January 1905: Holmes and Watson are summoned to undertake a clandestine investigation. An agent of the British Secret Service has been found floating in the Thames, carrying a manuscript smuggled into England at the cost of her life. The pages purport to be the minutes of a meeting of a secret group intent on taking over the world. In this Holmes tribute by the author of the 1974 classic The Seven Per-Cent Solution, the famed duo—in the company of a bewitching woman—take the Orient Express from Paris into the heart of Tsarist Russia, where they uncover a conspiracy so vast that even Holmes may not be able to stop it.
