Tommy Lee Royce, the father of her grandchild and the man who nearly killed her, may be in prison, but he’s still very much in Catherine’s thoughts.
While on duty Catherine makes a gruesome discovery – a body. The victim’s injuries bear a striking similarity to a string of other murders over the previous few months, suggesting a serial killer is on the loose. But the case becomes even more shocking when it emerges that Catherine knows the victim – something that could have significant repercussions for both herself and her family.
Elsewhere, Detective John Wadsworth is struggling to put an end to an affair that is rapidly spiralling out of control and Tommy forms a bond with a mysterious female admirer despite being behind bars.
