Biggles Buries a Hatchet

News reached Biggles that his greatest enemy, Erich von Stalhein, is imprisoned in an impregnable island fortress behind the Iron Curtain, and Biggles is told that von Stalhein could be the source of some useful information. So with Ginger, Bertie and Algy, he flies to the island of Sakhalin to carry out a rescue operation. Unseen, they get to know the desolate island, and Biggles works out a daring plan to snatch von Stalhein from under the noses of the prison guards.
