Nobody Walks (2015) is a completely independent novel even though its MI5 is the same as the one in Herron’s Slough House series. Jackson Lamb is mentioned.

Like the rest, the audio book is narrated by the excellent Gerard Doyle.

The suspicious death of his son brings an undercover spook Tom Bettany for MI-5’s Special Ops out of retirement with a vengeance.

Maybe it’s the guilt he feels about losing touch with Liam that’s gnawing at him, or maybe he’s actually put his finger on a labyrinthine plot, but either way he’ll get to the bottom of the tragedy, no matter whose feathers he has to ruffle.

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.

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