The Last Voyage of the Paramaribo Queen (A Rick Kasten Espionage Novel)

The once an amateur spy, now turned professional, Rick is being sent back into the heart of Nazi Germany to torpedo Doenitz's plans and find the men who murdered his Aurelia. 
The Last Voyage of the Paramaribo Queen sets a stormy course from New York to Lisbon and across the Atlantic to the tranquil Caribbean. But that tranquility is deceptive and short-lived, U-Boats and spies abound on the lush tropical coast of South America. Once again, Rick Kasten finds himself pitted against modern-day pirates who ply the waters of the Spanish Main in search of the black gold that fuels modern warfare.
