He was writhing and tearing at his bonds. Suddenly he broke into a whining unearthly cry, that tailed off into a string of inarticulate blasphemies.

“Officer,” said Gilead whitely: “there’s something beyond what I looked for in this business—something, I believe, infinitely blacker and more deadly. Stay you here while I go over the house.”

The prisoner, straightening himself convulsively, moved as if to spring.

“All right, sir,” said the detective, prompt to interpose. “You can leave him to me.”

Gilead, clipping his little torch into flame, hurried instantly out of the room. A deadly constricted feeling was at his heart; he looked with certainty for some horror to be revealed in a moment. Yet he had no least reason for blaming himself. He had merely watched, not directed, the course of events. Indeed, Providence, it might be said, had appointed in him its unconscious Nemesis. Would only that it had permitted him to forestall in that character the deed he feared.

In the passage he paused an instant to shut and relock the front door, which had remained open from their first entrance. Then he turned to consider his ground. A narrow flight of stairs rose before him; beyond, at the black end of the passage, a second dropped into the basement. He mounted the former in the first instance, his heart beating thickly, and came to a little cluster of rooms, three in all, which revealed nothing but dust and emptiness and peeling wall-paper. Satisfied that they contained, and could contain, no secret, he left them, and, returning to the passage, descended to the basement. He knew now that what he sought, if it existed, must be hidden somewhere here. A sense of something monstrous to be revealed tingled in his veins; stealthy things seemed to rustle and escape before him; at the bottom of the flight he hesitated, momentarily sickened from his quest.

What business was it of his? A bugbear, very likely, of his own fancy! The shock of unforeseen defection in an act of larceny was no doubt sufficient to account for the state of the man above.

A glow came to his face in the darkness. He was glad that heaven and he had been alone together with that shameful thought. He breathed out all his pusillanimity in a great scornful sigh—and the sigh was answered.

He stood a moment as if paralysed. It had been little and tremulous, but unmistakable—an echo, perhaps, of his own. Vaulted darkness gasped at him in front, exhaling a smell of cold flags and cold soot. Close beside him was the near-closed door of the coal-cellar. In a sudden spasm of horror he pushed this open, and, casting his light before him, saw the body of a young girl lying prone upon her back on the stones.

Now a great sorrow and pity came on the instant to nerve him. He bent to look into the bloodless face and saw its eyes closed, its white lips parted; but the nostrils quivered slightly and he knew that she still lived. There was little need to question what had struck her down. High on the bosom of the cheap frock she wore was a crimson splash, and from under her shoulder spread and crawled a black and sluggish little pool.
