The smartest of all the smartest detective Gerard is back on the case! Guinea pig investigations continue even during the summer holidays in the country, at the Vytivka farm. This time, such adventures await Gerard, for which even he was not ready. A sleepy summer vacation was interrupted by a terrible harmider in the chicken kingdom of the cock of Suleiman the Magnificent - and only Gerard could grab the troublemaker by the tail. But after solving the first case, the second and the third inevitably happen: a big horned monster stalks Gerard and company, races and hunts, as well as the secrets of Vytivka's nightlife.
