The Sound and The Furry - A Marcia Banks and Buddy Mystery, #6

A tropical paradise turns deadly. Service dog trainer Marcia Banks had thought it was the perfect arrangement-stay on her client's private Gulf-coast island and get the human phase of the training done more quickly, while enjoying a much-needed break from the chaos of house renovations back home. This certainly wasn't the tranquil getaway she'd envisioned, however. Two resident ghosts, a sour-puss housekeeper and bearing witness to her client's shaky marriage are bad enough.
But within days, she's discovered even deeper and darker layers of dysfunction. Via emails and static-filled phone calls, fiancé Will Haines convinces her to get herself and her dogs out of there, but before Marcia can accomplish this, a late-season hurricane abruptly changes course and strands them on the island... with a murderer.
