Fight against Crime #7

A foreign power recruits racket boss Harry "Gassy" Webb to steal a secret anti-gas formula from Professor Frederick Holt by threatening Webb's daughter Eileen. After locating Holt in Mexico, Webb obtains the formula, but FBI agent Harry trails him. Webb uses poison gas on Holt and attempts to escape by plane, but the FBI closes in and kills both Webb and Holt during the pursuit, ultimately recovering the stolen formula.
