Mr. Caerlyon tapped at her door, and called out that there was a letter for her, and the waiting woman brought it to Margaret, who received it eagerly, hoping that it was from Dr. Gay, after all.

But she perceived in a moment that it was not, and saw, with disgust, the large, sprawling characters on the back of the note, and the dirty wafer which closed it, in lieu of an envelope.

With shrinking fingers she opened it, and read these words:

"Ma'am:—You knows doosed well who's a talkin' te yer by this here. If you be's the brick I takes yer for, yer won't be sulky, and throw away yer only chance, for mean spite. Come, now, jest give me yer note of hand that yer'll return that 'ere stole pocket-book to its owner whenever yer sees Regis agin, and yer'll see more of yer admirin' friend; but act ugly, and wake the devil in the col., and—ware-hawk! yer'll be awhile on the road back—that's all.

"Yours to command,

"Pocket Pistol."

"No, you wretch," said Margaret, "I shall not give up the pocket-book which condemns Mortlake. I simply defy your threats, and shall be well guarded in future. My doubts are answered. I know what Mortlake's new order was; there it is," she cried, tossing the villainous-looking scrawl upon the table, "and I defy it! He offers me my life in exchange for my proofs, and I scorn his offer, I would rather bring such a fiend to justice than live a happy life, knowing that I had suffered him to elude his just punishment."

She called Mr. Caerlyon in.

"Who brought that letter?" asked she.

"A ferry rakket poy, matam," returned he.

"Is he waiting for an answer?"

"Yes, inteet, matam, ant playing with a crown-piece he says the gentleman gave him to holt his tongue."
