this bbc version of an agatha christie book show the pitfall of follow a book too closely . christie book tend to move at a gentle and sometimes even sedate pace and and evans be one that certainly do . it also have a solid school of red herring to confuse the plot . this version be extremely faithful to the book and which result in a very slow and involved story . a a christie fan and i give it 7 star and but it take 3 hour to make it way through a relatively action free story . i appreciate some of the tightening of plot that the bbc do for it late christie production much more . in the end and this movie be a leisurely pleasure and highlight by the breathy waif francesca annis who bring considerable charisma to her role and play off james warwick very well .
