The distant future. Planet Solo-Rex. Detective Nick Boytsov is suspended from duty. But a series of mysterious deaths, the culprits of which the police believe are psionics—people with unusual abilities—forced Boytsov’s superiors to return him to duty. Nick had to establish a connection between the deaths of a number of leading businessmen and politicians and the disappearance of five tons of illegal cargo brought to Solo-Rex from Earth. After all, the ancestral home of humanity has been captured for four hundred years by the Gray Mantle - nanomatter that destroys all living things. The robot servant Punch, who once served the legendary Captain Clov, the first man to land on the lifeless Earth, volunteered to help Nick in his investigation. Nick Boytsov will have to unravel a complex and deadly tangle of intrigue, crime, xenophobia and hatred.
