It was a singular spot, and one peculiarly well suited to the grim humour of my patient. From the windows of our little whitewashed house, which stood high upon a grassy headland, we looked down upon the whole sinister semicircle of Mounts Bay, that old death trap of sailing vessels, with its fringe of black cliffs and surge-swept reefs on which innumerable seamen have met their end. With a northerly breeze it lies placid and sheltered, inviting the storm-tossed craft to tack into it for rest and protection. Then come the sudden swirl round of the wind, the blistering gale from the south-west, the dragging anchor, the lee shore, and the last battle in the creaming breakers. The wise mariner stands far out from that evil place. On the land side our surroundings were as sombre as on the sea. It was a country of rolling moors, lonely and dun-colored, with an occasional church tower to mark the site of some old-world village. In every direction upon these moors there were traces of some vanished race which had passed utterly away, and left as its sole record strange monuments of stone, irregular mounds which contained the burned ashes of the dead, and curious earthworks which hinted at prehistoric strife. The glamour and mystery of the place, with its sinister atmosphere of forgotten nations, appealed to the imagination of my friend, and he spent much of his time in long walks and solitary meditations upon the moor. The ancient Cornish language had also arrested his attention, and he had, I remember, conceived the idea that it was akin to the Chaldean, and had been largely derived from the Phoenician traders in tin. He had received a consignment of books upon philology and was settling down to develop this thesis when suddenly, to my sorrow and to his unfeigned delight, we found ourselves, even in that land of dreams, plunged into a problem at our very doors which was more intense, more engrossing, and infinitely more mysterious than any of those which had driven us from London. Our simple life and peaceful, healthy routine were violently interrupted, and we were precipitated into the midst of a series of events which caused the utmost excitement not only in Cornwall but throughout the whole west of England. Many of my readers may retain some recollection of what was called at the time "The Cornish Horror," though a most imperfect account of the matter reached the London press. Now, after thirteen years, I will give the true details of this inconceivable affair to the public.
