“Disobedience is one of the few tricks you have left to hang on to the idea that you continue to exist distinctively and are still reliably connected to the person who bore your name on the outside.”

“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.”

“And it is strange: a few moments after the cars that brought us down drive off, I become aware that already I have discovered something new. Because we do not have a place of our own, nor will have for the next three days, we must invent one. I catch myself, and the eyes of one or two others, searching for a section of the pavement with which we might want to become familiar. We are looking among the concrete slabs for the outline of a home.”

“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.”

“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.”

“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.”

“For a moment, I believe, there was a stillness. A shocking realization by all things - beetles, dormice, the spiders spinning their webs in the moonlight, even the hot metal of the tracks and the wind in the trees - that Death had just shrieked past like a stinking black eagle and made off with a remarkable man.”
