The Mikado Jewel by Fergus Hume — Read

The odd conversation with the Squire and Theodore Dane strangely affected Patricia, and in rather an unhealthy way. She was an ordinary commonsense Irish girl, whose father had been a matter-of-fact military man, and in her conventional life there had been no place for the supernatural. And when, with Colonel Carrol's death, came his daughter's subsequent poverty, Patricia had been far too much taken up with battling for existence to think of the Unseen. To be over-inquisitive about the next world seemed to her sensible mind unnecessary, since there was so much to be done on earth. She knew very well that she was sensitive to things which other people did not perceive, but she put this down to having highly-strung nerves, and thought very little about the matter. Now, apparently, the time had come for her to consciously use organs hitherto unguessed at.

Patricia could scarcely help feeling that the atmosphere of Beckleigh Hall was unusual. The isolation, the dreamy nature of Mara, the uncanny conversation of Theodore, which his uncle appeared to accept as quite ordinary -- all these things had an effect on her mind. She began to be vaguely afraid of the darkness, and her sleep was greatly disturbed by vivid dreams. In vain she assured herself that all this was owing to her imagination, and that she was losing her nerve in a most ridiculous manner, for the spell of the place was laid upon her, and she felt that she was being caught in those nets of the Unseen of which Mr. Colpster had spoken. To a healthy-minded girl, such as Miss Carrol undoubtedly was, the feeling was highly unpleasant, and she resented the influence which seemed bent upon controlling her, even against her will. Yet to this influence which she vaguely felt, but could not describe, she could not even put a name.
