Major Yarovoy is a man of war. At the head of a small group, he makes a reconnaissance raid in mountainous Chechnya. The task is to track the movement of the bandit group, unravel the plans of the militants, and transmit all information via radio to military analysts. And if possible... survive. Major Yarovoy's group completes the task and returns to their own. It seemed that all the dangers were behind us, but new challenges awaited the major, perhaps tougher than in hostile mountain gorges... The story is about male friendship, about one of the secret operations of Russian counterintelligence in Chechnya, and, of course, about love. A significant part of the novel is occupied by the storyline about the duel between two brilliant war strategists. The author's title of the novel is “Tango of Bloody Nights.”
