The truth was, as the man said, the detective had gone home to sleep; but no sooner had he lain down than the little traces he had discovered began to excite his imagination, and that faculty, so suggestive in his class, getting inflamed, developed so many images in the camera of his mind, that he soon found sleep an impossibility, and he was now there to know whether anything further had transpired. The men made their report, and he soon saw there was something more than ordinary in Abram's curiosity about the moon, and still more in the coincidence of the visits of Slabberdash and Four-toes. He had a theory, too, about the working, though it did not admit the melting. He knew better what to augur. But he had a fault to find, and he was not slow to find it. "Why didn't one of you track Four-toes? One of you could have served here. She has been off the scene for three weeks, and is hiding. You ought to have known that a woman is a good subject for a detective. Her strength is her weakness, and her weakness our opportunity. But there's no help for it now. We must trace the links we have. If she come again, be more on the alert, and follow up the track. Keep your guard, and let not a circumstance escape you." "The light is out again," remarked one of the men; "he has gone to bed." "But not to sleep, I warrant," said his superior. "Look sharp and listen quick, and I will be with you when I promised." He now proceeded to the office in the High Street, where he found the superintendent waiting for a report in another case. He recounted all he had seen and heard. "You have a chance here," said the latter; "and, to confirm our hopes, I can tell you that Four-toes' mother gave yesterday to a shebeen-master in Toddrick's Close, one of the rings for a mutchkin of whisky; and, what is more, Clinch has been traced to the old woman's house in Blackfriars Wynd. I suspect that the picture's true after all. The cup is verily in Benjamin's sack."
