Jakub Krause suffers from an unusual affliction – every Saturday night, at midnight on the dot, he loses consciousness and wakes up as one of the cruellest serial killers in history. He spends the whole of Sunday hunting his victims, and when he comes to on Monday morning, he cannot remember anything of the previous twenty-four hours. In Bolesławiec, the mutilated body of Kaja Rzeplińska is found together with a letter containing the words of Ted Bundy, and Detective Inspector Błażej Heller takes over the case. He is assigned a junior sergeant, Malwina Zygart, the daughter of the notorious serial killer known as Raptor. Ten years earlier Raptor took Heller's wife from him, which is why he does not trust his new partner. Yet as further brutal murders follow, the two of them must join forces to stop a monster that is growing ever stronger. "I HAVE TO KEEP TELLING MYSELF THAT THIS IS NOT MY FAULT, AND PUSH THE EVIL AWAY. OTHERWISE THERE WILL BE A TOTAL CATASTROPHE."
