four o'clock
Once amid the prayers and litanies he was reciting with the Sisters , he lifted his head and found that she was looking at him and not at Augustina . Her expression was so forlorn and difficult to read , that he felt a vague uneasiness . But his Catholic sense of the deep awe of what he was doing made him try to concentrate himself upon it , and when he raised his eyes again Laura was gone . At four o'clock , in the dawn , he went himself to rest awhile , a little surprised , perhaps , that Laura had not come back to share the vigils of the night , but thankful , nevertheless , that she had been prudent enough to spare herself . Some little time before he went , while it was yet dark , Sister Rosa had gone to lie down for a while . Her room was just beyond Laura 's . As she passed Miss Fountain 's door she saw that there was a light within , and for some time after the tired nurse had thrown herself on her bed , she was disturbed by sounds from the next room .
