Roy Brooks receive a 6-month sentence for horse theft, but the sentence is suspended because he has to keep his family together after his wife's recent death. But it is an uphill struggle because he has a serious drinking problem. The following night the race horse Rio Boy is stolen from Lord Ashfordly's stables and Brooks gets under suspicion because his lorry matches the description of the one used by the thieves. Bernie Scripps accidentally tells Greengrass that he has psychic powers. When the old scoundrel has stopped laughing he gets the idea that they might as well cash in on it. Understandably Scripps does not agree. Phil Bellamy is babysitting Maggie Bolton's son Sam, but when he wakes up from a little nap to feed the baby Sam has gone missing.

Mr. and Mrs. Elder had a break-in and nearly 3,000 £ were stolen together with some petty stuff. The petty stuff is promptly found. It was thrown from a moving car and landed on Dr. Merrick's lawn. Later Dr. Merrick also identifies the car as the one belonging to the Elders. This puts Mr. Elder in the hot seat as the prime suspect, because he does not have an alibi. The solicitor Helen Aves is looking for Winston and Reginald Parker, the relatives of a client. Sergeant Merton assigns the case to Alf Ventress, who is now working as a civilian at the police station, but Oscar Blaketon has already offered his services as a private investigator as well. They join forces and hire David as a driver. But that is just about the only thing the two sleuths agree on.
