This slim volume reminds me of older works by authors like Sabine Baring Gould and Montague Summers. It's definitely classic folklore explicated by pro folklorists but it rarely veers into the language of academic folklore, maintaining a conversational tone and ranging freely among topics related to each chapter's theme. Each chapter is an essay unto itself but if the book has a central thesis, I missed it. The essays are fun, lively, and informative. My favorite chapter was on "Folk Ghosts," mostly because it was educational for me to read how folklorists differentiate varying types of ghost story. The section on phantom carriages resonated especially with my interest in American car ghosts and ghost roads. Other chapters, on Urban Legends and Dark Tourism, felt unduly aimed at trendy topics that have been hashed over in many places recently.
On the whole, a book worth the time to read it for anyone with an interest in ghost lore, the darker side of churches in the British Isles, hags/nightmares, Slenderman, and legend tripping but by no means essential.
