I would consider one more book, this one was slow to start and hard to get into.
Yes, great book, a lot of detail
Lots of background info about the townspeople. Suspenseful, not just who the murderer is but if the heroine can stay in town.
There are many reasons why a book might be unavailable.
Sometimes a book goes temporarily out of print - and sometimes no audio version has ever been recorded. Audible wants to give you the most complete selection we can and we'll keep adding series and filling in gaps as quickly as possible.
This is a great book. It started with action and kept it up through the entire book. This is the best in the series, so far.
