Chillingly, he also confessed to the murder of his previous girlfriend. After one serious assault, Sweeney was released on bail, and left her in the utmost fear knowing that he would return to finish her off. After a final frenzied attack leaving Delia on the brink of death, Sweeney went on the run. Astonishingly, it would take the police six years to capture and convict Sweeney of multiple murders.

This is her compelling memoir. Previously published as Living With a Serial Killer, this is the true story behind the ITV drama, Until I Kill You.
