...is Gnome's "What If Gordon Banks Had Played?", currently coming to a conclusion of its run on Usenet. Alternately horrifying and enthralling, it's the story of Britain's descent into facism and anarchy under a Powell government in the 1970s. Whoever Gnome is, his writing style is superb, and his take on British politics is excellent.
Serialised in soc.history.what-if and collected on his web site, his mix of reports, interviews and book-excerpts is a snapshot of a history we narrowly escaped.
A satisfying reminder that perhaps this is the best of all possible worlds.
