Book excerpt: Penelope Thornton-McClure and her bookshop's ghost-in-residence Jack Shepard are back on a new case in this delightful paranormal mystery from New York Times bestselling author Cleo Coyle. A big bestseller leads to small town trouble. Bookshop owner Penelope Thornton-McClure didn't believe in ghosts, until she was haunted by the hard-boiled spirit of 1940s private investigator Jack Shepard. Now Jack is back on the job, and Pen is eternally grateful... After an elegant new customer has a breakdown in her shop, Penelope suspects there is something bogus behind the biggest bestseller of the year. This popular potboiler is so hot that folks in her tiny Rhode Island town are dying to read it--literally. First one customer turns up dead, followed by another mysterious fatality connected to the book, which Pen discovers is more than just fiction. Now, with the help of her gumshoe ghost, Pen must solve the real-life cold case behind the bogus bestseller before the killer closes the book on her.
