About half a mile from the town, standing in an old park famous for its huge beech trees, is the ancient Manor House of Birlstone. Part of this venerable building dates back to the time of the first crusade, when Hugo de Capus built a fortalice in the centre of the estate, which had been granted to him by the Red King. This was destroyed by fire in 1543, and some of its smoke-blackened corner stones were used when, in Jacobean times, a brick country house rose upon the ruins of the feudal castle.
The Manor House, with its many gables and its small diamond-paned windows, was still much as the builder had left it in the early seventeenth century. Of the double moats which had guarded its more warlike predecessor, the outer had been allowed to dry up, and served the humble function of a kitchen garden. The inner one was still there, and lay forty feet in breadth, though now only a few feet in depth, round the whole house. A small stream fed it and continued beyond it, so that the sheet of water though turbid, was never ditchlike or unhealthy. The ground floor windows were within a foot of the surface of the water.
The only approach to the house was over a drawbridge, the chains and windlass of which had long been rusted and broken. The latest tenants of the Manor House had, however, with characteristic energy, set this right, and the drawbridge was not only capable of being raised, but actually was raised every evening and lowered every morning. By thus renewing the custom of the old feudal days the Manor House was converted into an island during the night — a fact which had a very direct bearing upon the mystery which was soon to engage the attention of all England.
The house had been untenanted for some years and was threatening to moulder into a picturesque decay when the Douglases took possession of it. This family consisted of only two individuals — John Douglas and his wife. Douglas was a remarkable man, both in character and in person. In age he may have been about fifty, with a strongjawed, rugged face, a grizzling moustache, peculiarly keen gray eyes, and a wiry, vigorous figure which had lost nothing of the strength and activity of youth. He was cheery and genial to all, but somewhat offhand in his manners, giving the impression that he had seen life in social strata on some far lower horizon than the county society of Sussex.
Yet, though looked at with some curiosity and reserve by his more cultivated neighbours, he soon acquired a great popularity among the villagers, subscribing handsomely to all local objects, and attending their smoking concerts and other functions, where, having a remarkably rich tenor voice, he was always ready to oblige with an excellent song. He appeared to have plenty of money, which was said to have been gained in the California gold fields, and it was clear from his own talk and that of his wife that he had spent a part of his life in America.
The good impression which had been produced by his generosity and by his democratic manners was increased by a reputation gained for utter indifference to danger. Though a wretched rider, he turned out at every meet, and took the most amazing falls in his determination to hold his own with the best. When the vicarage caught fire he distinguished himself also by the fearlessness with which he reentered the building to save property, after the local fire brigade had given it up as impossible. Thus it came about that John Douglas of the Manor House had within five years won himself quite a reputation in Birlstone.
His wife, too, was popular with those who had made her acquaintance; though, after the English fashion, the callers upon a stranger who settled in the county without introductions were few and far between. This mattered the less to her, as she was retiring by disposition, and very much absorbed, to all appearance, in her husband and her domestic duties. It was known that she was an English lady who had met Mr. Douglas in London, he being at that time a widower. She was a beautiful woman, tall, dark, and slender, some twenty years younger than her husband, a disparity which seemed in no wise to mar the contentment of their family life.
