All this while Maggie, and what he was to do about her, and how do it, was in Larry's mind.

Even this work he was doing for Miss Sherwood, he was doing also for Maggie in the hope that in some unseen way it might lead him to her and help lead her to herself.

There were difficulties enough between them, God knew; but of them all two were forever presenting themselves as foremost: first, he did not dare go openly to see her; and, second, even if he so dared he did not know where she was.
When he had been with the Sherwoods some three weeks Larry determined upon a preliminary measure.

By this time he knew that the letters mailed from Chicago, according to the plan he had arranged with Miss Sherwood, had had their contemplated effect.

He knew that he was supposed by his enemies to be in Chicago or some other Western point, and that New York was off its guard as far as he was concerned.
His preliminary measure was to discover, if possible, Maggie's whereabouts.
