seven o'clock
He seemed absolutely unwearied and unimpaired ; never bored and never carried away . Eastman always smiled when he met Cavenaugh in the entrance hall , serenely going forth to or returning from gladiatorial combats with joy , or when he saw him rolling smoothly up to the door in his car in the morning after a restful night in one of the remarkable new roadhouses he was always finding . Eastman had seen a good many young men disappear on Cavenaugh 's route , and he admired this young man 's endurance . To-night , for the first time , he had got a whiff of something unwholesome about the fellow -- bad nerves , bad company , something on hand that he was ashamed of , a visitor old and vicious , who must have had a key to Cavenaugh 's apartment , for he was evidently there when Cavenaugh returned at seven o'clock . Probably it was the same man Cavenaugh had seen in the hansom . He must have been able to let himself in , for Cavenaugh kept no man but his chauffeur ; or perhaps the janitor had been instructed to let him in . In either case , and whoever he was , it was clear enough that Cavenaugh was ashamed of him and was mixing up in questionable business of some kind .
