His three latest detective novels are BRILLIANT! They feature DC Fiona Griffiths, living and working in Cardiff. She is entirely her own character, but has aspects of the wonderful Sara Lund from The Killing, and of Lisbeth Salander, the heroine of the Stieg Larsson (Girl with the Dragon Tattoo) trilogy. Fiona is unconventional, partly because she was very ill as a teenager with Cotard's syndrome - 'It took quite a long time to develop Fiona, but the thing that locked everything in place was her Cotard’s Syndrome, an illness where sufferers believe themselves to be dead. It seemed to me that the condition was perfect for a crime story. It’s a mystery in itself. It walks a dark edge between life and dark. And it places the detective herself as the ultimate outsider.'

There are three Fiona Griffiths novels so far - Talking to the Dead, Love Story, With Murders and, just about to appear, The Strange Death of Fiona Griffiths. I have found each more compulsive than the last.
