These sounds were heard by still another person—the surgeon's wife; for they originated very near her rooms, which were a considerable distance from her husband's. She had been sleeping lightly, tortured by fear and harassed by frightful dreams. The conspiracy into which she had recently entered, for the destruction of her husband, was a source of great anxiety. She constantly suffered from the most gloomy forebodings, and lived in an atmosphere of terror. Added to the natural horror of her situation were those countless sources of fear which a fright-shaken mind creates and then magnifies. She was, indeed, in a pitiable state, having been driven first by terror to desperation, and then to madness.
Startled thus out of fitful slumber by the noise at her door, she sprang from her bed to the floor, every terror that lurked in her acutely tense mind and diseased imagination starting up and almost overwhelming her. The idea of flight—one of the strongest of all instincts—seized upon her, and she ran to the door, beyond all control of reason. She drew the bolt and flung the door wide open, and then fled wildly down the passage, the appalling hissing and rasping gurgle ringing in her ears apparently with a thousandfold intensity. But the passage was in absolute darkness, and she had not taken a half-dozen steps when she tripped upon an unseen object on the floor. She fell headlong upon it, encountering in it a large, soft, warm substance that writhed and squirmed, and from which came the sounds that had awakened her. Instantly realizing her situation, she uttered a shriek such as only an unnamable terror can inspire. But hardly had her cry started the echoes in the empty corridor when it was suddenly stifled. Two prodigious arms had closed upon her and crushed the life out of her.
The cry performed the office of directing the detective and his assistants, and it also aroused the old surgeon, who occupied rooms between the officers and the object of their search. The cry of agony pierced him to the marrow, and a realization of the cause of it burst upon him with frightful force.
"It has come at last!" he gasped, springing from his bed.
Snatching from a table a dimly-burning lamp and a long knife which he had kept at hand for three years, he dashed into the corridor. The four officers had already started forward, but when they saw him emerge they halted in silence. In that moment of stillness the surgeon paused to listen. He heard the hissing sound and the clumsy floundering of a bulky, living object in the direction of his wife's apartments. It evidently was advancing towards him. A turn in the corridor shut out the view. He turned up the light, which revealed a ghastly pallor in his face.
"Wife!" he called.
There was no response. He hurriedly advanced, the four men following quietly. He turned the angle of the corridor, and ran so rapidly that by the time the officers had come in sight of him again he was twenty steps away. He ran past a huge, shapeless object, sprawling, crawling, and floundering along, and arrived at the body of his wife.
He gave one horrified glance at her face, and staggered away. Then a fury seized him. Clutching the knife firmly, and holding the lamp aloft, he sprang toward the ungainly object in the corridor. It was then that the officers, still advancing cautiously, saw a little more clearly, though still indistinctly, the object of the surgeon's fury, and the cause of the look of unutterable anguish in his face. The hideous sight caused them to pause. They saw what appeared to be a man, yet evidently was not a man; huge, awkward, shapeless; a squirming, lurching, stumbling mass, completely naked. It raised its broad shoulders. It had no head, but instead of it a small metallic ball surmounting its massive neck.
"Devil!" exclaimed the surgeon, raising the knife.
"Hold, there!" commanded a stern voice.
