Larry's new problem was the most difficult and delicate dilemma of his life--this divided loyalty: to balk Maggie and the two men behind her without revealing the truth about Maggie to Dick, to protect Dick without betraying Maggie.

It certainly was a trying, baffling situation.
He had no such foolish idea that he could change Maggie by exposing her.

At best he would merely render her incapable of continuing this particular course; he would increase her bitterness and hostility to him.

Anyhow, according to the remnants of his old code, that wouldn't be playing fair--particularly after her aiding his escape when he had been trapped.
Upon only one point was he clear, and on this he became more settled with every hour: whatever he did he must do with the idea of a fundamental awakening in Maggie.

Merely to foil her in this one scheme would be to solve the lesser part of his problem; Maggie would be left unchanged, or if changed at all the change would be toward a greater hardness, and his major problem would be made more difficult of solution.
He considered many ways.
