Patient Zero was the one hundred and twenty-fourth story in Big Finish's monthly range. It was written by Nicholas Briggs and featured Colin Baker as the Sixth Doctor and India Fisher as Charlotte Pollard.
This story also concluded the story arc regarding the viruses from the Amethyst Viral Containment Station, which began with AUDIO: Urgent Calls. However, the consequences of this story carry into AUDIO: To the Death.
To discover the answers, the Doctor must travel back in time, beyond all known civilisations to the vast, mysterious Amethyst Viral Containment Station. But answers lie within the TARDIS too. Someone who has been there a long, long time...
Meanwhile, the Daleks have travelled back in time on their own mission, to bring them the ultimate victory they crave. But it is a mission so complex and delicate that even they know they must beware the web of time...
Who is Patient Zero? What has happened to Charley? And why have the legendary Viyrans been summoned?
