In the midst of a bad drought, the shores of a local lake recede to reveal an old abandoned car. Megan is intrigued by the Depression-era jalopy and puzzled when her fellow amateur sleuths would rather get back to discussing Agatha Christie. Then bodies start popping up all over town, ritually murdered, and current crimes take precedence over old secrets. It's Megan who discovers the corpses, making her the prime suspect. To clear her name, she'll need to find the killer - who's obviously been boning up on Christie novels. Is Megan reading too much into clues, or could the culprit be a book club member?
