Suspects
Overview
Jack and Charlie investigate an assault on the owner of the Green Pit nightclub in east London and discover the victim's sister unconscious in the cellar, with blood pouring from a head wound. The detectives' efforts to piece together what happened are hampered by the lack of CCTV footage, and the case takes a confusing turn when a 19-year-old student is found dead with a flyer for the club in his pocket.
