About the book: 2020 / During the usual inspection of the condition of the Summer Garden, senior policeman Fedulin was faced with a terrible discovery. In the middle of the pond, a little girl swam on her back, legs and arms outstretched and her curly head thrown back. The victim turned out to be the only daughter of court councilor Kartaikin, who was kidnapped right on the street a few days ago. An examination showed that before throwing the girl into the pond, the killer strangled her. But who needed to kill the little noblewoman? The chief of the gendarmerie, Benckendorff, and the chief of police, Kokoshkin, will have to investigate this complex and complicated case. And while senior police officials are looking for evidence, St. Petersburg does not stop talking - news about the murders of young girls spreads at the speed of light. Who is he - a dangerous and crazed maniac? Perhaps Joseph Charlemagne, whose brother created one of the fences of the Summer Garden, will be able to solve this mystery.
