A Bone to Pick (An Aurora Teagarden Novel) - Charlaine Harris

Aurora Teagarden: 2 There's nothing like discovering that an elderly lady has made you the unlikely heir of her estate to add excitement to your life. Except perhaps finding a human skull in the window seat. Roe Teagarden is sure that Jane Engle wasn't a killer. Which means the real murderer is still out there. And now it's up to Roe to identify the victim and work out which one of Jane's seemingly ordinary neighbours is in fact a cold-blooded murderer - without putting herself in deadly danger.
