Clement did not let the grass grow under his feet. An hour later he was rattling over the stony pavements and through the crowded streets of the busy town, which had grown in a short hundred years from something little more than a village, to be the second centre of wealth and population, of poverty and crime, within the seas; a centre on which the eye of Government rested with unwinking vigilance, for without a voice in Parliament and with half of its citizens deprived of civic rights--since half were Nonconformists--it was the focus of all the discontent in the country. In Manchester, if anywhere, flourished the agitation against the Test Acts and the movement for Reform. Thence had started the famous Blanketeers, there six years before had taken place the Peterloo massacre. Thence as by the million filaments of some great web was roused or calmed the vast industrial world of Lancashire. The thunder of the power-loom that had created it, the roar of the laden drays that shook it, deafened the wondering stranger, but more formidable and momentous than either, had he known it, was the half-heard murmur of an underworld striving to be free.

Clement had never visited the cotton-town before, and on a more commonplace errand he might have allowed himself to be daunted by a turmoil and bustle as new to him as it was uncongenial. But with his mind set on one thing, he heeded his surroundings only as they threatened to balk his aim, and he had himself driven directly to the Police Office, over which the notorious Nadin had so lately presided that for most people it still went by his name. Fearless, resolute, and not too scrupulous, the man had through twenty troublous years combated the forces alike of disorder and of liberty; and before London had yet acquired an efficient police, he had gathered round him a body of men equal at least to the Bow Street Runners. He had passed, but his methods survived; and half an hour after Clement had entered the office he issued from it accompanied by a hard-bitten, sharp-eyed man in a tall beaver hat and a long wide-skirted coat.

"The Apple Tree? Oh, the Apple Tree's on the square," he informed Clement. "And Jerry Stott? No harm in him, sir, either. He'll speak when he sees me."

"You don't think we need another man?"

"There's one following. No use to go in a bunch. He'll watch the front, and we'll go in by the yard. Got a barker, sir?"

"Yes."

"'Fraid so. Well, don't use it--show it if you like. Law's law, and a live dog's worth more than its hide. Ay, that's Chetham's. Queer old place, and--sharp's the word, here we are," as they turned off Long Mill Gate, and entered the yard of an old-fashioned house, over the door of which hung the sign of an apple-tree. The place was quiet, in comparison with the street they had left, and "Here's Jerry," the officer added, as they espied a young fellow, who in a corner of the enclosure was striving to raise to his shoulder a truss of hay. He ceased his efforts when he saw them.

"We want a word with you," said the officer.

The man eyed them with dismay. "I never thout 'at he'd come to thee," he said.

"The chap you brought in this morning?"

"Ay, sure."

"Happen yes and happen no," the policeman replied. "What's it all about?"

"If he says I took his eauts he be a leear. I wurna wi' the sack, not to say alone 'at is, not five minutes, and yo' may look at t' sack and see all's theer as ever was! Never a handfu' missing, tho' the chap he cursed and swore an' took on, the mout ha' been eauts o' gowd! He's a leear iv he says I tetched 'em, but I never thout he'd t' brass to come to thee."

"Why not, lad?"

"'Cause i' the end he let up and steared at t' sack leek a steck pig, and then he fell a shriking 'i worse shap than ever, and away he goes as iv a dog had bit him and down t' Long Gate hell for leather!"

"Which way? I see. Did he take the oats?"

"Not he, nor t' bag. An after mekking setch a din about his eauts! I war no wi' 'em five minutes."

The officer declined to commit himself. "Let us see them," he said.

Jerry led them to a tumble-down, black and white building at the rear of the yard, with lattice work in its crazy windows and an old date over the door. They followed him up a ladder and into a loft, where were a frowsy bed or two, some old pack-saddles, and two or three stools made out of casks sawn in two. On the floor in one place lay a heap of oats trampled this way and that, and beside the heap an empty sack. The officer picked up the sack, shook it and examined it.

"What do you make of it?" Clement asked.

"I don't know what to make of it. Here, you, Jerry, fetch me a corn measure!" And when he had thus rid them of the lad, "He may be carrying out orders and telling a flash tale to put us off. Or he may be telling the truth, and in that case it looks as if someone had been a mite brighter than your man and cleared his stuff."

"But where is it?"

"Ah! Just so, I'd like to know," shaking his head. "Yes, Jerry, measure it back into the sack. How much is there?"

The lad began to gather up the oats and replace them in the bag, while the two men looked on, perplexed and undecided. Suddenly Clement stooped--a scrap of cord, doubtless the cord which had tied the neck of the sack, had caught his eye. He picked it up, looked at it, then, with a word, he handed it to the officer. "I think that settles it," he said, his eyes shining. There was a tiny twist of straw-plait, like a rosette, knotted about the cord and still adhering to it.

Nadin's man looked at the plait and for a moment did not understand. Then his face cleared. "By Joseph! You're right, sir!" he exclaimed, and slapped his thigh. "And sharp, sharp too. You'd ought to be one of us! That settles it, it's the backtrack we've to look to, but I'll take no chances." And turning to the lad and addressing him in his harshest voice, "See here, in an hour we shall know if you've told us the truth. If you've not it will be the New Bailey and a pair of iron garters for you. So if you've aught to add, out with it! It's your last chance, Jerry Stott."

But the lad protested that he'd told all the truth. It had happened just as he had told them.

The officer turned to Clement. "I think he's on the square," he said, "but I'll have him watched." And he led the way down the ladder. When they reached the street, he stepped out smartly, making nothing of the crowd and bustle, the lumbering drays and over-hanging cranes through which they had to thread their way. "We'll catch the Altringham stage at the Cross if we're sharp," he said. "It'll be quicker than getting out a po'chay and a lot cheaper."

They caught the stage, and alighted in Altringham before five. A walk of as many minutes brought them to the Barley Sheaf, a wagoner's house at the corner of a lane in the poorest part of the town. The ostler, from whom Clement had so lately parted, stood leaning against a post at the entrance to the yard, his hands still in his pockets and the straw still in his mouth. When he saw them a grin broke up his ugly face. "He've been here," he cried, "but," triumphantly, "I've routed him, mister! I sent him all ways!"

The officer did not respond. "Why, the devil, didn't you seize him?" he growled.

"What, me? And him double my size? And a desperate villain? 'Deed, I'd to save my skin, mister, and only yon lad and a couple of childer in the yard when he come. I see him first, sneaking a look round this yere post, and thinks I, it'll be a knife in the back or a punch in the face for me if he's heard I've rapped. So, first's better than last, thinks I, and seeing as he hung back I up to him bold as brass, but with one eye on the lad too, and sez I, 'Can you read?' sez I. He looked at me's if he'd have my blood, but there was the lad and the childer a-staring, so 'Ay, I can,' says he, 'and can read you, you thieving villain!' 'Well, if you can read, read that,' sez I, and pointed to a bill as was posted on the gate. 'I can't,' sez he, 'and, happen you can tell me what 'tis all about.' He looks, and he sees 'tis the bill about he, and painting him to the life. Anyways, he turns the color o' whey and he gives me a look as if he'd cut out my inwards, but he sees it's no good, for there was the lad and the childer, and he slinks off. Ay, I routed him, I did, little as I be, mister!"

"Right!" said Nadin's man. "And now do you show us the sack as you changed for his."

The man's face fell amazingly, but Clement noted that he looked surprised rather than frightened. "Eh?" he exclaimed. "Lord, now, who told you, mister? He didn't know."

"Never mind who told us. We know, and that's enough. There was a twist o' plait round the cord?"

"There were."

"You said nothing about it before. But out with it now, and do you take care, my lad."

"Well, who axed me? Exchange is no robbery and I ain't afeard. 'Twas just this way. He sold me three sacks, 's I told you, squire, and I was hauling 'em off to stable when 'Not that one!' says he sharp. So then I look at t' one he was so set on keeping, and when his back was turned I hefted it sly-like, and it seemed to me a good bit heavier than t' others. Then I spied the bit o' plait about the cord, and thinks I, being no fule, 'tis a mark. And when he went in for a squib o' cordial wi' Jerry Stott I shifted t' mark to another sack and loaded up, and off he goes and he none the wiser, and no harm done. Exchange is no robbery and you can't do nowt to me for that."

"I don't know," said the officer darkly. "Let us see the sack."

"You're not agoing----"

"Do you hear? Jump, unless you want to get into trouble. You show us that sack, and be quick about it, my lad."

Grumbling, but not daring to refuse, the old man led the way into the stables, and there in an empty stall the three sacks stood upright. "Which is the one you filched?" asked the man from Manchester.

Reluctantly the ostler pointed it out. "Then you get me a horse-cloth."

"You're not going--well, a wilful man must have his way. Will that serve you? But if my oats is spilled and spiled----"

Nadin's man paid no heed to his remonstrance, but in a trice cut the cord that tied the ............
