THE SECRET HOURS

A nothingburger investigation of the security practices of British intelligence turns red-hot in this stand-alone from the chronicler of Slough House.

The Monochrome panel, convened by an adviser to the prime minister with a special grudge against the British intelligence service to gather evidence whether (read: that) the pencil pushers at Regent’s Park have exceeded their authority, calls witnesses from an interminable list, questions them at tedious length, and then, once it establishes that their testimony is unsuitable or meaningless, destroys its notes on them because they’ll never make it into Monochrome’s final report. Civil servant Griselda Fleet has agreed to serve as the panel’s first chair only because her precarious financial situation means that she can't afford to get canned. Ambitious flack Malcolm Kyle, the second chair, has resigned himself to the fact that his advancement is on hold as long as he’s serving the Crown this way. Then several things jolt everyone to attention. Someone tries to kidnap and kill Max Janacek, a retired academic who has a history with MI5. Someone plants a folder filled with highly classified information on Kyle. And when the worthies of Monochrome decide to pursue the information in that folder—information that never should have come their way—they turn up a witness with jaw-dropping news to impart about an operation that Station House ran in Berlin years ago. Readers who’ve joined Herron in following the Slow Horses in a series of rollicking, scary novels won’t be surprised to learn that everyone here looks down their noses at everyone else, that everyone has a price, and that conflicts within MI5 are much more likely to turn lethal than conflicts outside, against England’s nominal enemies.

As usual, there’s a lot here to swallow. Fans will rejoice to see MI5 survive despite its members’ best efforts.
