A key member of a Downing Street think-tank has disappeared without a trace. Claude Whelan, one-time First Desk of MI5's Regent's Park, is tasked with tracking her down. But the trail leads straight back to Regent's Park HQ itself, with its chief, Diana Taverner, as prime suspect. Meanwhile her Russian counterpart has unexpectedly shown up in London but has slipped under MI5's radar. Over at Slough House, the home for demoted and embittered spies, the slow horses are doing what they do best: adding a little bit of chaos to an already unstable situation. In a world where lying, cheating and backstabbing is the norm, bad actors are bending the rules for their own gain. If the slow horses want to change the script, they'll need to get their own act together before the final curtain. *Includes the short story Standing by the Wall: A Slough House Interlude* 'The foremost living spy novelist in the English language' New Statesman 'This is entertainment of the highest class' Literary Review 'The man is a genius' The Spectator
