“As Sandy and his wife warmed to the tale, one tripping up another in their eagerness to tell everything, it gradually developed as distinct a superstition as I ever heard, and not without poetry and pathos. How long it was since the voice had been heard first, nobody could tell with certainty. Jarvis's opinion was that his father, who had been coachman at Brentwood before him, had never heard anything about it, and that the whole thing had arisen within the last ten years, since the complete dismantling of the old house: which was a wonderfully modern date for a tale so well authenticated.

During these months, the darkest of the year, scarcely a night passed without the recurrence of these inexplicable cries.
