Mick Herron has won the Theakston Old Peculier crime novel of the year award, after his fifth time being shortlisted in six years.
Herron won the award for Slough House, the seventh instalment in his series of the same name, which follows a band of failed spies. In the book, a new populist movement is taking hold on London’s streets, and the spies find themselves on the run in the aftermath of a blunder by the Russian secret service that left a British citizen dead.
