If you like being made to think about your Doctor Who viewing, the chances are you'll be more than aware of the Black Archive series.

Launched by Obverse Books in March 2016, the Black Archive sees writers tackle a Doctor Who story, analyse and dissect it, and give their own take on it.

We speak with Stuart Douglas, the range publisher, about how it came to be, and their latest book, which examines A Christmas Carol. He also explains about their charity release, The Six Doctors.
