[Patricia Highsmith] was overwhelmed by sensory stimulation - there were too many people and too much noise and she just could not handle the supermarket. She continually jumped, afraid that someone might recognise or touch her. She could not make the simplest of decisions - which type of bread did she want, or what kind of salami? I tried to do the shopping as quickly as possible, but at the check-out she started to panic. She took out her wallet, knocked off her glasses, dropped the money on the floor, stuff was going all over the place.

After reading Burgum, [Patricia Highsmith] wrote in her cahier that, like Kafka, she felt she was a pessimist, unable to formulate a system in which an individual could believe in God, government or self. Again like Kafka, she looked into the great abyss which separated the spiritual and the material and saw the terrifying emptiness, the hollowness, at the heart of every man, a sense of alienation she felt compelled to explore in her fiction. As her next hero, she would take an architect, 'a young man whose authority is art and therefore himself,' who when he murders, 'feels no guilt or even fear when he thinks of legal retribution'. The more she read of Kafka the more she felt afraid as she came to realise, 'I am so similar to him.

[Patricia Highsmith] was an extremely unbalanced person, extremely hostile and misanthropic and totally incapable of any kind of relationship, not just intimate ones. I felt sorry for her, because it wasn't her fault. There was something in her early days or whatever that made her incapable. She drove everybody away and people who really wanted to be friends ended up putting the phone down on her.It seemed to me as if she had to ape feelings and behaviour, like Ripley. Of course sometimes having no sense of social behaviour can be charming, but in her case it was alarming. I remember once, when she was trying to have a dinner party with people she barely knew, she deliberately leaned towards the candle on the table and set fire to her hair. People didn't know what to do as it was a very hostile act and the smell of singeing and burning filled the room.

[Patricia Highsmith] was a figure of contradictions: a lesbian who didn't particularly like women; a writer of the most insightful psychological novels who, at times, appeared bored by people; a misanthrope with a gentle, sweet nature.
