In daily, normal existence the mind is merely a whirlpool, but undoubtedly the criminal would concentrate mentally on every detail of her crime. There would be a focalization of her mind; a concentration of her whole mental faculties upon this one single subject, and when the mental force is reduced from its normal, dissipated condition into coherency, its power is unlimited. It is possible to catch a physical disease by sleeping in an infected bed. It is quite as easy to catch a mental disease by the same means. Many emotions are highly contagious, notably fear. All are invisible to human sight, and there is rarely any warning. A Psychic may sense something unpleasant before infection is established. In fact, this often happens to quite normal individuals. Something in the atmosphere of a place conveys a warning, is unpleasant or uncongenial and it is avoided. If a warning was conveyed to me in the Highland inn I was too tired to heed it. At one time in my life I saw a great deal of two intimate and charming friends, Lord and Lady Wynford. Alas! both have now passed over. Lady Wynford was born Caroline Baillie of Dochfour, and owing to her Scotch blood, and her relationship with many of our great Scotch families, she was profoundly interested in ghosts. Lord Wynford, on the contrary, had an absolute horror of the subject, and always left the room whilst it was under discussion. Though very dissimilar, husband and wife were the best of friends. She was very handsome and a brilliant woman of the world. He was shy, retiring, and deeply religious. A perfect example of a true gentleman of the old school, and an aristocrat to his finger-tips. I was devoted to them both, and they were very kind to me in giving me their warm friendship, though at the time of which I write I was only a girl of about twenty years old. At that period the great topic of conversation amongst ghost-hunters was Glamis Castle, the most celebrated of all haunted houses. No ghost book is ever considered complete without reference to this celebrated Castle, and the story usually narrated is, that in the secret room some abnormal horror lived, and that the heir, Lord Glamis, and the factor, had to be told of its existence by the Earl of Strathmore in person. This information was of so terrible a nature that it changed not only the lives of those two men, but even their personal appearance. They grew aged and haggard in a single night. This story was readily discussed in old days by members of the Strathmore family, who were just as keen as outsiders were to probe the mystery. To-day it is universally believed that the monstrosity is at last laid to rest, and that though other ghosts still walk the Castle, the worst has departed forever.
