Query: A Nice Surprise

With the increased popularity of the historical novel (non-romantic), this book is a nice addition to the mystery genre. Ms. Gleeson writes well and captures the period allowing the reader to enter the story and concentrate on the mystery. Though the middle gets bogged down a bit and the ending is only satisfying, I would like to meet some of these characters again.
