While I was writing the book, one of my children was diagnosed with dyslexia. Dyslexia is a very tiny word for a wide-ranging neurological condition that affects different people in different ways. But I was reading an awful lot about it, to try and find ways of helping my child. I think a lot of fiction comes from this desire to confront unanswerable questions, and it's heartbreaking to see your child, a bright child, struggling so much with something that others are finding so easy. It's such an assault to the child's self-esteem and, as a mother, it's hard to watch.

The key thing in my becoming a writer was going on a Arvon Foundation residential writing course. I took with me a really messy twenty thousand words of something that later became After You'd Gone, my first novel. My tutors were Barbara Trapido and Elspeth Barker.

In the first night of the Arvon Foundation course, Elspeth Barker said something about the newspaper along the lines of - and I'm paraphrasing - "I do these pieces for them and it's amazing, because I don't type it out, I just fax it as it is, and the literary editor has a machine that can transform my handwriting into typed text." At which point I put my hand up and said, "Actually, I'm that machine."

Gretta sits herself down at the table. Robert has arranged everything she needs: a plate, a knife, a bowl with a spoon, a pat of butter, a jar of jam. It is in such small acts of kindness that people know they are loved.

I have no control, of course, over how I'm marketed. It's a sad thing, though, that so many people perceive literature to be gendered. The idea that some subjects are male and some are female is just preposterous to me. It's reductive and nonsensical, to separate writers and subjects and plots along gender lines. It's meaningless.

I think it's dangerous to have lots of time on your hands as a writer. Time to pursue every little alleyway, to follow every single whim. I feel I've done my best writing when I'm stretched for time, when you're most pressured.

We're much better at dealing with dyslexia today than in 50th, but reading difficulties are still a problem in the U.K. I believe there's currently something like eleven thousand functionally illiterate adults in the U.K.
