Biggles: The Cruise of the Condor - Captain W. E. Johns

The Great War is over, and Biggles is bored. The adrenaline-pounding thrill of flying over the trenches seems a lifetime ago. When he receives word that his uncle is back in the country from his own adventures, Biggles takes Algy along to visit him.

But Biggles’ uncle is in a spot of hot water. While he was exploring in Brazil, he found himself on the trail of a long-lost treasure. But, before he could locate it, his treacherous porters turned against him, tracked him back to England, and now have him under siege in his own house.

Biggles is not going to let this stand. Together, he and Algy help him break out. There is only one thing to do: fly back to Brazil, and be the first ones to find the treasure.

A perilous quest to the heart of the Amazon awaits our heroes, where danger lurks around every corner…
