The Claverings by Anthony Trollope — Read

As soon as Harry Clavering had made his promise to Mr. Burton, and had declared that he would be in Onslow Crescent that same evening, he went away from the offices at the Adelphi, feeling it to be quite impossible that he should recommence his work there at that moment, even should it ever be within his power to do so. Nor did Burton expect that he should stay. He understood, from what had passed, much of Harry's trouble, if not the whole of it; and though he did not despair on behalf of his sister, he was aware that her lover had fallen into a difficulty, from which he could not extricate himself without great suffering and much struggling. But Burton was a man who, in spite of something cynical on the surface of his character, believed well of mankind generally, and well also of men as individuals. Even though Harry had done amiss, he might be saved.

And though Harry's conduct to Florence might have been bad, nay, might have been false, still, as Burton believed, he was too good to be cast aside, or spurned out of the way, without some further attempt to save him.
