i have to say when it come to book to movie adaptation the bbc rarely let me down . now regard this mini series . i love the starling novel and it by far the best murder or mystery i have ever read . the mini series and it defiantly make my day when i saw it . the primary story be keep near perfectly intact . the character match the one to the novel very well and the personality and mannerism be spot on for red and jez . i think duncan be do very well a be kate and eric come off a too much of a simplistic character and he have a little more depth in the book and but they also alter his sub story so that may have have to deal with it . of course there be change and but most be cosmetic and but some i find disappointment in and the sub story with eric murder charge be change and that change the whole dynamic between red and eric for the movie and and they cut out the triathalon training jez be do . some of the other event in the book be change to be viewer friendly . over all if you like the book and you will like this and if you like the mini series and then you will love the book . i must say and this be the most accurate book to movie adaptation i have see .
