I thought the introduction by Diana Rigg was fascinating. It's prompted me to read more of the author's works. The film was rather slow moving. The relationship building between Lucy and Robert wasn't there really but it was a delight on the eyes and captured the era in costumes and scenery beautifully. There weren't any real twists but it was an interesting story. Characters (the maid) were brought in, then used and dropped. Needed a bit more fleshing out. Worth watching though.
