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.

It is 1937, and Captain Alexei Korolev finds himself on an airplane bound for Odessa after the suspicious suicide of a loyal young party member who supposedly had an illicit relationship with the party director. His instructions are to determine if her suicide was actually a cover-up for murder, and if so, to find her killer. She was working on the set of a movie subsidized by the state, and the pool of possible suspects is large and daunting. Korolev finds help from several quarters, but none of them can make up for the one important fact of his case which he cannot discuss.

Captain Alexei Korolev has nothing to complain about. He has his own room in an apartment, a job in the police force that puts food on the table, and his good health. In Moscow in 1937, that's a lot more than most people have to be grateful for. Korolev receives an urgent call from his boss - it seems an important man has been murdered, and Korolev is the only detective they're willing to assign to this sensitive case.

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.
