This, the fourth in the Mallory series, was a thoroughly engrossing read. Ms. O'Connell's character development is exceptional. The plot is intricate without being overly busy. This book did cause me an embarrassing moment. The scene where Mallory is reunited with her very old dog triggered uncontrollable sobs which proved to be rather disconcerting for the people around me in the dentist's waiting room. There were a few chuckles too. When Detective Sergent Riker meets Sheriff Tom Jessop, it's a match made in heaven. You could probably read and enjoy this book without reading the previous books in this series, but I think you would be missing out on a lot. All of Ms. O'connell's books to date have been very good.
