Death over Darien — Ramsay Thorne

Captain Gringo spearheads a red-hot war in Panama!
Even when he is minding his own business, trouble seeks out Captain Gringo. This time the British Secret Service is on his back, seeking information on a Scottish pearl­ trading colony on the Caribbean coast. Gringo's in the dark as well- until a voluptuous redhead lures him into her bedroom to show him her collection of exotic pearls. From there it becomes a real knockaround time for the big Yankee soldier of fortune, fending off Carib gals and Scottish lassies, fighting a land-grabbing Spanish grandee and his death-dealing - and battling British imperialists who want to bring the pearl-rich colony to its knees!
