The Mists of Time features the Third Doctor and his companion, Jo Grant. When Jo finds herself on a distant planet in the far future, she's greeted by an archeologist, Calder, who is marooned on the deserted world. With no memory of how she arrived, Calder reminds her that they've met before—and she starts to recall a tale of ghosts and murders and a terrible Time Lord secret... This was an exclusive audio download offered to readers of Doctor Who Magazine issue 411, and is also available in the box set The Companion Chronicles: The Specials.
