David got slowly to his feet and turned towards the monastery. The figure of a monk stood in the doorway with a torch to light him to his room.

He turned to Ebn Ezra again. "Does thee think that I have aught of his courage—my Uncle Benn? Thou knowest me—shall I face it out as did he?"

"Saadat," the old man answered, pointing, "yonder acacia, that was he, quick to grow and short to live; but thou art as this date-palm, which giveth food to the hungry, and liveth through generations. Peace be upon thee," he added at the doorway, as the torch flickered towards the room where David was to lie.

"And upon thee, peace!" answered David gently, and followed the smoky light to an inner chamber. The room in which David found himself was lofty and large, but was furnished with only a rough wooden bed, a rug, and a brazier. Left alone, he sat down on the edge of the bed, and, for a few moments, his mind strayed almost vaguely from one object to another. From two windows far up in the wall the moonlight streamed in, making bars of light aslant the darkness.

Not a sound broke the stillness. Yet, to his sensitive nerves, the air seemed tingling with sensation, stirring with unseen activities. Here the spirit of the desert seemed more insistent in its piercing vitality, because it was shut in by four stone walls.

Mechanically he took off his coat, and was about to fold and lay it on the rug beside the bed, when something hard in one of the pockets knocked against his knee. Searching, he found and drew forth a small bottle which, for many a month past, had lain in the drawer of a table where he had placed it on his return from the Soudan. It was an evil spirit which sent this tiny phial to his hand at a moment when he had paid out of the full treasury of his strength and will its accumulated deposit, leaving him with a balance on which no heavy draft could be made. His pulse quickened, then his body stiffened with the effort at self-control.

Who placed this evil elixir in his pocket? What any enemy of his work had done was nothing to what might be achieved by the secret foe, who had placed this anodyne within his reach at this the most critical moment of his life. He remembered the last time he had used it—in the desert: two days of forgetfulness to the world, when it all moved by him, the swarming Arabs, the train of camels, the loads of ivory, the slimy crocodile on the sandbanks, the vultures hovering above unburied carcasses, the kourbash descending on shining black shoulders, corrugating bare brown bodies into cloven skin and lacerated flesh, a fight between champions of two tribes who clasped and smote and struggled and rained blows, and, both mortally wounded, still writhed in last conflict upon the ground—and Mahommed Hassan ever at the tent door or by his side, towering, watchful, sullen to all faces without, smiling to his own, with dog-like look waiting for any motion of his hand or any word…. Ah, Mahommed Hassan, it was he! Mahommed had put this phial in his pocket. His bitter secret was not hidden from Mahommed. And this was an act of supreme devotion—to put at his hand the lulling, inspiring draught. Did this fellah servant know what it meant—the sin of it, the temptation, the terrible joy, the blessed quiet; and then, the agonising remorse, the withering self-hatred and torturing penitence? No, Mahommed only knew that when the Saadat was gone beyond his strength, when the sleepless nights and feverish days came in the past, in their great troubles, when men were dying and only the Saadat could save, that this cordial lifted him out of misery and storm into calm. Yet Mahommed must have divined that it was a thing against which his soul revolted, or he would have given it to him openly. In the heart and mind of the giant murderer, however, must have been the thought that now when trouble was upon his master again, trouble which might end all, this supreme destroyer of pain and dark memory and present misery, would give him the comfort he needed—and that he would take it.

If he had not seen it, this sudden craving would not have seized him for this eager beguiling, this soothing benevolence. Yet here it was in his hand; and even as it lay in his cold fingers—how cold they were, and his head how burning!—the desire for it surged up in him. And, as though the thing itself had the magical power to summon up his troubles, that it might offer the apathy and stimulus in one—even as it lured him, his dangers, his anxieties, the black uncertainties massed, multiplied and aggressive, rose before him, buffeted him, caught at his throat, dragged down his shoulders, clutched at his heart.

Now, with a cry of agony, he threw the phial on the ground, and, sinking on the bed, buried his face in his hands and moaned, and fought for freedom from the cords tightening round him. It was for him to realise now how deep are the depths to which the human soul can sink, even while labouring to climb. Once more the sense of awful futility was on him: of wasted toil and blenched force, veins of energy drained of their blood, hope smitten in the way, and every dear dream shattered. Was it, then, all ended? Was his work indeed fallen, and all his love undone? Was his own redemption made impossible? He had offered up his life to this land to atone for a life taken when she—when she first looked up with eyes of gratitude, eyes that haunted him. Was it, then, unacceptable? Was it so that he must turn his back upon this long, heart-breaking but beloved work, this panacea for his soul, without which he could not pay the price of blood?

Go back to England—to Hamley where all had changed, where the old man he loved no longer ruled in the Red Mansion, where all that had been could be no more? Go to some other land, and there begin again another such a work? Were there not vast fields of human effort, effort such as his, where he could ease the sorrow of living by the joy of a divine altruism? Go back to Hamley? Ah, no, a million times, no! That life was dead, it was a cycle of years behind him. There could be no return. He was in a maelstrom of agony, his veins were afire, his lips were parched. He sprang from his bed, knelt down, and felt for the little phial he had flung aside. After a moment his hand caught it, clutched it. But, even at the crest of the wave of temptation, words that he had heard one night in Hamley, that last night of all, flashed into his mind—the words of old Luke Claridge's prayer, "And if a viper fasten on his hand, O Lord—"
