The Eustace Diamonds by Anthony Trollope

The burden of his position was so heavy on Lord Fawn's mind that, on the Monday morning after leaving Fawn Court, he was hardly as true to the affairs of India as he himself would have wished. He was resolved to do what was right -- if only he could find out what would be the right thing in his present difficulty. Not to break his word, not to be unjust, not to deviate by a hair's breadth from that line of conduct which would be described as "honourable" in the circle to which he belonged; not to give his political enemies an opportunity for calumny -- this was all in all to him. The young widow was very lovely and very rich, and it would have suited him well to marry her. It would still suit him well to do so, if she would make herself amenable to reason and the laws. He had assured himself that he was very much in love with her, and had already, in his imagination, received the distinguished heads of his party at Portray Castle.

But he would give all this up -- love, income, beauty, and castle -- without a doubt, rather than find himself in the mess of having married a wife who had stolen a necklace, and who would not make restitution. He might marry her, and insist on giving it up afterwards; but he foresaw terrible difficulties in the way of such an arrangement. Lady Eustace was self-willed, and had already told him that she did not intend to keep the jewels in his house -- but in her own! What should he do, so that no human being -- not the most bigoted Tory that ever expressed scorn for a Whig lord -- should be able to say that he had done wrong? He was engaged to the lady, and could not simply change his mind and give no reason. He believed in Mr. Camperdown; but he could hardly plead that belief, should he hereafter be accused of heartless misconduct.
