Death overdue

the long version

Carrie Singleton is just about done with Clover Ridge, Connecticut. Then she's offered a job as the head of programs and events at the local library-- which comes complete with its own ghost. Her first major event is a program presented by retired homicide detective Al Buckley, who claims he knows who murdered Laura Foster, a much-loved part-time library aide who was bludgeoned to death fifteen years earlier. As he invites members of the audience to share stories about Laura, he suddenly keels over and dies. He was poisoned-- and Carrie feels responsible. She's convinced he was murdered by the same man who killed Laura all those years ago. Luckily for Carrie, she has a friendly, knowledgeable ghost by her side.
