A poisonous person, Patricia Highsmith was an enduring writer

PATRICIA HIGHSMITH had a thing for snails. She admired their self-sufficiency and found it “relaxing” to watch them copulate, delighted by the impossibility of distinguishing male from female. She collected them for decades, keeping hundreds at home and scores in her handbag, which she let loose when bored at dinner parties. Her affection for snails was matched by her ambivalence towards people, whom she often found baffling and kept at a distance. When a literary agent suggested Americans didn’t buy her books because they were “too subtle” and the characters too unlikeable, Highsmith responded: “Perhaps it is because I don’t like anyone.”
