Other People's Money by Emile Gaboriau

We have every species of courage in France, and to a superior degree, except that of braving public opinion. Few men would have dared, like Marius de Tregars, to offer their name to the daughter of a wretch charged with embezzlement and forgery, and that at the very moment when the scandal of the crime was at its height. But, when Marius judged a thing good and just, he did it without troubling himself in the least about what others would think. And so his mere presence in the Rue. St. Gilles had brought back hope to its inmates. Of his designs he had said but a word, -- "I have the means of helping you: I mean, by marrying Gilberte, to acquire the right of doing so."

But that word had been enough. Mme. Favoral and Maxence had understood that the man who spoke thus was one of those cool and resolute men whom nothing disconcerts or discourages, and who knows how to make the best of the most perilous situations.
