twelve o'clock
The next to appear was Sergeant Daw , who went quietly into the room and took the seat vacated by the Doctor . I still remained outside ; but every few minutes looked into the room . This was rather a form than a matter of utility , for the room was so dark that coming even from the dimly-lighted corridor it was hard to distinguish anything . A little before twelve o'clock Miss Trelawny came from her room . Before coming to her father 's she went into that occupied by Nurse Kennedy . After a couple of minutes she came out , looking , I thought , a trifle more cheerful . She had her respirator in her hand , but before putting it on , asked me if anything special had occurred since she had gone to lie down .
