"You could, but you will not, Ahmed," replied the Vicomte, with an accent of regret. "It is not worthy of you." He paused and then looked up again with a little crooked smile and a shrug of defeat. "Nothing can ever make any difference with us, Ahmed. I can disagree with you, but I can't wipe out the recollection of the last twenty years."

A few minutes later the Sheik left him and went out into the night. He traversed the short distance between the tents slowly, stopping to speak to a sentry, and then pausing outside his own tent to look up at the stars. The Persian hound that always slept across the entrance uncurled himself and got up, thrusting a wet nose into his hand. The Sheik fondled the huge creature absently, stroking the dog's shaggy head mechanically, hardly conscious of what he was doing. A great restlessness that was utterly foreign to his nature had taken possession of him. He had been aware of it growing within him for some time, becoming stronger daily, and now the coming of Raoul de Saint Hubert seemed to have put the crowning touch to a state of mind that he was unable to understand. He had never been given to thinking of himself, or criticising or analysing his passing whims and fancies. All his life he had taken what he wanted; nothing on which he had ever laid eyes of desire had been denied him. His wealth had brought him everything he had ever wished. His passionate temper had been characteristic even when he was a child, but these strange fits of unreasonable irritability were new, and he searched for a cause vainly. His keen eyes looked through the darkness towards the south. Was it the nearness of his hereditary enemy, who had presumed to come closer than he had ever done before to the border of the country that Ahmed Ben Hassan regarded as his own, that was causing this great unrest? He laughed contemptuously. Nothing would give him greater pleasure than coming into actual collision with the man whom he had been trained from boyhood to hate. As long as Ibraheim Omair remained within his own territory Ahmed Ben Hassan held his hand and kept in check his fierce followers, whose eyes were turned longingly towards the debatable land, but once let the robber Sheik step an inch over the border, and it was war, and war until one or both of the chiefs were dead. And if he died who had no son to succeed him; the huge tribe would split up in numerous little families for want of a leader to keep them together, and it would be left to the French Government to take over, if they could, the vast district that he had governed despotically. And at the thought he laughed again. No, it was not Ibraheim Omair who was troubling him. He pushed the hound aside and went into the tent. The divan where Diana had been sitting was strewn with magazines and papers, the imprint of her slender body still showed in the soft, heaped-up cushions, and a tiny, lace-edged handkerchief peeped out under one of them. He picked it up and looked at it curiously, and his forehead contracted slowly in the heavy black scowl. He turned his burning eyes toward the curtains that divided the rooms. Saint Hubert's words rang in his ears. "English!" he muttered with a terrible oath. "And I have made her suffer as I swore any of that damned race should if they fell into my hands. Merciful Allah! Why does it give me so little pleasure?"

CHAPTER VII

Diana came into the living-room one morning about a week after the arrival of the Vicomte de Saint Hubert. She had expected to find the room empty, for the Sheik had risen at dawn and ridden away on one of the distant expeditions that had become so frequent, and she thought his friend had accompanied him, but as she parted the curtains between the two rooms she saw the Frenchman sitting at the little writing-table surrounded by papers and writing quickly, loose sheets of manuscript littering the floor around him. It was the first time that they had chanced to be alone, and she hesitated with a sudden shyness. But Saint Hubert had heard the rustle of the curtain, and he sprang to his feet with the courteous bow that proclaimed his nationality.

"Your pardon, Madame. Do I disturb you? Tell me if I am in the way. I am afraid I have been very untidy," he added, laughing apologetically, and looking at the heap of closely-written sheets strewing the rug.

Diana came forward slowly, a faint colour rising in her face. "I thought you had gone with Monseigneur."

"I had some work to do—some notes that I wanted to transcribe before I forgot myself what they meant; I write vilely. I have had a hard week, too, so I begged a day off. I may stay? You are sure I do not disturb you?"

His sympathetic eyes and the deference in his voice brought an unexpected lump into her throat. She signed to him to resume his work and passed out under the awning. Behind the tent the usual camp hubbub filled the air. A knot of Arabs at a little distance were watching one of the rough-riders schooling a young horse, noisily critical and offering advice freely, undeterred by the indifference with which it was received. Others lounged past engaged on the various duties connected with the camp, with the Eastern disregard for time that relegated till to-morrow everything that could possibly be neglected to-day. Near her one of the older men, more rigid in his observances than the generality of Ahmed Ben Hassan's followers, was placidly absorbed in his devotions, prostrating himself and fulfilling his ritual with the sublime lack of self-consciousness of the Mohammedan devotee.

Outside his own tent the valet and Henri were sitting in the sun, Gaston on an upturned bucket, cleaning a rifle, and his brother stretched full length on the ground, idly flapping at the flies with the duster with which he had been polishing the Vicomte's riding-boots. Both men were talking rapidly with frequent little bursts of gay laughter. The Persian hound was lying at their feet. He raised his head as Diana appeared, and, rising, went to her slowly, rearing up against her with a paw on each shoulder, making clumsy efforts to lick her face, and she pushed him down with difficulty, stooping to kiss his shaggy head.

She looked away across the desert beyond the last palms of the oasis. A haze hung round about, shimmering in the heat and blurring the outline of the distant hills. A tiny breeze brought the acrid smell of camels closer to her, and the creaking whine of the tackling over the well sounded not very far away. Diana gave a little sigh. It had all grown so familiar. She seemed to have lived no other life beside this nomad existence. The years that had gone before faded into a kind of dim remembrance, the time when she had travelled ceaselessly round the world with her brother seemed very remote. She had existed then, filling her life with sport, unconscious of the something that was lacking in her nature, and now she was alive at last, and the heart whose existence she had doubted was burning and throbbing with a passion that was consuming her. Her eyes swept lingeringly around the camp with a very tender light in them. Everything she saw was connected with and bound up in the man who was lord of it all. She was very proud of him, proud of his magnificent physical abilities, proud of his hold over his wild turbulent followers, proud with the pride of primeval woman in the dominant man ruling his fellow-men by force and fear.
