"Margaret's third (or, techincally, forth) marriage would be a matter of business, a partnership that would years later be to some degree dissolved, by mutual consent, when need no longer required and opportunity offered. Nonetheless, it was a success story, with every sign that Stanley respected his wife's abilities."
