The Secret Hours

It’s not all Aston Martin sports cars and martinis (“shaken, not stirred”) In Herron’s (Slow Horses) spy world. The reality is more mundane and bureaucratic in post-Brexit London, where British intelligence services have been the subject of a two-year inquiry, codenamed Monochrome and launched by a vengeful, now ex-prime minister. Thanks to the best efforts of First Desk, the agencies’ top banana, the panel headed by civil servants Griselda Fleet and Malcolm Kyle has been unable to uncover any wrongdoing. But as the probe is about to be shut down, Malcolm mysteriously receives a classified file exposing a long-buried operation in post-Cold War 1994 Berlin that ended in tragedy. How does this connect to a recent botched attack on a retired “joe” in rural Devon? Herron skillfully ties the loose threads together in a satisfying, yet melancholy conclusion that reflects upon the collateral damage caused by betrayals that are the lifeblood of espionage: “The cost of heroism—of betrayal—was high; it was the same cost, seen from opposite sides. And the same cost applied, it seemed, if you were neither hero nor traitor, but simply occupied the same neighbourhood.” Billed as a standalone, this smartly written, funny, and complex thriller is a good introduction for newbies, but fans of Herron’s “Slough House” books will recognize a few crossover characters.
