Imagine that you are a doctor who saves dozens of patients from death every day, including after an assassination attempt. You don't care who shot the poor guy, you're just trying your best to keep him alive. What will you do if one day you fail to save the patient, and your own wife turns out to be under suspicion of his murder? In the frivolous Paris of the "roaring twenties", where White Guard colonels turn the steering wheel of a taxi, emancipated women shorten skirts and lengthen lists of lovers, and antique dealers sell dubious masterpieces, a famous art dealer is shot. He dies right on the operating table of the Russian doctor Alexander Voronin. But the most surprising thing is that the death of the antiquarian is blamed... the doctor's wife. Voronin intends to save his wife from the guillotine at any cost, but for some reason she does not appreciate his efforts at all. The search for the real killer threatens to destroy their marriage... Shortlist of the Russian Detective Award in the "Discovery of the Year" nomination.
