At Thornwick, Tom had been descried in the yard, by the spying organs of one of the servants--a woman not very young, and not altogether innocent of nightly interviews. Through the small window of her closet she had seen, and having seen she watched--not without hope she might be herself the object of the male presence, which she recognized as that of Tom Helmer, whom almost everybody knew. In a few minutes, however, Letty appeared behind him, and therewith a throb of evil joy shot through her bosom: what a chance! what a good joke! what a thing for her to find out Miss Letty; to surprise her naughty secret! to have her in her power! She would have no choice but tell her everything--and then what privileges would be hers! and what larks they two would have together, helping each other! She had not a thought of betraying her: there would be no fun in that! not the less would she encourage a little the fear that she might, for it would be as a charm in her bosom to work her will withal!--To make sure of Letty and her secret, partly also in pure delight of mischief, and enjoyment of the power to tease, she stole down stairs, and locked the kitchen door--the bolt of which, for reasons of her own, she kept well oiled; then sat down in an old rocking-chair, and waited--I can not say watched, for she fell fast asleep. Letty lifted the latch almost too softly for her to have heard had she been awake; but on the door-step Letty, had she been capable of listening, might have heard her snoring. When the young woman awoke in the cold gray of the morning, and came to herself, compunction seized her. Opening the door softly, she went out and searched everywhere; then, having discovered no trace of Letty, left the door unlocked, and went to bed, hoping she might yet find her way into the house before Mrs. Wardour was down.
