Stalin's Ghost by Martin Cruz Smith

Moscow-based Senior Investigator Arkady Renko, in his outstanding sixth outing (after Wolves Eat Dogs), investigates a murder-for-hire scheme that leads him to suspect two fellow police detectives, Nikolai Isakov and Marat Urman, both former members of Russia's elite Black Berets, who served in Chechnya. Isakov, a war hero, is now running for public office. Renko must also look into reports that the ghost of Stalin has begun appearing on subway platforms and why several bodies of Black Berets who served in Chechnya with Isakov have turned up in the morgue. Despite repeated threats to his life, Renko stubbornly perseveres, seeking justice in a land that has no official notion of that concept. Smith eschews vertiginous twists and surprises, concentrating instead on Renko as he slowly and patiently builds his case until the pieces fall together and he has again, if not exactly triumphed, at least survived. This masterful suspense novel casts a searing light on contemporary Russia.
