From back of book: The First Aurora Teagarden Mystery.
Lawrenceton, Geogia, may be a growing suburb of Atlanta, but it's still a small town at heart. Librarian Aurora "Roe" Teagarden grew up there and knows more than enough about her fellow townsfolk, including which ones share her interest in the darker side of human nature.

With those fellow crime buffs, Roe belongs to a club called Read Murders, which meets once a month to analyze famous cases. It's a harmless pastime--until the night she finds a member dead, killed in a manner that eerily resembles the crime the club was about to discuss. And as other brutal "copycat" killings follow, Roe will have to uncover the person behind the terrifying game, one that casts all the members of Real Murders, herself included, as prime suspects--or potential victims.
