Ben Aaronovitch began his career in screenwriting, writing for TV juggernauts such as Casualty and Doctor Who. His novels are cut from similar cloth, with his bestselling Rivers of London series following the adventures of Peter Grant, a young police officer who winds up working for The Folly, a secret branch of the Met that handles the supernatural.

He spoke to Sian about the eighth book in the series, False Value, the vital role London plays in his fiction and what it is like adapting the books with Simon Pegg and Nick Frost.

And we chat about the arrival of Hilary Mantel’s much anticipated The Mirror & The Light, the third book in her trilogy about the life - and death - of Thomas Cromwell.
