Slough House

Slow Horses

River Cartwright’s career ends in a training exercise in a packed King’s Cross, and he is posted to Slough House, the address where the Service keeps the officers it cannot dismiss. Then a teenage boy is filmed on his knees with a beheading promised, and the Park takes the case while telling the slow horses to stay out of it. Their first operation is a lesson in how the Service spends its own — and in what Jackson Lamb chooses to know and not say.
