Erast Fandorin, our erstwhile gentleman sleuth and hero has gone off to serve in the Russo-Turkish War (1877-78) so as to forget his personal sorrows. Captured by the Turks, Fandorin wins his freedom by beating his captor at backgammon. He then encounters a naive, young "progressive" Russian woman trying to join her "husband" at the Russian headquarters. It's here where the action really takes off. Fandorin is requested to investigate certain devious goings-on, and he eventually exposes a well-known French journalist as a Turkish agent (who was one of the children raised by Lady Astair's establishments in The Winter Queen). The new Fandorin thriller is another compelling page-turner from Boris Akunin.
