The commissar Maigret meets Mr. Motte, a lawer from Chateauneuf. He tells Maigret that somebody has stolen his collection of oriental miniatures. He suspects Gerard Donovant, the fiancées of one of his daughters, Armande. However, the whole business is strange, as no one could sell these objects since they are easily identifiable.
Maigret goes to Chateauneuf disguised as Mr. Legros, an old army friend of Mr. Motte. Here, he recognizes the one who pretended to be Donovant as Gerard Gassin, the son of a an international swindler, the Commodore. Gerard, who recognizes Maigret, is convinced that the inspector has only come to stop his marriage with Armande.
