Evil under the moon

Sisters Andrea Flynn and Kathleen Williamson are volunteers with the Baxter County Sheriff's Office, and they are determined to solve the murder of Lea Logan, a young waitress at the Martindale Country Club. It appears Lea might've been the mistress of a local big shot, but did that contribute to her death? The murder happened nearly five years earlier, and now the sisters must jog fading memories and scramble for clues in a case gone cold. Soon they discover the long-dead body of a second victim, but complications in the form of password-protected computer files and a bugged office prevent them from identifying the killer. Andrea and Kathleen are persistent, but can they solve the case without putting their own lives in jeopardy?
