The reactionary Adjutant General Khrapov, newly appointed governor-general of Siberia and soon-to-be minister of the interior, is murdered in his official saloon carriage on his way from St. Petersburg to Moscow. The killer, disguised as Fandorin, boards the train at Klin, where it has been delayed by snowdrifts on the line. This translation origin.
In this one, Fandorin has signed on as a Counsellor with a prince who also runs the various police departments in Moscow, just as the anarchist movement is blowing things up. The dual track of the anarchist leader and Fandorin is well managed, and the subtle politics is definitely worth the read.
note: Fandorin has spent time in the East, and has a Japanese manservant and physical trainer who could have been the straightfaced basis for Inspector Clouseau's manservant in the Peter Sellers movies. Fandorin's guests are inevitably surprised by the man and the physical training they witness.
