He went in the middle of the morning, when there was the greatest amount of sane, wholesome activity around the ancient, crumbling shops and warehouses. The museum's sign was still there, and as he approached he saw that the place was still open. The gateman nodded in pleasant recognition as he summoned up the courage to enter, and in the vaulted chamber below an attendant touched his cap cheerfully. Perhaps everything had been a dream. Would he dare to knock at the door of the workroom and look for Rogers?
