When Sherlock visits his brother, what he finds shocks him to the core: a locked room, a dead body and Mycroft holding a knife. The police are convinced Mycroft is a murderer, but Sherlock is just as convinced he is innocent. Threatened with the gallows, Mycroft needs Sherlock to save him. The search for the truth necessitates an incredible journey where Sherlock is afoot in a world of secrets and danger.

Even as a teenager, Sherlock Holmes is ready to solve any mystery and inevitably pursue danger. When he comes up against John Wilkes Booth, President Abraham Lincoln’s assassin, and his coconspirators, Sherlock just might not yet be man enough to stop a second Civil War from starting.
