four o'clock
Walter was disposed to think the young man too suspicious . He was of a sanguine temperament , and he tried to persuade himself that there was really no good reason to suspect Mr. Locke of unfair dealing . He laid considerable stress upon the favorable reports of the agents who had called upon him during the day . At length four o'clock came , and he closed up the office , leaving the key with the janitor . He went home , not quite knowing whether he was to be congratulated or not . He decided not to say anything just yet about his engagement , lest it might turn out to be deceptive . Had he been quite sure that it was substantial and to be relied upon , he would have written to his guardian to announce the good news , but he thought it best to wait .
