About three o’clock
`` Thank you ; thank you , '' I answered . `` That will be much better . When shall I come ? '' `` About three o'clock . '' I went wandering about the woods , and at three I was again in the housekeeper 's room . She came to me presently , looking rather troubled . `` It is very odd , '' she began , the moment she entered , `` but for the first time , I think , for years , she 's not for her afternoon sleep .
