The Turquoise Dagger

Running a bookstore can be MURDER
Derek and Camellia Collins own The Turquoise Dagger, a mystery bookshop in Arizona. When the television series, Famous American Mysteries, comes to town to investigate a local cold case, Derek and Camellia are lured into the hunt as a publicity stunt. It all seems a game until the bodies start piling up, as the killer puts the Collins' and their nosey cocker spaniel, Merlini, in harms way.
