nine o'clock
Nurse Kennedy , who had been on duty all day , was lying down , as she had arranged to come on again by twelve o'clock . Doctor Winchester , who was dining in the house , remained in the room until dinner was announced ; and went back at once when it was over . During dinner Mrs. Grant remained in the room , and with her Sergeant Daw , who wished to complete a minute examination which he had undertaken of everything in the room and near it . At nine o'clock Miss Trelawny and I went in to relieve the Doctor . She had lain down for a few hours in the afternoon so as to be refreshed for her work at night . She told me that she had determined that for this night at least she would sit up and watch . I did not try to dissuade her , for I knew that her mind was made up .
