The Pale Horse by Agatha Christie
Okay, so Agatha Christie isn't exactly scary but I love the atmosphere this book creates. I first read this novel on my first ever trip around the UK, so it has a special place in my memory. It tells the story of the sinister goings on at The Pale Horse Inn, home to three unusual ladies- a physic, a medium and a witch- and their involvement in the deaths of Father Gorman and Thomasina Tuckerton.
I get goose bumps at the mere mention of this book, it still gives me the heebie jeebies even though I've read it a few times. It has perhaps been more popular in recent years after Daniel Radcliffe starred in a movie adaptation that terrified me (as in I had to mute it and cover my eyes for some parts and couldn't sleep afterwards). It has all the factors needed in a good scary story- an English moor, a young sensible hero that doesn't believe in anything supernatural, a scary abandoned house and a now deceased crazy old lady. Trust me it's genius, but you may need to sleep with the lights on afterwards.
Nothing sums up the perfect scary story for me quite like the poem 'The Raven' by Edgar Allan Poe. I admit, some of his stuff is tough reading, but once you understand it you realise how genius it actually is. Tales of Mystery and Imagination is a collection of some of his best short stories and poems. This edition comes illustrated which for me helps to explain some of the more complicated prose. It is true Victorian horror.
