Twenty-six-year-old Maggie Barnes is someone you would never look at twice. Living alone in a month-to-month sublet in the huge city of London, with no family but an estranged sister, no boyfriend or partner, and not much in the way of friends, Maggie is just the kind of person who could vanish from the face of the earth without anyone taking notice. Or just the kind of person MI5 needs to infiltrate the establishment and thwart an international plot that puts all of Britain at risk. Now one young woman has the chance to be a hero - if she can think quickly enough to stay alive.

Slough House is a dumping ground for British intelligence agents who've screwed up cases in any number of ways - by leaving a secret file on a train or blowing a surveillance. River Cartwright, one such "slow horse", is bitter about his failure and about his tedious assignment transcribing cell phone conversations. When a young man is abducted and his kidnappers threaten to broadcast his beheading live on the Internet, River sees an opportunity to redeem himself.
