The One Doctor was the twenty-seventh story in Big Finish's monthly range. It was written by Gareth Roberts and Clayton Hickman and featured Colin Baker as the Sixth Doctor and Bonnie Langford as Melanie Bush.

This audio was released in December 2001 and was considered Big Finish's "Christmas release". It has a notably comic slant to the story. It is the first of two early Christmas releases in the Main Range, the second being AUDIO: Bang-Bang-a-Boom!. Both stories feature Mel.

This story was also notable for the Doctor Who debut of Matt Lucas, who'd later portray the Twelfth Doctor's companion Nardole.

Publisher's summary[]

When the evil Skelloids launch an attack upon the seventeen worlds of the Generios system, its peace-loving inhabitants face total destruction.

So it's lucky that the Doctor, that famous traveller in time and space, is in the area, and that he, along with his pretty young assistant, Sally-Anne, manages to defeat the deadly creatures and save the day.

But now it looks as though the Doctor's luck has run out.

Who is the mysterious, curly-haired stranger, intent on causing trouble? What role does the feisty redhead Melanie play in his scheme? And what have they to do with the sinister alien cylinder approaching Generios?

One thing is certain: for the Doctor and Sally-Anne, there's deadly danger ahead...
