"I wonder whether we shall ever see him again?" thought Harry, as he turned down one of the quiet streets, intending to make a circuit and return to the chambers by another route. His thoughts were busy now,-- he was running over in a half-troubled way the words of the sergeant that night, for they had left their impression; then he felt disheartened and sad, as he thought of Patty's intimacy with the Decadia people, and the way in which she was dragged into the affair, trembling, too, as it struck him that there might be legal inquiry, and she called upon to give evidence. At last he came to the conclusion that he would go and boldly beg of Jared Pellet to keep her away from the wretched district, and quickened his steps as if about to go at once, till he recollected the hour, and once more slackened his pace. The street was perfectly empty, the lines of lamps looking in the distance like a vista of golden beads hung in the air. Suddenly he was aroused from his musings, and, turning sharply, he was face to face with, and so close as to be even touching, his follower, who, with one arm upraised, was about to seize him by the neck, the gaslight falling full upon the features of Mr John Screwby. Mr John Screwby had indeed been about to administer the garotter's hug, for he had followed Harry through the frequented streets till he had turned into one that was retired, and afforded an opportunity that this gentleman did not feel disposed to resist. Times had been what he termed "hardish" lately. Buoyed up by the hope of obtaining the reward, he had fallen into the habit, while hope lasted, of boasting among his companions of the luck about to fall to his share. That luck, though, had never been his; and the failure of several little adventures had also tended to lower Mr Screwby's banking account. Hence, then, he had been on the look out for an unconsidered trifle or two. The opportunity was excellent--the hour was late. A glance up and down the street had shown him that there was not a soul in sight, while as to the houses, for the most part the lights were now in the upper stories. Mr John Screwby's teeth glistened brightly, and with rapid action he stepped forward, at the same time softly turning up his cuffs as if to strike. It was a chance and no mistake, he thought. Nothing could have happened better--cash, a watch and chain, and a bit of revenge, all at one swoop. For if it had not been for this swell, the old gentleman would have written his cheque for the reward, and it would have been cashed, and there would have been an end of it. A quarter--one half of the street had been traversed, and Screwby told himself that it was time to close. He gave another glance behind him-- all right. If he had only had a mate now, how easy the job would have been. But then a mate would have wanted half the proceeds, and there might have been a row afterwards, and a split, so that it was better so.
