A Bone to Pick (Aurora Teagarden Mysteries)

Aurora "Roe" Teagarden's fortunes change when a deceased acquaintance names her as heir to a rather substantial estate, including money, jewelry, and a house complete with a skull hidden in a window seat. Roe concludes that the elderly women has purposely left her a murder to solve. So she must identify the victim and figure out which one of her new, ordinary-seeming neighbors is a murderer-without putting herself in deadly danger.
