We are thrilled Mick Herron is joining us to talk about his latest spy thriller Slough House on publication day! Ann Cleeves will be chief interrogator for the evening too.

'Kill us? They've never needed to kill us,' said Lamb. 'I mean, look at us. What would be the point?'

Slough House has been wiped from Service records, and fatal accidents keep happening. No wonder Jackson Lamb's crew are feeling paranoid. But have they actually been targeted? With a new populist movement taking a grip on London's streets, and the old order ensuring that everything's for sale to the highest bidder, the world's an uncomfortable place for those deemed surplus to requirements.

The wise move would be to find a safe place and wait for the troubles to pass ... but the slow horses aren't famed for making wise decisions.
