Quinn Victoria Caine is back in her quirky town of Vienna, Virginia, starting her new life as a bookbinder in her family bookshop. Her ex-boyfriend is due to marry her high school nemesis Tricia—which is really annoying—but it isn't Quinn's fault when Tricia is found dead in the road. With her trusty German Shephard Ruff Barker Ginsburg by her side, Quinn gets help from her cousin—a lock-picking nun—to solve the case before she gets hauled in for murder.
