First Edition. Nautical adventure. "Sunken treasure is one of the most alluring subjects of tales of adventure, and here is an irresistible one brought down to the minute by a master of the art, for the time is just after the great war, the treasure is in a ship sunk during the war, and the method of recovery is a converted submarine. The story is told by a young American shipmaster who had commanded one of his own vessels, had many adventures, and met his ideal girl, in wartime." Near Fine in Good only dustjacket, lacking lower two and half inches of spine, two inch deep chip at lower front panel.
