PC Bellamy is in trouble. There was a break-in on his beat while he was visiting one of his girlfriends. Witnesses noticed a noisy minivan speeding away from the scene of the crime immediately afterwards. An anonymous tip leads to part of the loot - and Phil Bellamy's address. Blaketon has no choice but to suspend him from duty. Greengrass notices a fast, black greyhound and spots an opportunity to make a bob or two because it's a dead ringer for ruthless businessman Jack Scarman's somewhat slower dog Northern Flash. If only they can "borrow" it from its owner Mr. Parrish and swap the two.
