The secret diaries of John Patrick Scott pick up at the close of 1917. British intelligence sends Scott to work undercover in Berlin with his old partner-in-crime, Wendell Mackenzie, as his outside contact in Paris. Back on the Western Front, Scott discovered his ability to see the ghosts of the dead. Unsure if that's a blessing or a curse, he takes this one-step further, employing spirits in the world of deception and intrigue. As the Russian monarchy crumbles and the Red Baron meets his final match, for Scott, true love is always beyond arm's reach. His long-lost patrons and paramours, Sophia and Francois Poincaré, resurface but as potential enemies of the Crown.

Arthur Conan Doyle vows to retrieve his stolen time machine from H.G. Wells. Scott is still at odds with Doyle, who still refuses to publicly acknowledge his contributions for ghostwriting Sherlock Holmes, and Doyle encounters Harry Houdini in the most unlikely of places. Get ready for a wild ride. Time Traveler Professor, Book Three: A War in Too Many Worlds, pairs murder, mayhem and mysticism in a mashup where The Lost World meets The Hound of the Baskervilles and The Island of Doctor Moreau.
