'A first-rate modern thriller' Daily Mail

Set in the same fictional London as the CWA Dagger Award-winning Slough House series, Nobody Walks introduces JK Coe, a fledgling spy who's about to get a harsh lesson in the realities of life on Spook Street.

Tom Bettany is working at a meat processing plant in France when he gets a voicemail telling him that his estranged 26-year-old son is dead - Liam Bettany fell from his London balcony, where he was smoking pot.

Now for the first time since he cut all ties years ago, Bettany returns home to London to find out the truth about his son's death. But more than a few people are interested to hear Bettany is back in town, from incarcerated mob bosses to those in the highest echelons of MI5. And some of them - like JK Coe - will have cause to regret his reappearance.

Bettany might have thought he'd left it all behind when he first skipped town, but nobody ever really walks away.
