To Diana before she had come to Africa the life of an Arab Sheik in his
native desert had been a very visionary affair. The term sheik itself
was elastic. She had been shown Sheiks in Biskra who drove hard
bargains to hire out mangy camels and sore-covered donkeys for trips
into the interior. Her own faithless caravan-leader had called himself
"Sheik." But she had heard also of other and different Sheiks who lived
far away across the shimmering sand, powerful chiefs with large
followings, who seemed more like the Arabs of her imaginings, and of
whose lives she had the haziest idea. When not engaged in killing their
neighbours she visualized them drowsing away whole days under the
influence of narcotics, lethargic with sensual indulgence. The pictures
she had seen had been mostly of fat old men sitting cross-legged in the
entrance of their tents, waited on by hordes of retainers, and looking
languidly, with an air of utter boredom, at some miserable slave being
beaten to death.

She had not been prepared for the ceaseless activity of the man whose
prisoner she was. His life was hard, strenuous and occupied. His days
were full, partly with the magnificent horses that he bred, and partly
with tribal affairs that took him from the camp for hours at a time.
Upon one or two occasions he had been away for the whole night and had
come back at daybreak with all the evidences of hard riding. Some days
she rode with him, but when he had not the time or the inclination, the
French valet went with her. A beautiful grey thoroughbred called Silver
Star was kept for her use, and sometimes on his back she was able to
forget for a little time. So the moments of relaxation were less
frequent than they might have been, and it was only in the evenings
when Gaston had come and gone for the last time and she was alone with
the Sheik that an icy hand seemed to close down over her heart. And,
according to his mood, he noticed or ignored her. He demanded implicit
obedience to his lightest whim with the unconscious tyranny of one who
had always been accustomed to command. He ruled his unruly followers
despotically, and it was obvious that while they loved him they feared
him equally. She had even seen Yusef, his lieutenant, cringe from the
heavy scowl that she had, herself, learned to dread.
