Theft and isolated cases of kleptomania don't seem to be a serious enough matter to be dealt with by a famous detective. At first glance, the stolen items seem to be unrelated and have no value, except for a diamond ring. But even that is quickly found when Hercule Poirot appears on the doorstep of the boarding house. It is enough for the detective to threaten the police, and one of the residents immediately admits that she has stolen some things. But not all of them. The next morning, the thief is found dead, and the things are still missing. A simple case turns into a series of mysterious murders, and only Detective Poirot can logically connect all the thefts and identify the real thief and killer, as well as reveal his (or her) motives.
