White as lightning, her eyes ablaze with hidden fires, her white hands clenched, Roxana straightened herself to her full height, ready to bound at Theodora's throat, to avenge the insult and to settle now and here, woman to woman, the question of supremacy between them, when she reeled as if struck by a thunderbolt. Her hands went to her heart and without a moan she fell, a lifeless heap, upon the floor. Ere Tristan and the other guests could recover from their consternation, or fathom the import of the terrible scene, a savage scream from the couch upon which Fabio reclined, turned the attention of every one in that direction. Fabio, suddenly sobered, had risen from his couch and drained his goblet. It rolled upon the carpet from his nerveless grasp. For a moment his arms wildly beat the air, then he reeled and fell prone upon the floor. His staring eyes and his face, livid with purple spots, proclaimed him dead, even ere the Moorish physician could come to his aid. Theodora clapped her hands, and at the signal four giant Nubians appeared and, taking up the lifeless bodies, disappeared with them in the moonlit garden outside. The Grand Chamberlain, rising from his seat, informed the guests that a sudden ailment had befallen the woman and the man. They were being removed to receive care and attention. Though a lingering doubt hovered in the minds of those who had witnessed the scene, some kept silent through fear, others whose brains were befuddled by the fumes of the wine gave utterance to inarticulate sounds, from which the view they took of the matter, was not entirely clear. The shock had restored to Tristan the lost faculty of speech. For a moment he stared horrified at Theodora. Her impassive calm roused in him a feeling of madness. With an imprecation upon his lips he rushed upon her, his gleaming dagger raised aloft. But ere he could carry out his intent, Theodora's clear, cold voice smote the silence. "Disarm him!" One of the Africans had glided stealthily to his side, and the steel was wrenched from Tristan's grip. "Be silent,--for your life!" some one whispered into his ear. Suddenly he grew weak. Theodora's languid eyes met his own, utterly paralyzing his efforts. A smile parted her lips as, without a trace of anger, she kissed the ivory bud of a magnolia and threw it to him.
