Recs if you like An English Murder...

Shorter books (under 200 pages) that are part of at least one quest. Many are also in the public domain, making them easily accessible when you want to grind for that next badge.

on an island, snowed in, on a boat, aboard a moving train... this list is crime fiction -mostly murder mysteries- in which the characters are stuck in an isolated location and cut off from the outside.

disclaimer: i haven't read all of these so lmk if a book doesn't fit, and feel free to leave suggestions in the comments!

Mystery novels (and maybe a few thrillers) that have a theme of Christmas or other winter holidays, or an overall wintery theme. Please give suggestions!
