With his powerful grasp still on the underling's collar, Mr. Grimstone walked out of the market-place, neither looking to the right nor the left, though many a pair of rustic eyes opened to their widest as he passed, attracted no doubt by the rapidity of his pace and the obvious determination of his manner. Perhaps those rustic bystanders thought that the stern-looking gentleman in the black frock-coat had arrested the shabby little man in the act of picking his pocket, and was bearing him off to deliver him straight into the hands of justice.

Mr. Grimstone released his grasp when he and his companion had got clear of the market-place.

"Now," he said, breathless, but not slackening his pace,—"now I suppose you can tell me how you came to make such an"—inadmissable adjective—"fool of yourself? Never you mind where I'm goin'. I'm goin' to the railway station. Never you mind why I'm goin' there. You'd guess why, if you weren't a fool. Now tell me all about it, can't you?"

"It aint much to tell," the humble follower gasped, his respiratory functions sadly tried by the pace at which his superior went over the ground. "It aint much. I followed your instructions faithful. I tried, artful and quiet-like, to make acquaintance with him; but that warn't a bit o' good. He was as surly as a bull-terrier, so I didn't force him to it; but kept an eye upon him, and let out before him as it was racin' business as had brought me to Doncaster, and as I was here to look after a horse, what was in trainin' a few miles off, for a gent in London; and when he left the public, I went after him, but not conspicuous. But I think from that minute he was fly, for he didn't go three steps without lookin' back, and he led me such a chase as made my legs tremble under me, which they trembles at this moment; and then he gets me into the market-place, and he dodges here, and he dodges there, and wherever the crowd's thickest he dodges most, till he gets me at last in among a ring of market-people round a couple o' coves a-millin' with each other, and there I loses him. And I've been in and out the market, and here and there, until I'm fit to drop, but it aint no good; and you've no call to lay the blame on me, for mortal man couldn't have done more."

Mr. Chivers wiped the perspiration from his face in testimony of his exertions. Dirty little streams were rolling down his forehead and trickling upon his poor faded cheeks. He mopped up these evidences of his fatigue with a red cotton handkerchief, and gave a deprecatory sigh.

"If there's anybody to lay blame on, it aint me," he said mildly. "I said all along you ought to have had help. A man as is on his own ground, and knows his own ground, is more than a match for one cove, however hard he may work."

The detective turned fiercely upon his meek dependent.

"Who's blaming you?" he cried impatiently. "I wouldn't cry out before I was hurt, if I were you."

They had reached the railway station by this time.

"How long is it since you missed him?" asked Mr. Grimstone of the penitent Chivers.
