Larkin’s words told that the trying journey was over; but as the seconds went by, Margaret began to feel worried again.

She was sorry that she had come on this amazing visit. At first the experience had been interesting, but now it was too much so.

She had no idea where she might be. Not only had she become lost in New York; she was also totally confused in regard to the building they had entered.

She did not know whether they were below the level of the street, or above. She decided that they might be above — but how far?

She began to think of her uncle, back in the old house. Had it been right for her to leave him there, alone?

Then she half smiled at her own thoughts. At least her uncle knew where he was, while she had no idea of her location. Margaret looked at Larkin; the secretary caught her smile and returned it. That was better!

After all, Larkin knew what he was about, and she felt that she could trust him.

“Look!” said the secretary.

The side of the room was opening — half going downward, half upward. Margaret had not noticed the break in the center of the wall. The spreading portions disclosed an oak-paneled anteroom, with a door at the other end. That, the girl felt, was helpful.

She stepped forward with Larkin, and turned to watch the wall of the moving room close behind them. Larkin stood looking at the door ahead. The girl was sure now, that he had been here before. Her gaze joined with his.
