In this, the debut of Secret Agent "X", the Agent must match wits with a coterie of criminals that uses torture and murder to extract ransoms from prominent figures.
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.
The Torture Trust (1934)
Men with skulls for faces—these were the victims of that terrible trio who met in a hidden room. And Secret Agent "X" went against them, daring the bottled torment of their deaf-mute slaves, in a desperate battle of wits at the gateway of destruction.
