A New York Times Bestselling Author
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 nothing less than taking over the world. The adventure takes the famed duo aboard the Orient Express from Paris into the heart of Tsarist Russia. What they uncover is a conspiracy so vast as to challenge Sherlock Holmes as never before.
