When Transit was published, how many Doctor Who fans would have imagined that its writer would go on to become a British bestseller?

We're delighted to be joined by Ben Aaronovitch, to discuss his first original novel, the tenth New Adventure to be released - Transit.

He's since gone on to write the Rivers of London series, which follows the escapades of Peter Grant (not to be confused with the former Celtic and Scotland footballer of the same name).

Ben joins us to talk about Transit, and his latest Rivers of London book, Stone & Sky.
