Somehow, Olga Boykova, editor-in-chief of the newspaper “Witness,” did not immediately have a vacation on the Black Sea. Before she had time to really get used to the hotel, the murder of its owner, businessman Sochnikov, took place there. To the police who arrived at the crime scene, everything is very clear: the man was killed by his wife Sabina. And all the evidence, it would seem, is really against her - Sabina was seen near the corpse with a bloody dagger in her hand. And the motive is obvious: why shouldn’t the young beauty get rid of her stingy elderly husband and become the owner of a hotel herself, bringing in a good income? But Olga Boykova, having seen enough of the progress of the investigation, does not agree with the official version and is sure that the killer is not Sabina. There will be a number if she can prove it and outdo the police!
