midnight
When the family moved into this mansion , it was with a consciousness that the only one who really belonged there was Celia . She alone could behave like one perfectly at home . It seemed entirely natural to the others that she should do just what she liked , shut them off from her portion of the house , take her meals there if she felt disposed , and keep such hours as pleased her instant whim . If she awakened them at midnight by her piano , or deferred her breakfast to the late afternoon , they felt that it must be all right , since Celia did it . She had one room furnished with only divans and huge , soft cushions , its walls covered with large copies of statuary not too strictly clothed , which she would suffer no one , not even the servants , to enter . Michael fancied sometimes , when he passed the draped entrance to this sacred chamber , that the portiere smelt of tobacco , but he would not have spoken of it , even had he been sure . Old Jeremiah , whose established habit it was to audit minutely the expenses of his household , covered over round sums to Celia 's separate banking account , upon the mere playful hint of her holding her check-book up , without a dream of questioning her .
