I love Agatha Christie books so much! Of the Poirot books I particularly liked Five Little Pigs, I think it was so interesting to solve a mystery decades later. Murder on the Orient Express is great too, a classic for a reason.

Of course the Poirot books are excellent, but if you’re ever in the mood for some good non-poirot Agatha christies, Murder is Easy is one of my favorites! And Crooked House - one of my favorite twists tbh.

And I don’t know if these are mysteries exactly, but The Mysterious Mr. Quin is a really interesting collection of short stories that I wish got more attention.
