The Entropy Composition (audio story)

The Entropy Composition was a 2010 Big Finish full-cast audio short story featuring the Fifth Doctor and Nyssa.

It was notable for being a rare example of a Big Finish audio which had been commissioned as a result of an open invitation for scripts. Writer Rick Briggs won out over about a thousand other submissions.
