There was a pause, a silence that contrasted oddly with the tumult outside, and Diana wondered numbly why the Sheik did nothing, why he did not use the revolver that was clenched in his hand Then slowly she understood that he dared not fire, that the chief was holding her, a living shield, before him, sheltering himself behind the only thing that would deter Ahmed Ben Hassan's unerring shots. Cautiously Ibraheim Omair moved backward, still holding her before him, hoping to gain the inner room. But in the shock of his enemy's sudden appearance he miscalculated the position of the divan and stumbled against it, losing his balance for only a moment, but long enough to give the man whose revolver covered him the chance he wanted. With the cold ring of steel pressing against his forehead the robber chief's hands dropped from Diana, and she slid weak and trembling on to the rug, clasping her pulsating throat, moaning with the effort that it was to breathe.
For a moment the two men looked into each other's eyes and the knowledge of death leaped into Ibraheim Omair's. With the fatalism of his creed he made no resistance, as, with a slow, terrible smile, the Sheik's left hand reached out and fastened on his throat. It would be quicker to shoot, but as Diana had suffered so should her torturer die. All the savagery in his nature rose uppermost. Beside the pitiful, gasping little figure on the rug at his feet there was the memory of six mutilated bodies, his faithful followers, men of his own age who had grown to manhood with him, picked men of his personal bodyguard who had been intimately connected with him all his life, and who had served him with devotion and unwavering obedience. They and others who had from time to time fallen victims to Ibraheim Omair's hatred of his more powerful enemy. The man who was responsible for their deaths was in his power at last, the man whose existence was a menace and whose life was an offence, of whose subtleties he had been trained from a boy to beware by the elder Ahmed Ben Hassan, who had bequeathed to him the tribal hatred of the race of whom Ibraheim Omair was head, and whose dying words had been the wish that his successor might himself exterminate the hereditary enemy. But far beyond the feelings inspired by tribal hatred or the remembrance of the vow made five years ago beside the old Sheik's deathbed, or even the death of his own followers, was the desire to kill, with his bare hands, the man who had tortured the woman he loved. The knowledge of her peril, that had driven him headlong through the night to her aid, the sight of her helpless, agonised, in the robber chief's hands, had filled him with a madness that only the fierce joy of killing would cure. Before he could listen to the clamouring of the new love in his heart, before he could gather up into his arms the beloved little body that he was yearning for, he had to destroy the man whose murders were countless and who had at last fallen into his hands.
The smile on his face deepened and his fingers tightened slowly on their hold. But with the strangling clasp of Ahmed Ben Hassan's hands upon him the love of life waked again in Ibraheim Omair and he struggled fiercely. Crouched on the floor Diana watched the two big figures swaying in mortal combat with wide, fearful eyes, her hands still holding her aching throat. Ibraheim Omair wrestled for his life, conscious of his own strength, but conscious also of the greater strength that was opposed to him. The Sheik let go the hold upon his throat and with both arms locked about him manoeuvred to get the position he required, back to the divan. Then, with a wrestler's trick, he swept Ibraheim's feet from under him and sent his huge body sprawling on to the cushions, his knee on his enemy's chest, his hands on his throat. With all his weight crushing into the chief's breast, with the terrible smile always on his lips, he choked him slowly to death, till the dying man's body arched and writhed in his last agony, till the blood burst from his nose and mouth, pouring over the hands that held him like a vice.
