Biggles Flies South

Biggles, Algy and Ginger are flying down to Capetown in South Africa for a 266 Squadron Reunion Dinner organised by Major Mullen, Biggles old C.O. Stopping over in Cairo, with plenty of time to spare, they are approached by a young Egyptian called Kadar Alloui Bay. He wants to buy their aeroplane to help in his search for the remains of a lost Persian Army.
