Query: Agatha Christie's Poirot Series 1

Of all of Agatha Christie's characters, Poirot is our favorite. We watch and re-watch these stories. The Brits know how to tell a good murder mystery. We enjoy the period settings, costumes and automobiles, and particularly the development of the characters. We wish there were thousands of Poirot mysteries. We never tire of them.
