The Ambassador of Doom

Published in the 05/1934 issue of Secret Agent X.
"A monster 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."
