“Other attempts appear as scars, weals, parentheses in conversation, absent days in his diary. But, at the same time, according to Stuart's weird sense of etiquette on such subjects, only one son in a family is allowed to kill himself, else it puts too much strain on the parents, and his brother, Gavvy, like Jacob in the Old Testament, has stolen Stuart's birthright.”

“I have a great sense of Stuart and silence on these nights. The village, wrapped in sleep; owls glide between the yew trees, badgers poddle across the graves. Then Stuart, cleaving the peacefulness. All people, gone. No educational experts, medical specialists, bullies, policemen. His mother's disapproval, hot on his heels, runs out of breath after half a mile. It is Stuart and the earth, just those two.”

“As his mother drove him away on the day he was let out, Stuart broke the cardinal prison rule: like Lot's wife, he looked back, at the building he'd just left.”

“If Stuart is a freak... it is because he has had the superhuman strength not to be defeated by this isolation. It is because he has had the almost unbelievable social adroitness to be able to fit in smoothly with an educated, soft-skinned person like myself and not make me frightened half to death. If Stuart's a freak, I salute freaks.”

“Revelation comes with these misunderstandings. Stuart's life and way of thinking momentarily exposed. Like a break in the hedgerow during the country lane part of a journey. For an instant you glimpse scenery you haven't seen before - fields of poppy and cornflower, trees gnarled in the shape of demons.”

“And so on, until you arrive at the other side, among the purely abstract self-harming: the grinding over your failures, the refusal to remember anything good, the determination to ensure - if anyone falls into the mistake of making it clear they actually like you - that the next time round they change their opinion pronto. Emotional self-cannibalism, in other words, like those tessellated pictures of a person grappling with a mirror image of himself.”

“Ruth once told me when I went to visit her at HMP Highpoint that it is surprising how much of what you imagine to be your innate sense of self actually comes from things that aren't one's self at all: people's reactions to the blouse you wear, the respectfulness of your family, the attentiveness of your friends, their approval of the pictures in your living room, the neatness of your lawn, the way people whisper your name. It is these exhibitions of yourself, as reflected in the people whom you meet, which give you comfort and your identity. Take them away, be put in a tiny room, and called by a number, and you begin to vanish.”
