Publisher's Synopsis
An asteroid in the furthest reaches of space - the most secure prison for the most dangerous of criminals. The Governor is responsible for the cruellest murderers. So he's not impressed by the arrival of the man they're calling the most dangerous criminal in the quadrant. Or, as he prefers to be known, the Doctor. But when the new prisoner immediately sets about trying to escape, and keeps trying, the Governor sets out to find out why.
