Best paranormal books for the dark season—recommendations?

Right, I'm settling in for a proper winter of reading and I want recommendations for books that are genuinely creepy without being American schlock. The dark nights are making me want proper, unsettling reads rather than the usual UFO documentaries.

What's everyone's go-to for autumn/winter paranormal reading? I've already done most of the standard stuff - Whitley Strieber, Jacques Vallée, the obvious ones. But I'm looking for either British-focused paranormal research or just genuinely good writing about the weird.

Bonus points if it's available in paperback because my Kindle battery drains mysteriously fast (might be haunted, who knows) and I like having actual books during power cuts.

Cheers in advance!

'The Fortean Murders' by Chet Williams is brilliant - less known than it should be, proper dark. Also anything by Jeremy Dyson if you can get it. He's involved with The League of Gentlemen and his paranormal essays are genuinely unsettling in a way that doesn't rely on jump scares.

For British-specific stuff, 'Mysterious Britain' by Janet and Colin Bord is the classic but if you want something more recent, look up anything by Paul Devereux about landscape and anomalies. Not always easy to find but worth hunting for.

'The Dunwich Horror' and other stories - I know Lovecraft is American but he was writing about New England which has that same grim, isolated, old-world-secret-keepy vibe that you get in the UK. If you want actual UK paranormal research, honestly most of it's in scattered papers and local histories. Try asking on here - someone will know the good obscure stuff.

Peter Underwood's books on haunted places are excellent and very British. Borley Rectory stuff especially. Also if you can find old copies of 'Prediction' magazine or journals from the Folklore Society, that's where the real research is. Libraries sometimes have archives.

'The Electric Monk' by... no wait, that's Douglas Adams being silly 😂 But seriously, have you tried Robert Kirk's 'The Secret Commonwealth'? It's 17th century but it's about fairy folk and the hidden world in Scotland. Genuinely eerie and it's the basis for a lot of modern paranormal thinking.
