This is book 4 in Bingham's Fiona Griffiths series. Fiona is a police officer in Cardiff, Wales and she's quite the character. She has an interesting background (abandoned then adopted as a child, suffered a bizarre mental episode in her teens, father is an alleged criminal though never convicted) and she has an outside-the-box way of thinking. In this latest installment, an archaeologist is found beheaded and her body pierced by three spears. There are very few clues to go on but soon Fiona is on her way to figuring things out with the help of her new friend Katie and a vicar. The murder mystery focuses on Arthurian legends, which I mostly found fascinating although sometimes it got a little tedious. The ending was different in that the main criminal who did the dirty work was caught and arrested on the page but the mastermind behind the crime was arrested off-page in a throwaway line.
