Love is not always selfish; and goodness is sometimes its own reward. In that bitter hour of his first real misery, Bog did not regret his kindness to the Minfords, or take credit to himself for having nobly concealed from their knowledge those little weekly gifts of money which he sent to them through the mail, when they were in poorer circumstances. He was not for a moment base enough to think that Pet would look with kinder eyes on him, if she but knew of his secret benefactions--which, up to this time, neither she nor her father had suspected, and which they would never learn from his lips.


BOOK SIXTH.

MYSTERIES OF THE NIGHT.


CHAPTER I.

THE UNKNOWN HAND.

Marcus Wilkeson made no effort to discover the writer of the anonymous letter, because he knew that such an effort would be in vain. He called on Mr. Minford once in two or three days now. The inventor always took occasion to refer to the letter, and assured Marcus that it was not worth remembering, or talking about. "Why, then, did he talk about it?" Marcus asked himself. His eyes were not blind to watchful and suspicious glances which the old man directed to him, at times, under cover of those shaggy, overhanging eyebrows. Nor could he help noticing a strange reserve in the bearing of Pet toward him. It was not mere modesty, or timid gratitude, but DOUBT, as he read the signs. Marcus was convinced that the father had put his child on guard against something, though he might not have mentioned the existence of the anonymous letter. This thought distressed him acutely.

But his troubles, as well as his joys, he kept to himself. The miser puts his broken bank notes and his good gold under the same lock and key.

One evening, early in April, Overtop and Maltboy observed a peculiar expression of sadness on the face of their friend. He had eaten nothing at dinner, but had drunk more than his usual allowance of sherry. He had kept his eyes fixed on the table as in a revery, and had scarcely spoken a word. Miss Wilkeson, in her solemn state opposite the boiled chickens, was hardly less social.
