and convict Sweeney of multiple murders.

This is Delia's compelling memoir.

Previously published as Living with a Serial Killer, this is the true story behind the ITV drama, Until I Kill You
