When a young woman with a dark past is found dead on the streets of Paris, Inspector Maigret is on the case. This is the forty-third book in the new Penguin Maigret series.

A young woman named Lulu, who has a history of brushes with the law and once lived on the streets of the 18th arrondissement, is found murdered in Paris. Maigret is called to the scene and soon learns that her boyfriend, a musician, has gone into hiding upon reading the news of her death. And when the Inspector learns that the young victim was pregnant, he begins to suspect the case might be more sinister than he imagined.

Librarian's note: this entry is for the novel "Maigret se trompe." #43 in the series. In English "Maigret's Mistake." Amazingly there is also a Maigret short story by Simenon with the same English title; it's original in French is "Une erreur de Maigret." The stories are not related in content.
