Key Lime Pie Murder, by Joanne Fluke

It's happening again in Eden Lake, Minnesota, home of Hannah Swensen's "Cookie Jar" cookie and coffee shop. This time Hannah is a judge at the Tri-County Fair, and when one of her fellow judges, the local home economics teacher, is murdered, Hannah is--as usual--on the case! The eighth in this easy-going, easy-reading series is cozy fun as the reader follows Hannah and her two boyfriends, her business partner, and her family.
