midnight precisely
He lived alone in his house in Saville Row , and no one called upon him , or at any rate entered there . One servant sufficed for him . He took all his meals at his club , but he never shared a table with any of his acquaintance , nor did he ever invite a stranger to dinner . He only returned home to sleep at midnight precisely , for he never occupied any one of the comfortable bedrooms provided by the `` Reform '' for its members . Ten hours of the four-and-twenty he passed at home , partly sleeping , partly dressing or undressing . If he walked , it was in the entrance-hall with its mosaic pavement , or in the circular gallery beneath the dome , which was supported by twenty Ionic columns . Here he would pace with measured step .
