Emancipation of Daleks- a story that is much more in line with 1984 than Doctor Who. It's by far the most mature Big Finish story I've heard in such a long time. And it's a shame it's not a full cast audio drama with Pearl Mackie and Peter Capaldi. But this audio book is able to play into its niche audience and provide a really adult Doctor Who story. And I applaud it for that.
