Last serialized episode. A soldier is murdered while doing his rounds at night. Jardine and Sergeant Tom Renshaw set out to solve the case. Renshaw is a rather unpleasant character who abuses his men rather than question them. Meanwhile, new DI Robbie Ross and Fraser are investigating counterfeiters at a race meeting, after a horse disappears. First appearance of DI Robbie Ross (John Michie) (thetvdb.com)
