Phil Rickman still - now it's number 6 in the series - The Prayer of the Night Shepherd which involves a spooky hotel, a small village and an alternative source of inspiration for Sir Arthur Conan Doyle's Hound of the Baskervilles. I remember being not quite so keen on this book when I first read it but I suspect that was because I read it in very small chunks. Some books need to be read in longish sessions I think.
I found The Lamp of the Wicked - number 5 in the series - compelling reading. The background to it the Fred West murder cases and a possible copy cat killer - with of course supernatural elements. A very good and thought provoking mystery.
