Neil gives examples of h/c stories:
"There was a Time When..." by Robin F Atkins (Horizon #?),< "In The Wake of Ruin" by Linda Willard (I think) in another Horizon zine,< "Alone and Silent" by Kathryn Cutmore (another Horizon offering),<
I enjoyed those stories hugely, but I never realised they classify as h/c, which shows what an innocent I am :-)
Actually, "In the Wake of Ruin" is my favourite PGP story, if only because it really gets Avon off the hook for killing Blake <veg>.
