I used to love to read Agatha Christie novels. I also love the TV show Poirot, based on her detective character.
That show lasted a long time.  It aired on ITV from 1983 to 2013
I didn't realize it ran that long - must have missed some episodes. He's such a funny little man - what a great imagination AC had!
David Suchet did a great job playing Hercule Poirot
