Nigel Pritchett was the first murder victim in Throckmorton since 1934. When Margo Monroe gets a message from him on the day of his funeral, she is concerned but not terribly surprised--she's a professional ghost hunter, and her boss was the late professor's oldest friend. While Margo and her team set out to find out what happened to Professor Pritchett, they also find time to help a precocious fifth grader named Chester, who claims his school is haunted.

Margo soon finds herself embroiled in more than she bargained for. Her job is to find out what happened to the late professor, before she ends up as a ghost herself.
