A burglary at Harrowfield mortuary. The body of 30 year old Kirsty Gallagher is missing. Nearby, uniform police are searching the canal along with a small diving squad, following the discovery of some clothes by the bank side. The body of a naked man is hoisted from the murky depths. His ankles are tied by a piece of rope connected to concrete. Kirsty's decomposing corpse is eventually found and an arrest is made which leads to a network of men whom D.I Dylan can only describe as reprobates.
