I'm in the middle of a wonderful biography of Patricia Highsmith, "Beautiful Shadow" by Andrew Wilson. I have always liked the darkness in Highsmith's writings. My favorite titles are "The Story Teller," "This Sweet Sickness," the Ripley books, and "Strangers on a Train." There are many more interesting novels in her collection, too. What really strikes me about her writing is how much of it is based on a very dark interior life. Anybody who reads it will be rewarded with a glimpse into a writer's inner soul, where plots are based on pure attitude (and sometimes anger or even hatred) from her real self. She didn't hide her feelings, she let them show. Great book. Highly recommended to writers of all genres.
