This is the the sad story of a car manufacturer, short of the readies, who asks his wife for money (for she owns the fortune). She refuses for her dad bankrupted himself and she would not be able to stand poverty again. He contemplates suicide but someone comes to his rescue and there's still hope: they can win the "Circuit De Minuit", a motor race. Besides, there's a another woman who cares for him.

Mado, la peu farouche concierge d'un immeuble montmartrois, est poignardée. L'inspecteur Brénot enquête. Il est secondé par une fort jolie femme, Irène Cazeneuve, nouvellement installée, veuve de l'un de ses collègues. Elle se révèle une excellente adjointe, interrogeant avec plus ou moins de discrétion selon les besoins divers suspects : un masseur équivoque, un prédicateur et son fils, un jeune professeur de latin... Mais l'assassin figure-t-il vraiment parmi cette liste ?
