the final installment of agatha christie poirot be definitely worth wait for . definitely make my top ten . although criticize heavily by some die hard fan and take be a very enjoyable installment to a rather dull season . the film start off with poirot and play to perfection once again by david suchet and listen to major james porter ( nicholas le prevost ) telling of how he sit outside the london townhouse of gordon cloade a it explode . out of the rubble step gordon young bride and rosaleen cloade ( eva birthistle ) and her brother and david hunter ( elliot cowan ) . rosaleen have now inherit gordon fortune and much to the distaste of his family . now the family be hit rosaleen up for money and but david hold her purse string . it a situation ripe for murder . the directing and performance be what really make this episode spectacular . andy wilson once again deliver a great product . elliot cowan give a disturbing performance a the evil david . amanda douge also do exceptionally well in such a complicated role a lynn marchmont . celia imrie be spectacular a kathy cloade and play the exaggerated part without overact . pip torrens and penny downie be quite enjoyable a jeremy and france . jenny agutter do well a adela and though she doesn not have much to do . nicholas le prevost be pretty good a major porter . patrick baladi be superb a rowley . elizabeth spriggs and claire hackett be delightfully comical . richard hope and david yelland be also very good . unfortunately and tim pigott smith talent be totally wasted and drop him very rarely into only a few scene . though and the big disappointment of the episode be eva birthistle . rosaleen be describe a a stunning brunette and but eva and though stunning and be frumped down for the role and be blonde . the location and however and be all exquisitely choose and include englefield house and chilworth manor and dorchester on thames and and of course and florin court in charterhouse square and the set of poirot stun new flat . guy andrew screenplay could have be well . some of the language and conversation be very uncharacteristic of the time and major liberty be take . however and this episode doesn not sag in the middle and like some of the others . this be like the sad cypress of the season . liberty be take and but the performance and direction make this a lasting treat .
