A novel by Alistair Croft
The Final Truth
A Sherlock Holmes Novel
The hunt is nearing its end.
For years, the world has believed Sherlock Holmes dead.
Living in the shadows under assumed identities, Holmes has followed a trail of secrets across Europe and America, pursuing one of the most elusive mysteries of his hidden years. At its center lies Saint Peter's Confession—a lost and controversial document whose existence has attracted collectors, criminals, church officials, and some of the most powerful men of the age.
Now the trail leads to New York.
As wealthy rivals gather to compete for possession of the document, Holmes finds himself facing not only the dangerous Sebastian Moran but also the vast influence of Nathaniel Ashcroft, a man whose power seems to reach into every corner of the city. Around them circle art dealers, scholars, forgotten allies, and hidden adversaries, each pursuing their own ambitions as the search for the document reaches its climax.
But the greatest mystery may not be the document itself.
As Holmes follows the final threads of the case, he begins to uncover something far more troubling: a system of power, loyalty, and influence that operates beyond the reach of ordinary laws. To expose the truth, he must confront men who are accustomed to shaping the world according to their will—and discover what happens when such men are finally challenged.
The Final Truth is the thrilling conclusion to The Secret Letters, a four-part Sherlock Holmes adventure set during the detective's mysterious years in exile after the Reichenbach Falls.
Rich in historical atmosphere, international intrigue, hidden identities, and intellectual suspense, this novel brings Holmes face to face with one of the most unusual and dangerous investigations of his career.
