The Death of Achilles Boris Akunin
When Erast Fandorin returns to his homeland, he becomes immediately involved in an investigation into a political murder aimed at overturning the established order. The motive for the murder is the cruel colonisation of the Caucausus and Chechnya, carried out by the Russians in the mid 20th Century. It is Fandorin's old friend from TURKISH GAMBIT who is unfortunate victim of the assassination.
