Judith Flynn's cousin Renie has been fascinated by a house in their old neighborhood: while it seems to be occupied, no one is ever seen entering or leaving the place. Now Renie wants to use the facade in a brochure, and needs to find the owners. Despite herself, Judith's curiosity is piqued. She questions a milkman making a delivery, and shortly thereafter finds his dead body in the trunk of her car. She's a suspect, and had better solve the crime while husband Joe is on a business trip, or she'll have to explain how she came to find another corpse.
