One Dead Commissar At an icebound naval weather station in far Siberia, the young daughter of an exiled dies under suspicious circumstances. The high-ranking Commissar sent to investigate the mystery suffers a similar fate: he is murdered by an icicle thrust into his skull. One Live Cop Inspector Porfiry Rostnikov is dispatched to solve the Commissar's murder, with one caveat: he is not to investigate the girl's death. Even if all the clues tell him that the two cases are linked. One Cold Killer In a single, fateful day, Rostnikov will hear two confessions, watch someone die, conspire against the government, and nearly meet his own death. All under the watchful eye of the KGB -- and someone much closer and infinitely more terrifying.
