The Tyrants of Logic (audio story)

 was the second and final story in The Third Doctor Adventures: Volume Four. It was written by Marc Platt and featured Tim Treloar as the Third Doctor and Katy Manning as Jo Grant.

Publisher's summary
The Doctor and Jo land on Port Anvil — a bleak, abandoned mining colony on the remote planet Burnt Salt. A huge armoured crate has recently arrived in the almost derelict Spacehub. No-one knows who it's for. No-one knows what it contains.

Strange creatures lurk around the outskirts, and a rag-tag population of misfits inhabit what is left of the town: a saloon bar owner, a literal one-man band and a hunter of very unusual prey. If they want to survive the night, they're going to have to work together.

Because the Cybermen want the contents of the crate. And they will stop at nothing to get hold of it.
