Set in the 1930s, a time when Britain is dangerously divided and suspicion and hatred are on the rise, the story sees Poirot face a serial killer known only as A.B.C. As the body count rises, the only clue is a copy of The ABC Railway Guide at each crime scene. Poirot's investigations are continuously thwarted by an enemy determined to outsmart him. If Poirot is to match his nemesis, then everything about him will be called into question: his authority, his integrity, his past and his identity.
Rightly or wrongly this was a story inspired by the original Agatha Christie novel rather than the story itself. Yes it was very different BUT I still found it very watchable. I watched it over 3 consecutive nights and wanted to watch to the end despite knowing 'who dunnit'. I was intrigued to find out about the demons Poirot was wrestling with from his past. It was a tad overlong though, I think two episodes with less padding might have been better, and why they didn't just make something similar with a new detective we didn't know is unfathomable as they made it almost unrecognisable anyway. It would have worked just as well as I thought John Malkovich was very good.
