Historical mysteries seem to be all the rage at the moment, and fortunately, publishers have yet to monetise and ruin the trend to such a degree that you can't find a selection of well written series to enjoy. While the quality of cozy mysteries has been abysmal the last several years, Historical Mysteries have filled in the gap nicely for me.
A Lady's Guide to Mischief and Murder is the 3rd in a series I discovered at my first (and so far only) Bouchercon convention. It's a good series, and this book is a strong 3rd book, moving the characters' arcs along quickly, while presenting an interesting stand-alone plot, with clues easily missed and writing that skilfully misdirected the reader down several false avenues. As the story moved along, some of the misdirection became obvious, but some of it didn't, rendering a delightful mystery well done.
My only groan over the book was the introduction of Countess Harleigh's mother who was caricatured for most of her page time, only to do the whole mama-lion thing and achieving what to me was an insincere redemption in the final pages. Fortunately she's not around much in this book and it wasn't enough to really weight the book down.
