The Rusty Sword of Tsar Gorokh

Secret services have always been and will always be!
The bright everyday life of the employees of the 1st Police Department of the town of Lukoshkino is daily diversified by all sorts of black magicians, boyars-troublemakers, the immortal Koshchei (may he not be mentioned at night). On the way of those fairy-tale horrors, an impregnable wall rises in the form of junior lieutenant of the police Nikita Ivanovich Ivashov, private Mit’ka, and the secret adviser Baba Yaga.
In Lukoshkino—the capital town of Tsar Gorokh—former local policeman N.I. Ivashov ended up, by order of unknown forces, from Moscow, and now, for eight novels in a row, he successfully unravels complicated cases, drives away enemies, saves princesses, and outwits clever people.
