A pernicious assassination plot. A devious decoy. And a transcontinental race against time to catch a killer...

Narrated by award-winning Simon Prebble and Wendy Tremont King.

London, 1898. Held captive by a diabolical criminal mastermind and his gang of thugs, Watson overhears an assassination plot that not only endangers the life of Sherlock Holmes, but threatens to ignite a war. If he has any hope of foiling his kidnappers’ nefarious plans, he must escape - and quickly.

Eluding the familiar foe proves challenging, however. Watson is soon caught and awakens in jail, the prime suspect for two murders, dressed in the clothes of a missing man, one Lord Harwell. To save himself and prevent the assassination, Watson embarks on a dangerous game of cat-and-mouse that leads him on a harrowing journey to Constantinople aboard the famed Orient Express.

Meanwhile, Sherlock and Lucy have been called upon to discern the whereabouts of the missing Lord Harwell. The stakes become much higher when Holmes discovers the missing man has ties to an important diplomatic negotiation in Constantinople.

Just as he is pulled deeper into the investigation, Holmes receives a distressing telegram from Watson himself. He and Lucy quickly board the next outgoing Orient Express in hopes of rescuing Watson and preventing a gruesome act that could very well lead the nation to war.

Success seems uncertain as the enemy looks to thwart their heroic efforts at every turn, and Watson, Holmes, and Lucy become targets in an even more sinister plan. Will three intrepid detectives stop the assassination and put its mastermind away for good? Or, will it all be too little, too late?

A thrilling and fast-paced take on a classic Sherlock whodunit, complete with unexpected twists and turns, international intrigue, and historical events and settings. Faithful to the spirit of the beloved original series with a new dynamic and new characters that will please diehard fans and new fans alike.
