Got his latest for Christmas, A Private Cathedral, and I'm really not sure about it. It's very 'woo'. The writing was beautiful (and very harsh in some places) as usual, but the story line just didn't seem right for me. He's used supernatural themes in some of his other books, but not (I don't think) in the Robicheaux books, and I'm not sure I like it!
Happy to be dissuaded though.
