Seduced by the beauty of the Cote d'Azur and the low prices of the spring season, prosecutor's office investigator Maria Shvetsova, together with her husband and friends, went on vacation to Nice. But crime exists everywhere, even under the skies of beautiful France. And on vacation, the world of crime does not leave Masha alone: breaking into the villa where the company settled, open surveillance of their movements and an attack on Shvetsova herself. Perhaps the object of interest of the unknown is her friend, the beauty Regina, or do the criminals have other motives?..Masha leaves France in complete bewilderment. However, the solution to the criminal story, as always, awaits her on the banks of the Neva. And as always, it all starts with a murder... All this and more is in the book.
