I think this is the weakest Poirot story yet to be filmed. A decent cast, well directed cannot disguise the flaws in the original writing. I bought it because I forgot to record it and it never seemed to be repeated, I know why now. Very briefly at a cards party the host is murdered. Who dunnit and why? Many of the suspects may have killed before and one has certainly killed again. Ariadne Oliver is in attendance moaning about her Finnish detecive. This is a reference to Christie moaning about Poirot. My copy of this disc has now been given to Oxfam
