Legendary detective duo Leonov—Makovey. Millionaire Petr Vershinin seems to have luck in everything: a profitable business, a young beautiful wife, reliable friends, and a rare art gallery in his own mansion under Sochi. Suddenly, the millionaire hits a black streak. A fire breaks out on the estate—part of the collection is destroyed. An unknown shooter fires at the mansion’s window, attempting on the businessman's wife. Vershinin offers the MVD colonel, Gurov, to live with him and help identify the villain. Gurov suspects everyone living in the house: artists, the businessman—Vershinin’s friend, security guards, the millionaire’s wife, his son and daughter… However, the detective has no direct evidence. Everything changes when, on a walk one day, Gurov nearly dies in a staged trap… Nikolai Leonov, a former MUR investigator, knew firsthand how the most tangled criminal cases are solved.

He is a real domestic Superman. Novels about Lev Gurov have been drawing fans of Russian detective fiction for forty years without fail.
