Triple Spies

The narrative follows Johnny Thompson, a soldier-turned-traveler who becomes entangled with a young Japanese woman and an Eskimo companion while tracking a mysterious sled driver across Siberia's winter wastes. Encounters of disguise, espionage, and violence lead from icy camps and igloos to urban intrigues in Chicago, including deadly confrontations, underworld schemes, a submerged threat in a river, and a puzzling cache of diamonds. Episodes alternate rapid action and investigative puzzles as loyalties shift, identities are revealed, and the protagonists face treachery, narrow escapes, and a three-cornered struggle that resolves the central mysteries.
