"Perhaps melting," said the other, with a laugh.
"But here comes our officer; there is never rest for that man when there's a bird on the moor or a fox in the covert."
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."
Thus fortified, our detective sought his way again down the High Street; and as he had time to kill between that and the opening of the shutters in Simon Square, he paid a visit to Blackfriars Wynd, where he found his faithful myrmidon keeping watch over the old mother's house, like a Skye terrier at the mouth of a rat-hole. He here learned that Mary with the deficient toe had also been seen to go upstairs to her mother's garret, which circumstance accorded perfectly with the statement of the guard in the square, as no doubt she had returned home after being startled at the door of Abram. But then she was seen to go out again, about an hour before, though whither she went the watch could not say. The hour of appointment was now approaching. The day had broken amidst watery clouds, driven about by a fitful, gusty wind, and every now and then sending stiff showers of rain, sufficient to have cooled the enthusiasm of any one but a hunter after the doers of evil. He had been drenched two or three times, and now he felt that a glass of brandy was necessary as an auxiliary to internal resistance against external aggression. He was soon supplied, and, wending his way to the old rendezvous, he found his guard, but without any addition to their report of midnight. Abram was long of getting up, and it seemed that he was first roused by the clink of a milkwoman's tankard on the window-shutter. The door was slowly opened, but in place of the vendor of milk handing in to her solitary customer the small half-pint, she went in herself, pails, and tankard, and all. Our detective marked the circumstance as being unusual, and, more than unusual still, the door was partly closed upon her as she entered. Then he began to think that she had nothing about her of the appearance of that class of young women.
"Has not that woman the appearance of Four-toes?" said the officer.
