I have read four Highsmith novels and really liked them, but my local library (which is generally crap) doesn't keep any. I've just read Strangers on A Train (what the hell did Hitchcock do to that plot?!) Edith's Diary, The Price of Salt, and A Suspension of Mercy, which I adored. I particularly liked the Suffolk setting. I want to buy some secondhand copies via Amazon or ebay, but need recommendations for her best books. Did she set any other novels in England?
