Rules of the Game (1)

Overview

A suitcase is found abandoned at Heathrow Airport, and panic ensues, but it is soon discovered to be no terrorist threat. Inside is the naked body of Sofia Petrenko, a high-class prostitute, who has been strangled to death. The suitcase is traced to Vitali Malikov, a Ukrainian billionaire who admits to hiring Sofia's services, but he claims she was alive when she left him and that the case was a gift. D.C.S. Walker arrests Malikov on suspicion of murder, but later has to release him, and soon realises he has become a pawn in a much bigger game.
