Antique dealer Vseslavin died in the hospital from a pulmonary infection. But for some reason his wife Tamara is sure that her husband was deliberately killed. She turned to the famous private detective Tatyana Ivanova to find the culprit. Tatyana initially decided that the case would be very easy - what could be criminal in such a diagnosis? However, as she got acquainted with the details of the life of the antique dealer, she realized: everything is not so simple - the recent robbery of a local museum, to which, according to his wife, Vseslavin was related, the replacement of original paintings with copies, fierce competition among connoisseurs of artistic values - all this suggested that someone could really have a grudge against Tamara’s husband. In addition, the choice of method of murder indicated that this time Tatyana’s opponent was a very inventive person!
