I really enjoy watching Agatha Christie's Poirot. Have you seen it?
I haven't seen it actually!  But, I have read Agatha Christie's Poriot's Early Cases.  It's a series of short stories she wrote back in the 70's.
Yes, the television series is based on her Poriot short stories; each episode was adapted from one of the stories.
Really?  Well I guess i learned something new today.  I still remember buying the book with pocket change I had saved up. It costs 2.25 euros.
