"The Torture Trust" they called themselves--that unholy trio who met in a hidden room in a deserted part of the city. Brilliant men by day, leading scholarly and productive lives as far as the police and the outside world were concerned, secretly they donned black cloaks and ran an organization of evil ... for "The Torture Trust" threatened their blackmail victims with a terrible acid bath, leaving a trail of faceless corpses to bear mute testimony to their power! Fearless, alone, Secret Agent X went against them in a desperate battle of wits at the gateway to destruction! A classic pulp adventure-mystery, ripped from the pages of the February, 1934 issue of Secret Agent "X" magazine!
