When Richard Cooper is found shot to death in his luxury apartment in North Sheen, London, Detective Chief Inspector Harry Brock and Detective Sergeant Dave Poole are assigned the case. They immediately question Dennis Jones, who found Cooper’s lifeless body, and Lydia Maxwell, who lived in the apartment opposite – but is either of them telling the truth? Richard Cooper appears to have been a very private man who left few clues behind. As the investigation gathers pace, however, a trip to Belgium could signal the possible unravelling of the mystery. But it soon becomes clear that the hunt for a determined killer could lead to tragedy for Harry and his team.
