Captain Alexei Dimitrevich Korolev

Moscow, 1936. In a deconsecrated church, a young woman is found dead, her mutilated body displayed on the altar for all to see. Captain Alexei Dimitrevich Korolev is asked to investigate. But when he discovers that the victim is an American citizen, the NKVD - the most feared organisation in Russia - becomes involved. Soon, Korolev’s every step is under close scrutiny and one false move will mean exile to the frozen camps of the far north. Committed to uncovering the truth, Korolov enters the realm of the Thieves, who run Moscow’s underworld.

Following a previous investigation, which implicated those at the very top in Soviet Russia, Captain Alexei Korolev finds himself hailed as an example to all. But Korolev lives in an uneasy peace - if it is discovered what his real actions were during the case, he will face deportation to Siberia. Instead, Colonel Rodinov of the NKVD security service asks the detective to look into the suspected suicide of a young woman on a film set in the Ukraine. The feared commissar for State Security, Ezhov, wants the matter looked into.

Moscow, 1937. Captain Korolev, a police investigator, is enjoying a long-overdue visit from his young son, Yuri, when an eminent scientist is shot dead within sight of the Kremlin, and Korolev is ordered to find the killer. It soon emerges that the victim, a man who it appears would stop at nothing to fulfil his ambitions, was engaged in research of great interest to those at the very top ranks of Soviet power.
