Tentatively I stood a great lump of wood on the chopping block and bought the axe down on it. It flew into two perfect halves. Such was my elation that I ran inside, put on our ancient cracked record of Aretha Franklin singing Respect and danced all by myself for half an hour in our living room, without inhibition, almost crying with jubilation – not just about the wood, but because I could live competently some of the time, and because that day I liked myself.

To slide into the domed reading room at ten each morning, specially in summer, off the hot street outside, was a sensation as delicious as dropping into the water off the concrete edge of the Fitzroy Baths.

It's a terrific privilege to be able to see into somebody else's life.

But I now think what I was doing, in a completely unconscious way, was getting off the turf where my husband and I might be rivals. We were both working in fiction... so I look back and I see that I consciously vacated the contested ground.

The rain began again. It fell heavily, easily, with no meaning or intention but the fulfilment of its own nature, which was to fall and fall.

I think some people wished I'd kept myself out of the book. But I kind of insist on it because I want the reader to share my engagement with the material, if you like, not pretend that I'm doing it completely intellectually.

Now, I - for several years while I was researching this book, I felt quite obsessed by thoughts about sentencing, punishment, how judges arrive at their decisions.
