Winter (audio story)

 was a 2007 Big Finish Productions full-cast audio short story, featuring the Fifth Doctor and Nyssa. It was set within the last few moments of the fifth Doctor's life, as he was battling the Master for control of his regeneration — meaning that most, but not all, of the narrative takes place in the Doctor's mind.

It was further notable for being the only Big Finish audio, as of 2011, to use the character of Kamelion in any significant way.
