i have wait for age to comment on this programme and and felt it be about time some justice be do to it . this be one of christie darker and more sinister and engage work and not simply someone be kill for money and this be a dark and thoroughly engage tale of mystery and intrigue and love and murder and make all the good by the amendment make by the adaptor . the level of act be utterly superb and joan hickson be sublime in the part and a always . the rest of the cast and include the like of liz fraser and anna cropper and helen cherry all perform beautifully and but it my opinion that the show be steal by margaret tyzack and the closing scene between her and joan hickson be simply magical and the acting be as good a it get and chilling and moving and totally brilliant . please let me know if you agree with my word . i be seriously look forward to the remake to see how well geraldine mcewan version be . watch and enjoy .
