Riderhood nodded, and the figure of the bargeman went its way along the soft turf by the side of the towing-path, keeping near the hedge and moving quickly. They had turned a point from which a long stretch of river was visible. A stranger to the scene might have been certain that here and there along the line of hedge a figure stood, watching the bargeman, and waiting for him to come up. So he himself had often believed at first, until his eyes became used to the posts, bearing the dagger that slew Wat Tyler, in the City of London shield.
Within Mr Riderhood’s knowledge all daggers were as one. Even to Bradley Headstone, who could have told to the letter without book all about Wat Tyler, Lord Mayor Walworth, and the King, that it is dutiful for youth to know, there was but one subject living in the world for every sharp destructive instrument that summer evening. So, Riderhood looking after him as he went, and he with his furtive hand laid upon the dagger as he passed it, and his eyes upon the boat, were much upon a par.
The boat went on, under the arching trees, and over their tranquil shadows in the water. The bargeman skulking on the opposite bank of the stream, went on after it. Sparkles of light showed Riderhood when and where the rower dipped his blades, until, even as he stood idly watching, the sun went down and the landscape was dyed red. And then the red had the appearance of fading out of it and mounting up to Heaven, as we say that blood, guiltily shed, does.
Turning back towards his Lock (he had not gone out of view of it), the Rogue pondered as deeply as it was within the contracted power of such a fellow to do. ‘Why did he copy my clothes? He could have looked like what he wanted to look like, without that.’ This was the subject-matter in his thoughts; in which, too, there came lumbering up, by times, like any half floating and half sinking rubbish in the river, the question, Was it done by accident? The setting of a trap for finding out whether it was accidentally done, soon superseded, as a practical piece of cunning, the abstruser inquiry why otherwise it was done. And he devised a means.
Rogue Riderhood went into his Lock-house, and brought forth, into the now sober grey light, his chest of clothes. Sitting on the grass beside it, he turned out, one by one, the articles it contained, until he came to a conspicuous bright red neckerchief stained black here and there by wear. It arrested his attention, and he sat pausing over it, until he took off the rusty colourless wisp that he wore round his throat, and substituted the red neckerchief, leaving the long ends flowing. ‘Now,’ said the Rogue, ‘if arter he sees me in this neckhankecher, I see him in a sim’lar neckhankecher, it won’t be accident!’ Elated by his device, he carried his chest in again and went to supper.
‘Lock ho! Lock!’ It was a light night, and a barge coming down summoned him out of a long doze. In due course he had let the barge through and was alone again, looking to the closing of his gates, when Bradley Headstone appeared before him, standing on the brink of the Lock.
‘Halloa!’ said Riderhood. ‘Back a’ ready, T’otherest?’
‘He has put up for the night, at an Angler’s Inn,’ was the fatigued and hoarse reply. ‘He goes on, up the river, at six in the morning. I have come back for a couple of hours’ rest.’
‘You want ’em,’ said Riderhood, making towards the schoolmaster by his plank bridge.
‘I don’t want them,’ returned Bradley, irritably, ‘because I would rather not have them, but would much prefer to follow him all night. However, if he won’t lead, I can’t follow. I have been waiting about, until I could discover, for a certainty, at what time he starts; if I couldn’t have made sure of it, I should have stayed there.—This would be a bad pit for a man to be flung into with his hands tied. These slippery smooth walls would give him no chance. And I suppose those gates would suck him down?’
