I. Khmelevskaya appears in this novel as the Polish Dick Francis. The gambling heroine Ioanna is not limited to playing in casinos and slot machine parlors. She has a passion for horses and racing. But, as she herself explains to beginners, winning does not depend on the horse or the jockey. The horse that the mysterious gambling business tycoons have bet on will be the first to reach the finish line. One can only guess who they are, the mafia from Lomzhin near Warsaw, the “new Russians”, high-ranking officials... But one fine day, the fraud at the races suddenly stopped: the horses at the races began to reach the finish line exactly as they should! The best began to come first! The worst come last! For the Warsaw hippodrome, this is not just a miracle - it is extremely suspicious... Naturally, jockeys, grooms, and gamblers begin to speculate and suspect each other, especially since shortly before this, unknown people killed the jockey Derczyk. It so happened that Ioanna came across the body of the last one in the barberry bushes right at the hippodrome and thus found herself drawn into the investigation of a murder and fraud. This time the police welcome the participation of the restless heroine in the investigation...
