“No trouble, but trouble helped!”—the proverb proved itself right to Ivan Pavlovich Podushkin, the long-time secretary of the detective agency “Niro.” Vanya became the owner of a new car, which he received as a fee from the chief editor of the newspaper “Chas Pik.” The editor asks Podushkin to find the employee who leaks exclusive information to competitors. Ivan Pavlovich was lucky: on his very first day, he learned the traitor’s name. It was Natasha Kapustina. But—what a letdown! She had an iron alibi. Besides, Kapustina admitted that she is his colleague—a private detective. Vanya didn’t manage to find out anything else—the girl was hit by a car. Was it an accident or a murder? That’s what Podushkin has to figure out, and at the same time prove to Eleonora—who went to England for a meeting of the club “The Children of Sherlock Holmes”—that he can handle it all even on his own.
