one o’clock
`` When the invisible guests appeared to have had all they could eat , she began the chatty part again , and never seemed to be disturbed but once , when she requested some one not to sing so loud for fear of disturbing the family . `` Altogether it was the weirdest and rummest thing I 'd ever seen in my life . We watched it for one full hour , and then we quit because she did . At one o'clock she apparently bade her guests good-night , after which she gathered up and put away all the eatables there were left -- and , of course , everything but what she had eaten herself still remained -- cleaned all the dishes , restored them to their proper places in the dining-room pantry , and went back up-stairs to her room . `` Mr. Perkins and I did n't know what to make of it . There was n't a thing stolen , and it was clear to my mind that I 'd done the woman an injustice in connecting her with thieves . She was honest , except in so far as she had ordered all those salads and creams and things from time to time on Mr. Perkins 's account , which was easy enough for her to do , since Mrs. Perkins let her do the ordering .
