Harvest of Death — Ramsay Thorne

CAPTAIN GRINGO marches through Mexico!
His destination: hotly disputed cocoa country where men indulge their greed, their lust, and their taste for blood. Captain Gringo's got to slash his way through torrid, twisted jungle crowded with Mexican marauders, greedy guerillas, and ladies with love on their minds. The Captain's always ready to bed young maids or blast away with his Maxim, as magnificent Mayan ruins loom overhead. But when he comes up against a fanatical would-be dictator, it'll take all his American might and mind to explode a brewing international incident in a scorching climax!
