"It is 3999." (For no apparent reason; there's no pre-millennial stuff going on or anything). How many conspiracies can there possibly be beneath the peaceful Intergalactic Olympic Games on Micawber's World? Lots, inevitably, particularly since both the Foamasi and the Wirrrn are involved.
Conspiracy, double-cross, a pair of "lost companions" (as I'm sure Virgin would have titled them) and a minor love-interest for Sam; what more could you want in the far-flung future of the Terran Hegemony? Good and pacy; this one might even make a plausible (8 episode?) TV story.
