A new novel from the series “Secrets of the Forgotten Island” about the adventures of detective Serebryak Sharp-Sniffing. The famous weasel detective begins a new investigation. Probably, only the brilliant Sherlock Holmes could compete with him when it comes to solving some puzzling riddle or getting on the trail of treacherous villains. This time, Sharp-Sniff is faced with two tasks. He certainly needs to disrupt the plans of the insidious Screwtape, who intends to blow up the capital of the Celestial Island, and in addition, find the prince of lemmings, who, having left the ship's ladder, disappeared in the most mysterious way.
