The cliffs, castles, bogs etc set such a good atmosphere for horror. The main character could live there or be on vacation there. I love all types of horror and enjoy a good mystery as well, so if you have any good mystery novels set there as well that are a little darker (psychological thriller, murder whodunit, etc). I did read While You Sleep by Stephanie Merritt and loved the atmosphere of it.
