Being shoved out of a castle tower is a terrible way to die.... Jill, Marie, Angela, and Jo wonder why Nick is late for their meeting in a Welsh pub on the first day of their vacation. He lives in Amsterdam and is always on time. Jill feels a sense of dread when she sees two men in suits enter the pub and ask the bartender a question. Jill Quint, MD, forensic pathologist, PI, and vintner leads a group of friends in solving crimes. She's assisted by friends from Wisconsin who have essential skills to any investigator. Namely, Jo is the resident financial wiz, Marie is a social media maven, and Angela manages to get the right photo at the right time. A new police force enters the inquiry once they cross the border into Scotland. Jill's team starts their search for Nick's killer. The mystery follows them through Wales and on to Edinburgh as the team tries to figure out just who Nick's real identity. He's not who they thought he was, and so is that the key to his murder? The Welsh police are happy to see the Americans go away while the Police Scotland wishes they would go home. Along the way, Jill and the team find danger, and the DIs are pulled into an investigation that dates back to the end of WWII. Read about the misadventures of the four women in CASTLE KILLING, book 7 of the Jill Quint, MD Forensic Pathologist series.
