There were a number of reasons for switching to Goldmann, but a deeply personal one for me was the way Heyne (in Sourcery, I think, although it may have been in other books) inserted a soup advert in the text a few black lines and then something like Around about now our heroes must be pretty hungry and what better than a nourishing bowl etc, etc. My editor was pretty sick about it, but the company wouldnt promise not to do it again, so that made it very easy to leave them. They did it to Iain Banks, too, and apparently at a con he tore out the offending page and ate it. Without croutons.
