Today's research took me to Wistman's Wood on Dartmoor, which is close to a character's home. It's one of only three ancient copses on the moor and is the oldest in Devon. Its gnarled, stunted oaks, verdant fern and lichen engender a mystical, eerie feel, and as you clamber over the sprawling roots and mossy prehistoric boulders, the finger-like branches seem to reach out and grab you.
Apparently, after dark, the Wisht Hounds chase sinners through the woodland.
I also had to research a nearby pub. For authenticity's sake.
