Description
The Secret Hours by Mick Herron is a standalone spy thriller set within the Slough House universe. It begins when retired academic Max Janáček discovers he’s being hunted and shifts to the Monochrome inquiry—an ineffective MI5 investigation into past intelligence misdeeds. A mysterious OTIS file leads to flashbacks in 1994 Berlin and ties to characters like Alison North. Herron weaves bureaucracy, dark humour, espionage and moral ambiguity in a gripping, layered story.
