Meadows and Price realise that the only way of clearing their names is to track down witness Henry Thorpe before Manson and Keane do. Meadows' son Benjamin is then found beaten in his prison cell, and Nixon and Webb discover that Parker was behind the recent spate of robberies comitted on Benjamin's behalf. Meanwhile, Meadows visits villain Jimmy Hastings in an attempt to find out who the real robber on the armed blag was. Hastings claimed that 'Fat' Freddie Thornton was the second man, but with Thornton having been missing for over twenty years, Price seems to think Hastings is leading them up the garden path - until Meadows manages to track Thornton down.
