S01E01Part One

A relief column led by Major de Beaujolais approaches Fort Zinderneuf, only to find the garrison apparently slaughtered. Legionnaire Digby Geste offers to climb in to investigate, but then seems to disappear himself. The Major enters, and finds a letter grasped in the dead hand of Sergeant-Major Lejaune, mentioning a Lady Brandon, in England. Before investigating further, the fort goes up in flames. Prompted by the letter, de Beaujolais recalls visiting Lady Brandon years earlier, when she was bringing up her three nephews, Digby, John and Michael 'Beau' Geste.
