My heartfelt thanks go to Mike Rapps, solicitor, author and friend, who answered all my legal questions in great detail and with enormous patience. Also to the Cornish Andersons, Rosie and Ian, who offered me bed and board and drove me round Cornwall while I was doing my research.
Finally to my long-suffering agent, Judith, and editor, Rosie. Thank you both for your continued encouragement, your input and your patience, without which I might well have sunk beneath the wave.
