The Red Kite Killings — Hylton Smith

Jack Renton was on a rare vacation when he was asked to return and check out a body which had been recovered from the River Tyne. He initially refused. When he was apprised of the victim's mutilation, he became obsessed with an old case, from which he still suffered flashbacks. His team was concerned about such a delusional pursuit, and then a second body was found. Was a copycat killer responsible?
