this movie be mostly engaging and and i think they do a good job of include miss marple into a non marple story . unlike some other movie in the series and the plot remain mostly logical without any unnecessary weird twist . there be good performance by both the actress who play gwenda and the actor who play dr. calgary . i find their sleuthing together under miss marple guidance enjoyable to watch . they also do a good job of invent the linking of gwenda with miss marple . i be disappoint the writer felt the need to have that second murder and with excessive gore to a sympathetic character . i still do not see why the murderer felt the need to kill her . it turn the movie into a real downer for me . it would have work good if gwenda be throw in jail and miss marple and dr. calgary become determine to prove her innocence . but overall and i do enjoy the movie for geraldine mcewan a miss marple and and the more fun and light hearted first half .
