She looked down for a moment thoughtfully at the dim shape of the hound lying at the man's feet, and then with a last upward glance at the bright stars turned back into the tent. All her nervous fears had vanished in speaking to Gaston, who was the embodiment of practical common sense; earlier, when unreasoning terror had taken such a hold on her, she had forgotten that he was within call, faithful and devoted. She picked up the fallen book, and lying down again forced herself to read, but though her eyes followed the lines mechanically she did not sense what she was reading, and all the time her ears were strained to catch the earliest sound of his coming.

At last it came. Only a suggestion at first—a wave of thought caught by her waiting brain, an instinctive intuition, and she started up tense with expectancy, her lips parted, her eyes wide, hardly breathing, listening intently. And when he came it was with unexpected suddenness, for, in the darkness, the little band of horsemen were invisible until they were right on the camp, and the horses' hoofs made no sound. The stir caused by his arrival died away quickly. For a moment there was a confusion of voices, a jingle of accoutrements, one of the horses whinnied, and then in the ensuing silence she heard him come into the tent. Her heart raced suffocatingly. There was a murmur of conversation, the Sheik's low voice and Gaston's quick animated tones answering him, and then the servant hurried out. Acutely conscious of every sound, she waited motionless, her hands gripping the soft mattress until her fingers cramped, breathing in long, painful gasps as she tried to stop the laboured beating of her heart. In spite of the heat a sudden coldness crept over her, and she shivered violently from time to time. Her face was quite white, even her lips were colourless and her eyes, fixed on the curtain which divided the two rooms, glittered feverishly. With her intimate knowledge every movement in the adjoining room was as perceptible as if she had seen it. He was pacing up and down as he had paced on the night when Gaston's fate was hanging in the balance, as he always paced when he was deliberating anything, and the scent of his cigarette filled her room. Once he paused near the communicating curtain and her heart gave a wild leap, but after a moment he moved away. He stopped again at the far end of the tent, and she knew from the faint metallic click that he was loading his revolver. She heard him lay it down on the little writing-table, and then the steady tramping began once more. His restlessness made her uneasy. He had been in the saddle since early dawn. Saint Hubert had advised him to be careful for some weeks yet. It was imprudent not to rest when opportunity offered. He was so careless of himself. She gave a quick, impatient sigh, and the tender light in her eyes deepened into an anxiety that was half maternal. In spite of his renewed strength and his laughing protests at Raoul's warnings, coupled with a physical demonstration on his less muscular friend that had been very conclusive, she could never forget that she had seen him lying helpless as a child, too weak even to raise his hand. Nothing could ever take the remembrance from her, and nothing could ever alter the fact that in his weakness he had been dependent on her. She had been necessary to him then. She had a moment's fierce pleasure in the thought, but it faded as suddenly as it had come. It had been an ephemeral happiness.

At last she heard the divan creak under his weight, but not until Gaston came back bringing his supper. As he ate he spoke, and his first words provoked an exclamation of dismay from the Frenchman, which was hastily smothered with a murmured apology, and then Diana became aware that others had come into the room. He spoke to each in turn, and she recognised Yusef's clear, rather high-pitched voice arguing with the taciturn head camelman, whose surly intonations and behaviour matched the bad-tempered animals to whom he was devoted, until a word from Ahmed Ben Hassan silenced them both. There were two more who received their orders with only a grunt of acquiescence.

Presently they went out, but Yusef lingered, talking volubly, half in Arabic, half in French, but lapsing more and more into the vernacular as he grew excited. Even in the midst of her trouble the thought of him sent a little smile to Diana's lips. She could picture him squatting before the Sheik, scented and immaculate, his fine eyes rolling, his slim hands waving continually, his handsome face alight with boyish enthusiasm and worship. At last he, too, went, and only Gaston remained, busy with the cafetiere that was his latest toy. The aroma of the boiling coffee filled the tent. She could imagine the servant's deft fingers manipulating the fragile glass and silver appliance. She could hear the tinkle of the spoon as he moved the cup, the splash of the coffee as he poured it out, the faint sound of the cup being placed on the inlaid table. Why was Ahmed drinking French coffee when he always complained it kept him awake? At night he was in the habit of taking the native preparation. Surely to-night he had need of sleep. It was the hardest day he had had since his illness. For a few moments longer Gaston moved about the outer room, and from the sound Diana guessed that he was collecting on to a tray the various things that had to be removed. Then his voice, louder than he had spoken before:

"Monseigneur desir d'autre chose?"

The Sheik must have signed in the negative, for there was no audible answer.

"Bon soir, Monseigneur."

"Bon soir, Gaston."

Diana drew a quick breath. While the man was still in the adjoining room the moment for which she was waiting seemed interminable. And now she wished he had not gone. He stood between her and—what? For the first time since the coming of Saint Hubert she was alone with him, really alone. Only a curtain separated them, a curtain that she could not pass. She longed to go to him, but she did not dare. She was pulled between love and fear, and for the moment fear was in the ascendant. She shivered, and a sob rose in her throat as the memory came to her of another night during those two months of happiness, that were fast becoming like a wonderful dream, when he had ridden in late. After Gaston left she had gone to him, flushed and bright-eyed with sleep, and he had pulled her down on to his knee, and made her share the native coffee she detested, laughing boyishly at her face of disgust. And, holding her in his arms with her head on his shoulder, he had told her all the incidents of the day's visit to one of the other camps, and from his men and his horses drifted almost insensibly into details connected with his own plans for the future, which were really the intimate confidences of a husband to a wife who is also a comrade. The mingled pain and pleasure of the thought had made her shiver, and he had started up, declaring that she was cold, and, lifting her till his cheek was resting on hers, carried her back into the other room.

But what she had done then was impossible now. He seemed so utterly strange, so different from the man whom she thought she had grown to understand. She was all at sea. She was desperately tired, her head aching and confused with the terrible problems of the future. She dared not think any more. She only wanted to lie in his arms and sob her heart out against his. She was starving for the touch of his hands, suffering horribly.
