Biggles becomes involved in four undercover operations in this third bumper omnibus edition of his classic adventure stories that take him from the icy wastes of Antarctica to war-torn Korea. In <I>Biggles’ Second Case</I>, Biggles hunts for a wartime German submarine, the U-517, whose ruthless captain, Von Shonbeck, has escaped to the Antarctic with a horde of stolen gold bullion. In <I>Biggles Breaks the Silence</I>, Biggles is back in the Antarctic once again, tracking down a ship frozen in the pack ice with a hold full of treasure, and doing battle with a gang of desperate villains while attempting to recover the ship’s cargo. In <I>Biggles Gets His Men</I>, Biggles is tasked with the dangerous mission of finding and rescuing a group of important scientists who have been kidnapped and smuggled to a remote region of China. Finally, in <I>Biggles Follows On</I>, Biggles comes up against his arch enemy, Erich Von Stalhein, and teams up with Gimlet King’s special forces unit behind enemy lines in China.
