There has been three break-ins within a week already and the fourth item on the burglars' "shopping list" is the Aidensfield Arms. Nothing but money was taken, and the police are without a clue until Aunt Peggy and other old people receive an anonymous envelope with 20 pounds each. Money that comes from the break-ins. Furthermore Carol Cassidy saw a car in Aidensfield at the time of the break-in at the pub with a man and a woman in it. PC Mason readily admits that he was the man, but to Carol's great annoyance he does not say anything about who the woman was. Douglas Philpot asks Oscar Blaketon and Alf Ventress to look for his son Ian, whom he and his wife Mary have not heard from for three months. A colleague of his also saw him at a night club in Whitby, but that is all. The two sleuths have a feeling though that Mary Philpot knows more than she is willing to say with her husband present.
