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.
Their glances met; Gaspard's eyes glistened in the moonlight. That meeting of glances was but for an instant. The next, Gaspard clapped his hands to the pit of his stomach, and bending over, writhed and twisted and doubled himself in a convulsion of silent, crazy laughter. After a while he straightened himself again, and as Oliver gazed, fascinated, he suddenly began an uncouth, grotesque dance. Around and around he spun, hopping and bobbing up and down; around, around, with his black shadow--pot-bellied, long-limbed, and spider-like--hopping beneath him. So hopping and bobbing, with wagging head and writhing, twisting limbs, he drew nearer and nearer to the door. Another leap, and he had hopped into the house, and the street was silent and deserted once more in the white moonlight.
