18 (Mostly) British Mysteries to Binge-Watch This Winter

Watch if you're into: Period pieces, Agatha Christie, and the witty banter between a married couple who are also solving crimes together. This is a cute series that only lasted one season, but it's worth watching if you're looking for a show with a lighthearted Hitchcock-esque vibe.

How many seasons? One.

Where to watch: Watch Agatha Christie's Partners in Crime on Acorn TV.
