In the library she had, a year ago, discovered a strange old book--one which sixty years before had been in universal circulation--entitled _Satan's Invisible World Discovered_, and she had read it from beginning to end.
This book had, perhaps, more influence upon the simple-minded country people in Scotland than any other work.

It consisted entirely of relations of ghosts of murdered persons, witches, warlocks, and fairies; and as it was read as an indoor amusement in the presence of children, and followed up by unfounded tales of the same description, the youngsters were afraid to turn round in case they might be grasped by the "Old One." So strong, indeed, became this impression that even grown-up people would not venture, through fear, into another room or down a stair after nightfall.
Her experience in the old castle had, to say the least, been remarkable.
Those weird whisperings were extraordinary.

For hours she lay reflecting upon the many traditions of the old place, some recorded in the historic notices of the House of the Montrose, and others which had gathered from local sources--the farmers of the neighbourhood, the keepers, and servants.

Those noises in the night were mysterious and puzzling.
Next morning she went alone to the kennels to find Stewart and to question him.

He had told her many weird stories and traditions of the old place, and it struck her that he might be able to furnish her with some information regarding her strange discovery.
