The houses across the way stood black and silent against the pale moonlit sky behind. The street between was bathed in the white glamour. In the middle of it and facing the house stood the motionless figure of a woman wrapped in the folds of a long black cloak. Just below Oliver was the window that he had heard softly raised a moment since, and out of it a head was looking. Oliver could only see the back of the head, but he knew very well that it was the American uncle's. He must have made some noise, for the head suddenly turned and looked up. He drew back with a keen thrill, afraid—but not knowing why he was afraid—of being seen. For a while he stood waiting and listening with bated breath and a beating heart, but all was silent below. Then again he peeped cautiously out over the window-sill; the head below was gone now, but the silent, motionless figure in the street was yet there.

"AT THAT MOMENT SHE LOOKED UP."

At that moment she looked up, and Oliver saw her face. It was beautiful, but as livid as death; just such a face as might utter the sound that had awakened him to his blind terror. The eyes were fixed upon him, but not as though they saw him, and he leaned far out of the window, gazing fascinated. Presently the thin lips parted, he saw the white teeth glitter in the moonlight, and for the third time he heard that quavering, unearthly wail break out upon the night.

Suddenly the door of the house beneath opened noiselessly, and two figures stepped out into the pale glamour. One was the American uncle, the other was the clever servant Gaspard. The latter carried over his arm something that looked like a long black cloak. At their coming the sound instantly ceased, and the woman slowly turned her white ghostly face towards them. The American uncle strode up to her and caught her fiercely by the wrist, but she moved no more than if she had been dead. Oliver saw the American uncle stand looking this way and that, like one seeking for some escape; then he looked at Gaspard. The clever servant was mouthing and grimacing in a horrible, grotesque manner. Oliver could see him as plain as day, for the white moonlight shone full in his lean grisly face. He opened what he carried upon his arm; it was a long, black, bag-like hood.

Once again the tremulous, wailing cry cut through the night, at first faint, then rising higher and higher and clearer and clearer. Oliver saw his uncle shudder. Gaspard grinned; he crouched together, and held the black bag open in his hands. Oliver heard the American uncle utter a sharp word that he could not understand, and saw him fling the wrist he held away from him.

What next passed happened in an instant. There was a leap, a swift, silent, horrible struggle, and the sound was stilled. Gaspard had drawn the black bag over the woman's head and shoulders. Then, without pausing an instant, he picked her up, flung her limp and helpless form over his shoulder like a sack of grain, turned, and with noiseless feet ran swiftly down the street. Oliver watched him as he ran into an inky shadow, flitted across a patch of moonlight, disappeared in a shadow again, appeared, disappeared, was gone. "My God!" he muttered to himself; "the bridge and the river are down there. Would he—"

When he looked again he saw that his uncle had gone back into the house.

For a long time the street below lay deserted in the silence of the moonlight. In the stillness Oliver could hear the far-away sound of running water and the distant barking of a dog. He leaned against the side of the window, watching with fascinated interest for the return of the serving-man. At last he thought that he saw a movement far down upon the moonlit street. It was Gaspard returning, without his burden. He appeared, disappeared, passed through the silent blocks of shadow, of moonlight, of shadow, with the same swift, noiseless steps, until he reached the road in front of the house. Then he stopped short; there was a momentary pause, and then he looked quickly and suddenly up. It was the face of a grinning devil from hell that Oliver saw.
