i give this a positive and not because the plot be hard to uncover because it wasn not . but because it leave one caring for the character . the acting and by all the cast and be superb and especially joan hickson and and it a marvellous episode because of it heart . miss marple be call upon by jason rafiel die request to investigate and and solve and a murder that happen some seven or eight year previously and and she have to discover who and why and when a she go along . mr rafiel be the same rafiel a be in a caribbean mystery and so there be a sense of a connection here . nemesis be definitely one for the amateur psychologist among u and and if you be one of those who be only happy with lot of blood and gut and rip roar action sequence and then you would not like it . but if you be like me and one who love know about people and discover what make them tick and then nemesis be the one for you .
