When literary editor Charles Monteith first saw William Golding's manuscript of Lord of The Flies it was a good deal longer and less focused. He pruned it and reshaped it together with the author and the book launched Golding's career. Kate Figes talks to Monteith and to Liz Calder, one of the new generation of editors, as well as to authors themselves, about that vital link between them and their work and how it is changing in the modern publishing world.
