There was some excuse for this piece of folly. He was newly married. He adored his wife, and she worshipped him, and refused to let him go unless she went also.

She was barely half his age; a girl just fresh from a convent school, whom he had met and married in Paris during his last leave.

Colonel Le Breton journeyed for weeks through an arid country, an almost trackless expanse of poor grass and stunted scrub, until he reached the edge of the Sahara.

Annette Le Breton enjoyed her travels. She did not mind the life in tents, the rough jolting of her camel, the poor food, the heat, the flies; she minded nothing so long as she was with her husband. He was a man of rare fascination, as many women had found to their cost; a light lover until Annette had come into his life and captured his straying heart once and for all.

On the edge of the Sahara Le Breton met a man who, on the surface at least, appeared to see even more quickly than the majority of negro kings and Arab chiefs he had come in contact with, the advantages attached to being under the shadow of the French flag.

It would be difficult to say where the Sultan Casim Ammeh came from. He appeared one afternoon riding like a madman out of the blazing distance; a picturesque figure in his flowing white burnoose, sitting his black stallion like a centaur.

He was a young man, perhaps about twenty-four, of medium height, lean and lithe and brown, with fierce black eyes and a cruel mouth: the hereditary ruler of that portion of the Sahara. His capital was a walled city that, so far, had not been visited by any European. In his way he was a man of great wealth, and he added to that wealth by frequent marauding expeditions and slave-dealing.

With a slight smile he listened to all the Frenchman had to say. Already he had heard of France—a great Power, creeping slowly onwards—and he wondered whether he was strong enough to oppose it, or whether the wiser plan might not be just to rest secure under the shadow of its distant wing, and under its protection continue his wild, marauding life as usual.

As he sat with Colonel Le Breton in the latter's tent, something happened which caused the Sultan Casim Ammeh to make up his mind very quickly.

It was late afternoon. From the open flap of the tent an endless, rolling expense of sand showed, with here and there a knot of coarse, twisted grass, a dwarfed shrub, or a flare of red-flowered, distorted cacti. The French officer's camp was pitched by an oasis; a little group of date palms, where a spring bubbled among brown rocks, bringing an abundance of grass and herbs where horses and camels browsed.
