"But, how was it that you let the villain escape, Master Cyril? Why did you not run him through the body?"

"I had other things to think of, John. There was Mrs. Harvey lying insensible, and the servant desperately wounded, and I thought more of these than of the robber, and was glad enough, when he ran out, to be able to turn my attention to them."

"Ay, ay, that was natural enough, lad; but 'tis a pity the villain got off scot-free. Truly it is not safe for two old people to be in an empty house by themselves in these times, specially as, maybe, the houses on either side are also untenanted, and robbers can get into them and make their way along the roof, and so enter any house they like by the windows there. It was a mercy you chanced to come along. Men are so accustomed now to hear screams and calls for aid, that none trouble themselves as to such sounds. And you still feel quite well?"

"Never better, John, except for occasional twitches in my shoulder."

"It does not knit so fast as it should do," John said. "In the first place, you are always on the move; then no one can go about into infected houses without his spirits being disturbed, and of all things a calm and easy disposition is essential for the proper healing of wounds. Lastly, it is certain that when there is poison in the air wounds do not heal so quickly as at other times."

"It is going on well enough, John; indeed, I could not desire it to do better. As soon as it is fairly healed I ought to join Prince Rupert again; but in truth I do not wish to go, for I would fain see this terrible Plague come to an end before I leave; for never since the days of the Black Death, hundreds of years ago, was there so strange and terrible a malady in this country."

Mr. Wallace had returned to his house when Cyril called the next morning.

"Thinking over what you said last night, Cyril, I arrived at a pretty correct conclusion as to what had happened, though I thought not that it could be as bad as it was. I knew the object with which Mr. Harvey and his wife had come up to London, at a time when most men were fleeing from it. Their son has, ever since he came up three years ago, been a source of grievous trouble to them, as he was, indeed, for a long time previously. Some natures seem naturally to turn to evil, and this boy's was one of them. It may be that the life at home was too rigid and severe, and that he revolted against it. Certain it is that he took to evil courses and consorted with bad companions. Severity was unavailing. He would break out of the house at night and be away for days. He was drunken and dissolute.

"At last, just after a considerable sum of money had come into the house from the tenants' rents, he stole it, and went up to London. His name was not mentioned at home, though his father learnt from correspondents here that he had become a hanger-on of the Court, where, his father being a man of condition, he found friends without difficulty. He was a gambler and a brawler, and bore a bad reputation even among the riff-raff of the Court. His father learnt that he had disappeared from sight at the time the Court went to Oxford early in June, and his correspondent found that he was reported to have joined a band of abandoned ruffians, whose least crimes were those of robbery.

"When the Plague spread rapidly, Mr. Harvey and his wife determined to come up to London, to make one more effort to draw him from his evil courses. The only thing that they have been able to learn for certain was, that he was one of the performers in that wicked mockery the dance of death, but their efforts to trace him have otherwise failed.
