Stalin's Ghost - Martin Cruz Smith (Arkady Renko #6)

Winter is what Muscovites live for. Knee-deep snow softens the city and flows from golden dome to golden dome. Snow drives the common citizen into the Metro, where stations are still "Palace of the Proletariat." There on the platform people see the ghosts of Joseph Stalin. Not everyone, it seems, likes the fact that Stalin is dead...

Assigned to this delicate matter is the pariah of the Prosecutor's Office, Senior Investigator Arkady Renko.

But in the midst of a blizzard, nothing is as it first appears to be. Renko's girlfriend and his adopted son seem to be slipping into danger. A chess grandmaster wanders into Renko's life and leads him into the line of fire. Diehard Communists gather to ding along with Stalin. "Red Diggers" uncover secrets buried for half a century in a desolate forest and Renko discovers ghosts that have been waiting for him all his life...
