I have just finished Salt Lane, the first book in the gritty detective series set around Dungeness in Kent. The Birdwatcher actually introduces Sargeant Cupidi but is classed as a standalone novel.
I was gripped by both books, both having a very different focus and I was so engrossed near the end of Salt Lane that when my OH brought me a cup of tea as Cupidi was trying to escape an event, I nearly jumped out of my skin!!
