Legendary detective duo Leonov—Makovey. In his office, a hunter’s shotgun blast kills the director of a liquor-and-vodka factory, Vladimir Ignatov. MVD colonels Gurov and Kryachko put forward two versions. First: a production conflict—one of the dismissed workers threatened Ignatov with death. And second: revenge by dissatisfied accomplices of the director, who took part with him in stealing factory goods… In addition, the detectives were also interested in Ignatov’s mistress, who had suddenly disappeared and whom he carefully concealed. But the versions fell apart when, outside the city, the victim’s husband was found—shot… with the same sawn-off shotgun used to kill Ignatov. Nikolai Leonov, a former MUR investigator, knew firsthand how the most tangled criminal cases are solved. That’s why each of his books is a truthful, gripping story with an unpredictable intrigue and an unexpected ending. The main hero of these books, Colonel Lev Gurov, is a top-class detective with a wealth of positive human qualities. Friends respect him, enemies fear him, and women love him. He is a real domestic Superman. For forty years, novels about Lev Gurov have consistently attracted fans of Russian detective fiction. The classic series "Black Cat" has over 200 books, released in tens of millions of copies.
