six o'clock
`` I am Jane Pool . I am nurse to Sir Victor Catheron 's infant son . Early in August I entered the service of the deceased Lady Catheron in London ; the first week of September I accompanied them down here . On the evening of the murder , about half-past six o'clock , or perhaps a quarter of seven , while I was busy in the day nursery over my duties , my lady came in , as she often did , though not at that hour . She looked pale and flurried , and bent over baby , who lay asleep , without speaking . Sir Victor came in while she was still there , and without taking any notice of me , told her he had received a note from Lady Helena Powyss saying Squire Powyss had had a stroke , and that he must go at once to Powyss Place . He said he thought he would be absent all night , that he would return as soon as he could , and that she was to take care of herself .
