Losing Streak - S11.E51

Beech and Monroe are at loggerheads following the recovery of the body of a drowned bookmaker from the Thames. Beech suspects that one of his clients, Brian Mackay, has something to hide when he breaks into the dead man's office to steal his client file. However, Monroe is more concerned by the suspicious activity of the man's son-in-law and attempts to bring Beech around to his idea of a motive.
