Don Winslow of the Navy #13

Commander Don Winslow and his friend Red Pennington are captured by Japanese forces after their destroyer is sunk in the Pacific, and find themselves imprisoned near Tokyo Harbor—but the resourceful pair has no intention of staying locked up. With the enemy's subpens in their sights and revenge on their minds, Don and Red engineer a daring escape that turns their captivity into a devastating counterattack against their captors.

Lieutenant "Red" Pennington arrives at Navy College as an instructor and immediately becomes smitten with Jane Smith, the secretary—but when he stumbles upon suspicious activity in his superior's office after hours, he's framed and imprisoned. With help from Don Winslow and a mysterious ally, Red must uncover the real spy operating from within the base before enemy agents silence him for good. This wartime adventure blends romance, intrigue, and action as the truth about Captain Bailey's treachery comes to light.

Don Winslow and Red Pennington go undercover at a Marine canteen to track down who's leaking troop movement information that's getting ships attacked by enemy subs—and their investigation centers on a mysterious hostess working there. When Red agrees to wear a sweater knitted by a young woman named Celeste Carter, Don spots something suspicious about it, launching a dangerous operation that puts Red in the hands of enemy spies. It's a wartime mystery where a seemingly innocent piece of clothing becomes the key to uncovering sabotage and espionage.

Don Winslow and Red are assigned to Coast Guard duty on the Great Lakes, where merchant ships carrying vital American iron ore are being mysteriously torpedoed—but no submarine can be found. As Don investigates the impossible attacks, he uncovers a shocking Nazi plot hidden along the shoreline, leading him to a discovery that challenges everything they thought they knew about how the enemy is striking from within America's heartland. With the next ore-ship in danger and the clock ticking, Don must infiltrate the source of the attacks before more vessels are sent to the bottom.
