Kathleen Paulson enjoys her life as a small-town librarian with two extraordinary cats, Owen and Hercules, who provide companionship during the quiet times and have a remarkable talent for sleuthing when murder disturbs the peace....   The local businesses of Mayville Heights hope to convince Chicago-based company Legacy Tours to sell a vacation package for their town. Legacy Tours partner Mike Glazer grew up in Mayville Heights, but he’s no longer the small-town boy people once knew. Even the local bootlegger has an issue with the bossy loudmouth Mike has become—until someone shuts him up for good.   When Kathleen discovers Mike’s body on the boardwalk, she can’t help but get involved in the investigation—even if her beau, Detective Marcus Gordon, would rather she didn’t. Now, with a little help from Owen and Hercules, it’s up to Kathleen to make sure the killer is booked for an extended stay in prison before someone else takes a permanent vacation.
