Leonard Swindley gets himself involved with a married woman and her jealous husband at Dobson and Hawks' January sales. It all starts when Swindley sells Wally Hunt's wife's £75 fur coat (which he was taking to the furriers for shortening) for £4 19s 6d in the bargain basement. Swindley attempts to get it back. He finally traces the coat to one of the store's assistants, Miss Huxley, but unfortunately for Swindley she has a very large jealous husband who misunderstands what Swindley is after. After the encounter Swindley finds he has no permanent injury, just a lot of bruises. At the least the coat has been returned but Swindley's troubles are not over as Hunt discovers that his raincoat, left to dry on a storeroom radiator, has also been sold in the sale...
