The Green Mask #5

The Green Mask and his partner Domino battle spies working for an enemy power who possess stolen secrets. After the Green Mask destroys the spies' evidence, he pursues them to an airfield where a plane crash occurs; the villain Hans Funkel is revealed to be responsible for deaths and is operating an airplane factory where plans are made to plant bombs. The issue also includes a separate story, "Chen Chang," in which the villainous Chinese character Chen Chang plots against the white race, and a wagon carrying munitions is destroyed when it crashes into a dump.
