A master of evil came to the nation's capital. A green-masked ambassador from Hell's own legation, followed by a horrible horde, versed in the poison torments of the Far East! Even the police who sought to trap him, did not guess the ghastliness of his real motive. That remained for Secret Agent "X" to discover, as he prowled through a dark, and sinister labyrinth of Washington espionage.
A nameless mystery man with a wartime past, backed by a shadowy group of powerful philanthropists, Secret Agent "X" took on the toughest assignments of the dirty thirties. Operating out of the half-haunted Montgomery Mansion, "X" was also known as the Man of a Thousand Faces. A past master of disguise, he infiltrated the Underworld to crush crime, in all of its hideous manifestations.
For Secret Agent "X," Rose Wyn decided to pit him against villains who were maestros of unbridled horror. Melodrama was the rule of the day. But Secret Agent "X" plunged into maelstroms of raw bloodlust undreamed of by The Shadow and Doc Savage. His foes were truly depraved. Terrorists. Torturers. Kidnappers. Stranglers. Arsonists. These were the types of tabloid master criminals "X" hunted.
In Ambassador of Doom, the enigmatic "X" travels to Washington, D.C., to investigate skullduggery in our nation's capital. There, he gets on the trail of the Green Mask, a murderous master of espionage, whose ultimate loyalties are impenetrable. Before the trail of treachery has been exhausted, Secret Agent "X" will have struggled through Malay torture rites and worse, in order to preserve America's deepest secrets from an implacable foreign foe.
Ambassador of Doom was originally published in the May, 1934 Secret Agent "X" magazine and is read with chilling intensity by Milton Bagby.
