The first of the interlinked plotlines is set in Russia during the Russo-Japanese War in 1905. Fandorin is charged with protecting the Trans-Siberian Railway from Japanese sabotage in a pacy adventure filled with double agents and ticking bombs. Then we travel back to the Japan of the late 1870s. This is the story of Fandorin`s arrival and life in Yokohama, his first meeting with Masa and the martial arts education that came in so handy later. He investigates the death of a Russian ship-captain, fights for a woman, exposes double-agents in the Japanese police, fights against, and then with the ninjas, and becomes embroiled in a shocking finale that interweaves the two stories and ties up the series as a whole.
