On a violent stormy night, a cargo-and-passenger ferry “Renata” sank for no known reason while making regular trips from Tallinn to Stockholm. And 12,000 kilometers to the east, in Primorye, a helicopter carrying a cargo of gold crashed in the taiga—gold that disappeared without a trace. In Sochi, the head of the criminal investigation department was killed under unknown circumstances. No connection between these tragic events was apparent when the case was assigned to A.B. Turetsky, an investigator for particularly important cases of the Russian Prosecutor General’s Office.
