When a visiting author is murdered, bookshop owner Penelope Thornton-McClure and her ghostly companion must spook out the devious killer in this Haunted Bookshop mystery from Cleo Coyle, writing as Alice Kimberly.

The only rule bookshop owner and widow Penelope Thornton-McClure has given ghostly hard boiled P.I. Jack Shepard is to not haunt the customers. But when hot, young author Angel Stark arrives at the store to promote her latest, a true crime novel, Jack can hardly contain himself.

Angel’s book is an unsolved mystery about a debutante found strangled to death. And it’s filled with juicy details that point a finger at a number of people in the deb’s high society circle. But when the author winds up dead too—in precisely the same way—Pen is fast on the case...which means Jack is too. After all, a ghost detective never rests in peace.
