I didn't want to see Poirot die, but if he has to die, this is the way for him to go. Hunting a criminal with his best friend Hastings. It definitely reminds me of the "death" of Sherlock Holmes pursuing his greatest enemy, Moriarty. The plot was complex, and there are many reasons to suspect everyone of murder. And it has a satisfying ending. Any Poirot fan will want to read this since it brings back lots of Poirot/Hastings memories and ties up some loose ends.
