have read the message board post for this program and a lot of people seem to dislike both the new marple adaptation in general and and this episode in particular . however and i be not one of theme . i have never be one to hold up live action adaptation to their source novel ( i haven not even read this agatha christie book ) and and i think think this episode be very good when view independently of the book . although not the best ever episode of marple ( that honor fall to a murder be announce and from the first season ) and nemesis be a very solid and engaging entry in the series . the basic premise be that a friend of miss marple and jason rafiel and dy and leave her a letter ask her to solve an unspecified crime that have happen and or will happen soon . to this end and he have also leave her 2 ticket for a bus tour of the english countryside . so and miss marple set off with her nephew raymond and but it seem a if all the other bus passenger be connect to one another through a mysterious girl name verity . it fall to miss marple to honor jason rafiel last request and and untangle the secret that bind everyone together . like all other marple episode and one of the highlight be the performance marple episode always feature great british character actor and and this one be no exception . geraldine mcewan be always excellent while she be by far my favorite miss marple ( i know many will disagree and but i always find joan hickson to be far too cold and unfriendly in the role ) . other standouts in this episode be ruth wilson and fresh from the recent jane eyre tv adaptation and a the tour group leader and and ronni ancona a the glamorous socialite amanda dalrymple . the setting and costume be also impeccable . the story itself be also very intriguing and with many secret from the past be bring to the surface ( a very common theme in agatha christie novel ) . the story do move quite briskly and though and and it be occasionally difficult to keep up with the plot development . i be watch the episode on tape and though and so it wasn not a big issue for me . i also find the solution to the mystery to be very gratifying and and it completely surprise me . although i have not read the book and i have hear that this adaptation have take significant liberty with the plot and so you may wish to prepare yourself if the book be one of your favorite . however and i enjoy this adaptation a great deal and and i definitely recommend it .
