eleven o'clock
Thus concealed from the eyes of any chance watcher , he contrived to approach one end of the terraced slope which formed the garden front of the castle . Each terrace was adorned with stone balustrades , surmounted by large vases , also of stone ; and , sheltered by these vases , Milsom ascended to the southern angle of the great pile of building . Seven lighted windows at this southern end of the castle indicated the apartments occupied by the heiress of Raynham and her eccentric guardian . The lights burned but dimly , like the night-lamps left burning during the hours of rest ; and Milsom had ascertained from Mr. Harwood that the household retired before eleven o'clock , at the latest . The apartments occupied by the little girl were on the first floor . The massive stone walls here were unadorned with ivy , nor were there any of those elaborate decorations in stonework which might have afforded a hold for the foot of the climber . The bare stone wall frowned down upon Thomas Milsom , impregnable as the walls of Newgate itself .
