Vernon Scripps has really made a killing on the paintings he bought from Steve Crane's mother. He kept one of them though. The one called "Tower Bridge". He organizes an auction for the benefit of Sir Nigel Fethersone's charity foundation and is "persuaded" by Oscar Blaketon to donate the "Tower Bridge" painting himself. But somebody steals the painting and he gets David to make a duplicate. Jenny surprises an intruder at Sergeant Merton's house. He does not hurt her, but only looks firmly at her and walks calmly away. The intruder is Eddie Harvey and he wants the sergeant to tell him the name of the man who grassed on him and an accomplice on a bank robbery. If Merton does not yield Harvey will kill Jenny.
