Assault on a Queen

When treasure hunters in the Caribbean come across a sunken U-Boat they also find that it was scuttled by its captain and is more or less intact. Eric Lauffnauer is a former World War II U-Boat captain and American Mark Brittain served on subs in the Pacific. Lauffner proposes they give up their treasure hunt and instead turn to piracy - in a few days time the RMS Queen Mary will be in the area with millions of dollars of cash, gold and jewels in its strong room.
