I've sent you the details privately, Irene, but for all those other curious people... it was "H is for Hubris" -- in an early draft, HG Wells didn't show up until halfway through the story. Irene said something about it being a big surprise, and I started to think that I didn't want it to be such a shock at that point... I don't like to lead readers on to expect one kind of story, and then jerk them around to something completely different halfway through. (Hmm, that probably explains why I don't like non-obvious Tank Endings
)
So I had to go back and write three or four earlier scenes with Wells, tucked in among my existing scenes. That gave the story a different feel, which I think worked much better. Thanks, Irene!
Moral of the story (if there is one) is that just getting audience reactions can be extremely valuable; grammar corrections are not required.
