|Actress India Fisher, who voices Charley.|
"Scripts underway for Charlotte Pollard audio series. Hopefully recording in October. Very excited."Charlotte, or Charley as she is known to most listeners, was last seen in Doctor Who: Blue Forgotten Planet, where she left the Doctor and walked into the sunset hand-in-hand with the mysterious Viyrans.
The concept for the series is currently unknown to anyone but the folks at Big Finish, but it would be unlikely given that Nick Briggs is so involved in the series, that his creations, the Viyrans would not be around somewhere.
