I don't listen/watch/read/etc.
Doctor Who, so I'm not absolutely sure about this.
But, I do believe that there is a new free episode of it just now available from Big Finish:
Doctor Who: The Early Adventures: The Age of Endurance.
To get it, go to
this Big Finish webpage. As the directions state, use code "newseries3" (without the quotation marks).
This episode is only part one, I don't know how many total parts that there are. So, while episode one is
free, if you end up liking what you see, you will probably have to shell out some money to get the rest of the episodes. Of course, tubemonkey probably knows of a way that you can you can them free somewhere or another, knowing him. ha
