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. Diana's eyes never left the Sheik's face, she felt the old paralysing fear of him rushing over her, irresistibly drowning for the moment even the love she had for him. She had seen him in cruel, even savage moods, but nothing that had ever approached the look of horrible pleasure that was on his face now. It was a revelation of the real man with the thin layer of civilisation stripped from him, leaving only the primitive savage drunk with the lust of blood. And she was afraid, with a shuddering horror, of the merciless, crimson-stained hands that would touch her, of the smiling, cruel mouth that would be pressed on hers, and of the murderous light shining in his fierce eyes. But for the dying wretch expiating his crimes so hideously she felt no pity, he was beyond all sympathy. She had seen him murder wantonly, and she knew what her own fate would have been if Ahmed Ben Hassan had not come. And the retribution was swift. The Sheik was being more merciful to him than the robber chief had been to many, a few moments of agony instead of hours of lingering torture.
