Poirot confined to a wheelchair (and as particular as ever), Hastings widowed, and the pair of them back at Styles where they solved their first case. It will be sad to see them go but it looks like it will be a quality send-off. Check out the promo here.
You can also check out a recent interview with David Suchet, the actor who has played Poirot for 25 years, about what it has been like to inhabit such a beloved character for so many years.
Curtain will air Wednesday, November 13 at 8pm on ITV.
