Although the fifth of the Detective Karen Hart adventures, it was this reader’s first encounter and thus more a standalone crime mystery. The story begins with a couple out walking of an evening at a Christmas Market, unaware they are being watched. A scream from the Lincoln Cathedral begins the murder investigation with a macabre signature left marking the victim. As the investigation evolves, other issues, including possible police force corruption or a seemingly unsolvable car crash arise. A gripping police procedural with great characters and engrossing mystery that deepens as the danger and body count mounts. It’s an outstanding crime novel with a minimum four-star must-read rating.
