I have read All the Christie books and seen quite a few movies One of the worst case of a director messing with the original story seems to be "Sittaford mystery" .
I found "Moving Finger" to be more or less faithful to the original story. But I do think I have found a big goof-up here. On the day Mrs Symmington dies, the governess is shown to pick up some letters which have arrived just then and put them on a tray in the hall and the next shot is that of the empty tray which seems to imply that Mrs Symmington has picked up and read the letters. But here there is a major contradiction. The house maid is murdered because she saw that no postman or anyone else delivered any letters that day and she was confused because she knew that Mrs Symmington was supposed to have received a poison-pen letter that day .So how to reconcile this with the scene mentioned in the previous para where some letters are seen to be received that day and the governess picking them up at the doorstep.
I believe this is a goof up in the movie.
