in the early days of Elizabeth by the first Earl of Stanchester, her celebrated minister, it was in the form of a quadrangle with wings abutting from the sides and ending at the extremities in towers, while its princely proportions were such as to place it among the largest and most notable family mansions in the country. The last rays of sunset flashed upon its many windows as I emerged from the avenue, and then passing across the level lawns and ancient bowling-green, I entered the great hall with its wonderful ornamental fireplace and stands of armour, and proceeded along one corridor after another to the cosy room in the west wing which served me as study. From the window where I stood for a moment in deep reflection I commanded a view for several miles across the great level park which was some ten miles in extent, and where, in the distance, rose another low, old-fashioned Jacobean building with clock-tower, the kennels of the Earl’s famous foxhounds.

The room had been given to me so that I should not be disturbed by visitors who, owing to the enormous proportions of the place, usually wandered about hopelessly lost in their attempt to reach their rooms without a servant as guide. The name of Keene was puzzling me. Somehow I had a distinct and vivid recollection of having heard it before, but in what connexion I could not recollect, although I had been racking my
