Murder by Decay (Edna Davies mysteries) (Volume 6)

Edna Davies is distressed. She is suffering from the worst toothache she can remember, and her dentist can’t help her. He is the prime suspect in a homicide, and his office has been sealed off as the crime scene. His guilt would mean he purposely led Edna into a trap, an act of betrayal she will not accept. As she attempts to learn the truth, she stumbles into a web of intrigue dating back ten years. With the help of a little stray terrier, she finds her answers, but nearly loses her life in the process.
