I don’t have a garden shed, or a cubby hole, a desk or a favourite chair. If I could find a place to swing it, I'd probably have a hammock with a 'Hazardous Area: Author at Work' sign attached. I hate sitting in chairs, to tell the truth – I've had rheumatoid arthritis since my twenties, and my knees really dislike prolonged periods of sitting down. I do have an office, but I can't write in it. It's for filing and business paperwork and going cross-eyed over accounts and spreadsheets. So my writing space – wherever I happen to be, home or abroad – is my bed or the sofa. Legs stretched out, laptop switched on, and (when I am at home in the country) a cat or two curled up beside keeping an eye on things while ensuring I am still fully functioning as their personal central heating system.
