"During the day I was writing in cafés as everyone famously knows, but could I just say for the record once and for all 'cause it's really irritating me: I did not write in cafés to escape my unheated flat, because I am not stupid enough to rent an unheated flat in Edinburgh in midwinter. It had heating. I went out and wrote in café because the way to make Jessica fall asleep was to keep her moving -- in the pushchair. So I used to take her out, tie her out, put her in the pushchair, walk her along -- the moment she fall asleep, into the nearest café and write."
