A number of years back, I read And Then There Were None. I really enjoyed the book and, seeing how it was my first Christie novel, I figured I should probably read some of her other books. Murder on the Orient Express was my introduction to M. Hercule Poirot, an eccentric Belgian detective. The quirky detective character made an otherwise average mystery into something more. While I didn't like it nearly as well as And Then There Were None, I found this book well paced, with interesting characters.
