"You are right, Isadore," replied Mrs. Falkland: "the fact may be of no importance, but it may be of much; and, consequently, it is worth our own examination. I will go with you, my love, if Marian be still asleep. Wait one moment, and we will go and judge together." Mrs. Falkland was not long absent. Marian was still lying overpowered with the opium; and the two ladies, having joined the boy in the hall, set out upon the search. While her mother was absent, however, Isadore called her own maid, and stationed her at one of the windows, whence she could see the spot to which the boy referred, and the path leading to it. She gave her also directions to remain there, and, in case of either Mrs. Falkland or herself making a signal, to send or come down to them in all haste. "I feel a sort of presentiment," thought Isadore, as she gave the orders, "that this expedition will end in something of importance." Whatever it was likely to end in, the maid obeyed her orders as punctually as such orders generally are obeyed; that is to say, she remained two minutes at the window; and having seen Mrs. Falkland and Isadore walk about a hundred steps upon the path, she thought, "Dear me! I can just get the cap I was trimming, and be back again here long before they are at the other side of the park." But, as she crossed the hall, she met with the old butler, who detained her just to ask her where his mistress and Miss Falkland were gone; and then told her a story, which he had heard when he was young, and the incidents of which were very like those connected with the fate of poor Mr. Edward de Vaux. Every hair on the maid's head stood on end, and gave her so much occupation, that, ere she could get back to her post, it was too dark to trim the cap any further; she therefore, immediately and punctually, turned her eyes on the spot which her mistress had directed her to observe, and watched most carefully, now that she could see nothing at that distance.
