two o'clock
The Nurse came with him to the door of the sick-room , taking her last instructions . Miss Trelawny sat still beside the bed . Sergeant Daw , who had entered as the Doctor went out , was some little distance off . When Nurse Kennedy joined us , we arranged that she should sit up till two o'clock , when Miss Trelawny would relieve her . Thus , in accordance with Mr. Trelawny 's instructions , there would always be a man and a woman in the room ; and each one of us would overlap , so that at no time would a new set of watchers come on duty without some one to tell of what -- if anything -- had occurred . I lay down on a sofa in my own room , having arranged that one of the servants should call me a little before twelve . In a few moments I was asleep .
