"By operating on the mind—by modelling the imagination of that young girl to suit my purpose," answered Sir Henry. "With a woman of the world like you, this is an easy task. Insinuate certain notions into her bosom—inflame her—excite her——"

"This is more difficult than you imagine," interrupted Mrs. Slingsby: "because she and her sister are constantly together."

"Devise a means to employ Adelais in one room for two or three hours at a time, while you have Rosamond with you in another," said Sir Henry. "If you enter on the task with a good will, you will find it easy enough."

"But in ten days Adelais will become the wife of Clarence; and the sisters, accompanied by him, will repair to Torrens Cottage to throw themselves at the feet of the incensed father. Rosamond will then quit my house altogether."

"Ten days are sufficient to imbue her now innocent mind with such new sensations—such voluptuous thoughts—such eager desires, that her surrender will be easy and certain," persisted the atrocious villain, who thus calmly reasoned on the means of undermining so much virtue.

"I do not think so," observed Mrs. Slingsby. "If I proceed too rapidly, I shall alarm her, instead of inflaming her imagination. Besides, you judge the world by what you yourself are, and by what you know of me. But, frail and guilty as I am, Henry," she added in an impressive tone, "believe me when I declare my conviction that more virtue is to be found in woman than you would be inclined to suspect."

Sir Henry laughed heartily at this observation; then, rising from his seat, he took up his hat, saying, "At all events, dearest Martha, act so that I may present you with the cheque as soon as possible."

He kissed her, and departed from the house, chuckling at the success of his endeavour to make his mistress the instrument of his diabolical design against the pure—the beautiful—the unsuspecting Rosamond.

CHAPTER XXXVII.
TOM RAIN AND JACOB.

It was Saturday evening; and Rainford was proceeding up Gray's Inn Lane, wrapped in his white great coat, and with a woollen "comforter" reaching up almost to his nose, when he suddenly felt some one pull him by the sleeve.
