A decent choice for some light reading. The duke in question needs to find out if Lady Eustace murdered his father, and pretends to court her daughter as a means to question the mother. The daughter has had a longstanding crush on said duke, there are a bunch of machinations, they‘re caught in a compromising position and marry. Mystery ends up solved, everyone is happy in the end. Part of a series, I picked up what I‘d missed. Entertaining.
