In The Six Messiahs, Mark Frost creates a vel of nineteenth-century mystery, adventure, and terror with Arthur Conan Doyle - the creator of the Sherlock Holmes books - at the center of the heart-stopping action. Now off to America for his first book tour, Doyle is joined by his impetuous younger brother, Innes, and a cryptic Irish priest. During their voyage across the Atlantic, the men are stalked by an otherworldly order of assassins attempting to steal a precious piece of the ship's cargo: a priceless book of ancient mysticism. The Book of Zohar is the first piece of a lethal puzzle that will draw Doyle across the burgeoning young nation. From the filthy slums of lower Manhattan to the dark alleys of Chicago to a final apocalyptic confrontation in the searing Arizona desert, Doyle and his companions track the paths of six mysterious strangers who are united by a single, eerie dream. A dream of a black tower rising out of a wasteland - and a river of blood. As their trails converge at the source of this terrifying vision, Doyle and company confront an evil so dark and profound that it threatens to obliterate the very fabric of the world.
