Fatal accidents never happen because of just one mistake. It takes a whole chain of stupids lining up just so to put a full stop at the end of an epitaph.
I was heavily into AD&D in my teens (late 1970s-early 1980s) but fell off the RPG habit in the mid-80s and have never gone back to it; my lifestyle today isn't very compatible with having a regular gaming group (too much travel).
My agent is based in New York. And due to a historic accident, my publishing track is primarily American - I'm sold into the UK almost as a foreign import! So I'm quite out of touch with what's going on in UK publishing.
