The illusion seems part political hocus-pocus and also part wishful thinking, for among many Russians Stalin is again popular; the bloody dictator can boast a two-to-one approval rating. Decidedly better than that of Renko, whose lover, Eva, has left him for Detective Nikolai Isakov, a charismatic veteran of the civil war in Chechnya, a hero of the far right and, Renko suspects, a killer for hire. The cases entwine, and Renkos quests become a personal inquiry fueled by jealousy. The investigation leads to the fields of Tver outside of Moscow, where once a million soldiers fought. There, amidst the detritus, Renko must confront the ghost of his own father, a favorite general of Stalins. In these barren fields, patriots and shady entrepreneurs -- the Red Diggers and Black Diggers -- collect the bones, weapons and personal effects of slain World War II soldiers, and find that even among the dead there are surprises.
