Having overflown after the long Irish rains, the river brought to shore the body of a young woman, unrecognizably disfigured by torture. This was the sixth of murders that had broken the peace of a small port town, from which the Titanic had last departed. The criminal’s game was subtle: he skillfully selected beautiful women who resembled each other, and then killed one every month, subjecting them to most terrible torture. The killer left his signature on the bodies of all victims, even wrote meditative letters stating his philosophy of life – but still, he couldn’t be caught.

And thus, the legendary investigator Sean O'Neil, sent from Dublin to Cork to catch the criminal, is facing a challenge: who is the serial killer? A criminal authority that disappeared from the field years ago? A psychopath masquerading as a human being, or a demon of hell from the Purgatory? Will the investigator be able to see the actions of the magician's left hand when all eyes are directed at his right, with which he takes a rabbit out of a hat?
