about four o'clock in the
afternoon
Frank was relieved by a young man who told him to go and get breakfast , and then to go to bed . `` You 'll have day work after to-night , '' he said , and Frank was glad to hear it . The darkness was made worse by the sudden alarms from the patients ' rooms . Frank slept late that day , and went on duty about four o'clock in the afternoon . That night passed quietly , but he did not dare knock on the door of room twenty-eight . He was afraid the man might be suffering from one of his insane attacks . The boy had almost lost heart but he had not altogether given up .
