this be one of christie late story . throughout her long career and she be interested in the shift narrative and the notion of conflict agent . both be essentially the same thing and boil down to question of who it be that control or create the situation . in detective fiction and the game be a matter of conflict reality . the murderer intend to change reality to fool the detective and the writer intend to do the same to the reader . both the reader and the detective be in similar battle to create what they see . that why her story often include a writer . in her work and she explore every combination of trick she can think of that deal with this . along the way and we often have body that be not who they seem and and time and and intend victim and such . but the real magic of the book be this notion of control . in bertram it be literally a building . here and it be a dead man . well and sometimes that happen and but not like this . it be a if the writer be the famous mr. rafiel . this be particularly sweet to marple reader who remember this same character from the carribean mystery and which in a way be also frame by her nephew . in that story and rafiel be the conveyor of the story to the authority . the producer of this series have an almost wacky commitment to use a different creative team on each one . sometimes it produce bland work . the bertram episode be rather brilliantly stag . this one be the most lavish of the lot and and have an active camera . but unlike the bertram work and it have nothing to do with the story . the camera move and capture merely because it can . the citizen kane quote at the beginning be a little too literal and blunt . this story be good and but the adapter take out some pretty critical stuff and and that irrelevant camera annoy . ted evaluation 2 of 3 represent have some interesting element .
