Whosoever Shall Offend by F. Marion Crawford
When the widow of Martino Consalvi married young Corbario, people shook their heads and said that she was making a great mistake. Consalvi had been dead a good many years, but as yet no one had thought it was time to say that his widow was no longer young and beautiful, as she had always been. Many rich widows remain young and beautiful as much as a quarter of a century, or even longer, and the Signora Consalvi was very rich indeed. As soon as she was married to Folco Corbario every one knew that she was thirty-five years old and he was barely twenty-six, and that such a difference of ages on the wrong side was ridiculous if it was not positively immoral. No well-regulated young man had a right to marry a rich widow nine years older than himself, and who had a son only eleven years younger than he.
