Description:A body has been found, dumped in the Bois de Boulogne, face battered. Aristide Fumel, M's old colleague from the 16th, calls him about it, though under present rules the Public Prosecutor's<br>
office is bound to feel it's outside of M's province, and besides, he's<br>
supposed to be working on the rash of robberies. But M goes to the park<br>
and recognizes the body, Honoré Cuendet, a quiet burglar M had known for 30 years. M goes to Justine Cuendet's,<br>
Honoré's mother's, to let her know. The only clue, a couple of<br>
wildcat's hairs, as from a car rug, had been found on his jacket. This<br>
unofficial investigation of M's is interrupted when a robbery takes<br>
place on the Rue La Fayette,<br>
and an off-duty constable on the scene had shot one of the robbers. It<br>
seems like finally a break into the gang, which M believes to be headed<br>
by Fernand, recently released from prison, whereabouts unknown. <br>Meanwhile Fumel has picked up Cuendet's trail — he'd been living in a little hotel on the Rue Neuve-Saint-Pierre, opposite the mansion of Mrs. Florence Wilton.<br>
Apparently that was his next target. M sends a man to keep watch from<br>
Cuendet's hotel room. On the robbery case, some connections have been<br>
made to the wounded man's associates, especially his friend René Lussac, who spends time in the Café des Amis near the Porte de Versailles. M inquires about the Wilton's, but is told that investigating them wouldn't be a good idea, as Stuart Wilton is "a good friend of France". A trace of a call made by Lussac leads to a villa outside Corbeil,<br>
where it appears Fernand is probably holed up. A simultaneous raid is<br>
planned for the villa and the Café des Amis, and it is successful, while<br>
in Montmartre, Lognon has recognized Cuendet's picture, leading M to<br>
his girlfriend, Éveline Schneider.<br>
Engough evidence — the stolen money — is accumulated in the robbery to<br>
make a case for the arrests. M is convinced that Cuendet had been caught<br>
in the act by Stuart Wilton's son, his ex-wife's mistress, and killed<br>
so that he wouldn't be able to reveal the relationship. The lack<br>
evidence and social position of the probably culprits make it worthless<br>
to follow up. M tells Éveline that there should be some money for her<br>
and Cuendet's mother somewhere among his things... <br>
