Well, that is one unsettling story. I was looking for a short story to read with one of my English student after Roald Dalh's Lamb to the Slaughter (a great one) and remembered that Du Maurier's piece had inspired Hitchcock's movie (which I watched a long time ago). Her writing is to-the-point, which is nice for people who aren't perfectly fluent in English, but it has that eery atmosphere that makes the skin crawl. From what I remember, the movie is quite different in terms of characters and pacing. The short story starts really fast with horrifying images, but it manages to keep the tension until the end and I highly recommend it.
