Ace of spades. Babitsky S.A.

In the summer of 1875, Moscow shuddered from a series of brutal murders. In the Neskuchny Garden, the villain already stabbed three girls, but not of any blasphemy or philistines, but a maid of honor from the emperor's retinue.

Near each victim they found a playing card - a peak acce. The police lost their feet. I had to turn to the former convict for help, who knows how criminals think.

This is a private detective of Marmeladov, who has served a considerable time for the murder. He is forced to constantly solve puzzles in order not to break again and not allow the darkness to flood his mind.

Who is the killer? A maniac single? Or is a secret society behind crimes? Go, figure out what the damned peak ace hints at.
