A man came into view on the drive at the side of the house: a servant to care for the car, of course; and Orme, with the uneasy feeling of one who has been trespassing, moved away toward the corner of the block. He looked back, however, and saw the newcomer clamber into the car and send it slowly up the drive. At the same time a light illumined one of the upper windows of the house. A shadow was thrown on the curtain. Perhaps it was the girl herself. What explanation had she given her friends for appearing so late at their door? Probably she had told them no more than that she was tired and belated. She was not the kind of girl from whom an elaborate explanation would be asked or expected. Then a thought startled him. Was this, perhaps, her home? No, she had spoken of the people who lived here as her friends, and she would not have tried to keep the truth from him by subterfuge. If this were her home and she had not wished him to know it, she would have requested him to leave her before they had come so far. It dawned upon him that it would not be hard for him to learn who lived in this house, and possibly through that knowledge to get a clue to her identity. His heart warmed as he realized how completely she had trusted him. His assurance that he would not try to find out who she was had satisfied her. And Orme knew that, if she had been so readily assured, it was because she had recognized the truth and devotion in him. With a happy sigh, he turned his back once and for all and walked rapidly away. But he did not go toward the electric-car line, which he knew must lie a few blocks to the west. Instead, he retraced the course they had come, for he had decided to visit the university campus once more and try to discover what had become of Maku, and more especially of the other Japanese, who had secured the papers. That he would be recognized and connected with the attack on Maku, was unlikely. When he came to the corner of Sheridan Road and Chicago Avenue, he hesitated for a moment. Should he go north through the campus and seek a trace of the Japanese who had escaped? Nearly half an hour had gone since the adventure among the trees, and the man must have got completely away by this time. Having the papers, he surely would not linger to learn the fate of Maku.
