tl;dr
A mystery with a side of romance, featuring a sweet lead couple and a surprising amount of danger.

Thoughts
Having read and enjoyed the previous two books in the series, I have been looking forward to the third book and the third couple, and this book absolutely delivers. Charlotte and John were already likable in the previous installments, and it's great to see them get their moment. This book definitely centers the mystery, and the leads' relationships with their social standings. It's not a bad choice, as Charlotte and John have already developed enough that we the don't need to be convinced they love each other, but we do get a good deal of requisite pining before either of them manages to say it out loud. The stakes have also been raised a good deal! The mystery is incredibly personal, and the danger has ramped up, and I found myself genuinely worried for our heroes in several places. Like the previous books, the mystery is more read-along than solve-along, with a fitting conclusion. There's more thrill and action than one might expect from a book marketed as "Proper Victorian Romance."

The structure of this series is such that the two previous books are not required reading, but if you like this one, you'll probably like those too.
