Volcano of Violence — Ramsay Thorne

Captain Gringo in a gunman's graveyard in Guatamala!
The curvaceous blonde twins named Flora and Dora need a troubleshooter to “shoot some trouble.” Gringo's their man -- in more ways that one -- only now these two luscious lovelies have got him trapped between the Mexican army on one side and the black-hearted rebel leader El Caballero Blanco on the other. But even worse, Gringo is boxed in next to a lava-spewing volcano! The molten rock is hot, all right -- but not nearly so hot as the nympho nurse who really knows how to make a man's temperature rise!
