Of course, philosophers have debated for years about where Great A’Tuin might be going, and have often said how worried they are that they might never find out.
They’re due to find out in about two months. And then they’re really going to worry …

Tumbling past, totally out of control, is the bronze shell of the Potent Voyager, a sort of neolithic spaceship built and pushed over the edge by the astronomer-priests of Krull, which is conveniently situated on the very rim of the world and proves, whatever people say, that there is such a thing as a free launch.
