Six kilometers from the city of Magaran, not far from the roadside, in the bushes, investigators found a half-rotted sack with parts of the human body. Forty meters from the sack containing the torso—whose head and limbs had been severed—there was a bundle of burlap in which were the legs and the left arm of a man with a tattoo: DSK. The victim’s head was not found. Who could commit such a monstrous crime of cruelty? Who was the dead man? Why did he suffer such an awful execution? The investigation has accumulated too many questions, and, judging by everything, the local police authorities will have insufficient forces and experience to carry out the investigation. The help of the best criminal investigation officers comes—headed by the investigator for especially important cases, Colonel Kostenko.
