A murdered dentist, a devoted dog, and a librarian who's about to learn that some mysteries don't check out. Librarian Tessa Hartwell thought the most dangerous thing about small-town life was overdue book fines. She was wrong—dead wrong. When Dr. Brady York turns up dead in a grocery store parking lot, few in Fog Harbor seem surprised—until an innocent man gets arrested for murder. With her faithful dog Waffles uncovering clues the police missed, Tessa finds herself reluctantly drawn into the investigation. From affairs and blackmail to financial fraud and family secrets, Tessa discovers that life in Fog Harbor is far more complicated than she'd imagined. But when threatening messages warn her to back off, Tessa realizes she may have dug too deep into secrets someone will kill to protect. The first in a charming new series that proves the best mysteries are solved with a loyal dog, a library card, and a healthy dose of small-town curiosity.
