what is slow horses about

Slow Horses is about a group of disgraced MI5 agents who have been relegated to a dumping ground office called Slough House, overseen by the cantankerous Jackson Lamb. These "slow horses" are agents who have failed or bungled their tasks badly enough to be sidelined but not fired. They are given tedious, obscure jobs and face verbal abuse, yet they get involved in investigating critical cases, including a kidnapping by a right-wing extremist group. The story follows their attempts to redeem themselves and uncover deeper conspiracies within the MI5 agency. The main plot revolves around River Cartwright, a young agent who was disgraced for a training exercise failure and becomes entangled in the hostage situation and political intrigues within MI5.
