This is a historical fiction, written in 1930s and set around the year 1800. It features a young woman, Mary, who goes to live with her aunt and uncle after her mother passes away. She quickly works out that her uncle is hiding a lot of things at his inn, the titular Jamaica Inn. 

I really really enjoyed this; it was pretty suspenseful, and I was racing through the pages in my eagerness to discover what happens. In the age of thrillers and things being designed to grab our attention, I find this to be a very impressive achievement of du Maurier's. She really proves herself as a master storyteller in this book. I found Mary to be a wonderful character, really well-realised and consistent the whole way through.
