The Viscount de Moreau, an aristocrat who investigates not by profession, but by vocation, finds himself embroiled in a new, extremely complicated case. Before him are four women, each of whom is beautiful, but one of them may be responsible for the death of an army captain. Now the Viscount will have to understand the intrigues and at the same time not get caught in the silk net... De Moro is sure of one thing: love is the basis of the crime. Literary adaptation by O. Koltsova.
