I have to say this was a rather disappointing Fourth Doctor / Leela audio. The start was rather promising, with a last survivor of his race attended by a robot nurse, discovered simultaneously by the Tardis crew and a surveying spaceship; but it wasn't terribly well joined-up together, and while Baker clearly loves doing his lines he's had better. It had some signs of just being written in a rush - for instance, why does Kellaway not ask where Sutton is when the Doctor turns up without her at the end? And I'm sorry, but "Colophon" is a silly name for a sinister alien race. Most of this series of Fourth Doctor adventures has been better, and so is most of Morris's work.
