Richard Wentworth — whose grim, anti-crime crusades as the Spider have made him world-famous — was the first objective in the Poison Master’s murder campaign. His best friend, Kirkpatrick, lay in a death-like stupor. His beloved, Nita van Sloan, was stricken with the horrible living death! And at the same time, countless thousands were felled by the same fatal venom... Caught in the crossfire between the Law and the Underworld, the Spider must battle the blind apathy of a nation ensnared in a subtle death-trap — must overcome the despair in his own brave heart...! Laboratory of the Damned is torn from the pages of the July, 1936 issue of The Spider magazine.
