Suzanne Morlett heads up a book club at the local library where she works. The members love a good mystery. Little did they know a dead body would turn up after Suzanne invites famous mystery writer Katherine Scherrer to speak to the group. Ms. Scherrer regales them with facts about mystery writing and then drops a bomb. She hints that she knows a secret one of them is hiding. This strikes home with several of the group members. A week later, the writer is found dead in her bathtub. Authorities treat it as accidental, but Suzanne doesn't believe in coincidences, and she launches an amateur investigation that nearly gets her killed.
