A stray dog leads bookseller Penelope McClure and her gumshoe ghost on a chase for a clever killer in this brand-new entry in the “utterly charming” (Mystery Scene) Haunted Bookshop Mysteries from New York Times bestselling author Cleo Coyle.

Pet Mystery Week brings brisk business to Penelope’s Rhode Island bookshop, but a real mystery comes barking at her door when a lost dog turns up in a panic. Pen and her son Spencer follow the furry fugitive to a wooded area where the dog’s owner lies unconscious. Mrs. Cunningham is a warm-hearted widow who volunteers at the animal shelter and runs Buy the Book’s pet lovers book club. Why would anyone shoot such a sweet soul?

The police believe it’s an accident, a shot by a careless deer hunter, but Pen remains skeptical.

Jack has a dog story of his own, a case from the 1940s that may help Pen sniff out clues to her present predicament.
