In celebration of Agatha Christie’s birthday and this month’s BCCC theme (and my entry for the BCCC Bingo), I’ll be going through my top 5 novels featuring one of my favorite detectives of all time – Hercule Poirot. Hercule Poirot is one of Agatha Christie’s most famous detectives. The Belgian detective was introduced to the world in 1920 and has since appeared in 33 novels, 51 short stories, and 2 plays.
