Description
Whilst celebrating Ginger's award of his pilot's licence, an SOS on BBC radio asks for Major James Bigglesworth to contact his uncle, Professor Richard Bigglesworth. This is, of course, Dickpa, previously seen in the story 'The Cruise of the Condor'. Visiting Dickpa at his house, they find him and his friend Lord Roger Maltenham under attack from mysterious enemies.
This story takes Biggles to Tibet before the Chinese occupation.
