I was pleasantly surprised by Helle and Death. If you took the characters from The Secret History (yes, the same ones that are hugely unbearable to be around) and put them in an Agatha Christie novel complete with spooky house, old scores to settle etc, you'd get this book and actually, I kind of enjoyed it. I can see how people wouldn't enjoy this - the middle is particularly treacle-like to get through - but the ending more than makes up for it. I didn't see it coming and that's one of the best ways to get me to enjoy a mystery.
