Serafima Nechaeva, an employee of the art gallery, was proud of her work, although her friend Zoyka believed that she could only be ashamed and hidden. But it turned out that violent passions can also boil in their provincial museum: after the exhibition, Sima was missing one of the paintings - a portrait of a lady in black. It is completely unclear who needed it: the author of “The Lady” is little known, but for some reason the thief coveted it, passing by the originals of Repin and Aivazovsky. The police believed that local drug addicts decided to get money for a dose. But Sima immediately suspected that “The Lady” was stolen for a reason. Does the painting have a “double bottom”?
