I've just finished the third Jack Caffery novel by Mo Hayder Called Ritual (EDITED) and will be reading Skin (edited) next , She has moved the action to bristol. At the end of the book she explains that she wanted to write a new character called flea who is a police diver , but then fitted in caffery by giving him a transfer. I did enjoy it despite the move, two more to go. As you can tell I'm excellent at remembering titles (EDITED).
