But it would have been nice if it was spelled out a little more. It wasn't slighted. It's worth dusting off these oldies. Charlotte is an investigator of sorts. She checks out men in historical England before women accept their marriage proposals.
Charlotte does feel responsible for the death.
So she sets out to investigate. Of course, they end up investigating together. The difference is, their personal relationship entwines with the suspense and ends up with a declaration of love and marriage. Happily ever after. From time to time, I happen upon a book from a lesser-known writer.
