“I have not seen any dog near the house. Do they keep any?”

“No.”

“That is lucky. A determined dog is sometimes a troublesome customer. I recollect, one night, Dick Hargrave and I had planned a little expedition of this kind, when it was all broken up by a cursed bull-dog, who rushed out upon us as if he would tear us to pieces; and, to tell the truth, he did tear Dick’s coat off his back.”

Helen listened in dismay; for it revealed to her what she had not known,—that her uncle had been implicated in affairs of a similar kind before. It will be remembered that Armstrong, in proposing to her to co-operate with him, had used the pretext that Mr. Gregory had cheated him, and that he was resolved to repay himself. This, Helen had believed at the time; but his present unguarded remarks led her to entertain strong doubts of its truth. Her strong natural dislike for the duplicity and treachery required at her hands determined her, in spite of her habitual timidity and fear of her companion, to venture a remonstrance. This, however, she delayed till he should make a specific demand upon her.

He resumed: “I don’t know but there’s a pretty good chance of success. To-night is Tuesday night. I can’t very well get ready before Friday. On that night, you must contrive, in some manner,—taking care to incur no suspicion,—to come down stairs and unlock the front door. I shall be on hand at one o’clock. Be very particular about the time; for what I do must be done quickly.”

“But, uncle, wouldn’t that be robbery?”

“Robbery! Didn’t I tell you that old Gregory had cheated me out of more than the sum I shall take?”

“But they have treated me kindly; and it makes me feel ashamed to know that I am trying to injure them, uncle”——

“Don’t call me uncle again! I’m no uncle of yours,” said Armstrong, roughly. Noticing the child’s look of surprise, he added, “There, the murder is out! I had intended to treat you as a niece; but you don’t deserve it. It is time to talk to you in a different strain. I declare to you, Helen, that, unless you comply with my command, I will make you repent it most bitterly. Do you hear?”

“Yes,” said Helen, terrified no less by his looks than his words.
