The Spectral Strangler (1934) – Silent, horrible as the crushing coils of a serpent were those unseen fingers that blotted out men's lives. A criminal of satanic proportions had risen —the "Black Master," whose victims fell with livid, hideous faces and protruding tongues that seemed a ghastly mockery of the fate they had suffered. Along this terrible murder trail Secret Agent "X" gambled with the Dice of Death.
Secret Agent "X" is a master of disguise and his true identity is never revealed. He adopts several different identities in each story. What we do know about "X" is that he served in the War (World War I) in intelligence and was wounded from which he got an X shaped scar. He is a dedicated crime-fighter working undercover for the U.S. government, although this is unknown to local police who consider him an outlaw. His true role is known only to newspaper reporter Betty Dale and his mysterious Washington controller, K-9.
