Billy and Timmy earn a little extra pocket money by collecting golf balls. One day Billy finds his friend assaulted in the woods by the golf course. Jimmy says he was attacked by a man sitting in a grey Jaguar with another man and a lot of papers. He even identifies the man from a photograph that PC Rowan has borrowed from the club secretary Harry Fell. Severe stomach pains prevent Greengrass from placing a bet for a "friend", and the old scoundrel wishes he could disappear. Changes are on the way within the police and Inspector Barry commandeers sergeant Blaketon's office while he makes his report. Blaketon fears for his position and starts looking for another job.
