Arkady Renko returns in this tense political thriller, from one of the undisputed masters of the genre.   When Arkady Renko is charged with investigating the murder of Alexei Kazasky, the Deputy Minister of Defence, he knows he has to tread carefully. Alexei Kazasky is a high-profile politician and has a complicated relationship with Putin. This investigation clearly has Kremlin approval, but, as with everything in Russia, things are not always what they seem.   Already preoccupied with his developing Parkinson’s, Arkady finds he has more to worry about. The war in Ukraine is gaining momentum, and his son Zhenya has become involved with the Black Army, a Russo-Ukrainian group of hacktivists. Moreover, as Arkady digs deeper into Kazasky’s murder, he realizes that the man’s death may have been more politically motivated than he first assumed.   Now it seems that the people behind the killing have him firmly in their crosshairs – but this time Arkady’s life is not the only one on the line.PRAISE FOR MARTIN CRUZ SMITH:   'The later Renko novels are stark, spare and beautiful, like trees in winter.
