  Summary

  An MI5 agent vanishes without a trace on foreign soil. A controversial private intelligence agency appears to hold pieces of the puzzle. Slough House -the place where spies go to fade into obscurity- is tasked with putting it all together.

  Forced into an unusual alliance, MI5 leans on Elise Clermont, the outsider with secrets of her own. Tasked with uncovering the truth, she’s thrown into the chaos with the rest of the slow horses. The deeper they dig, the harder it is to know who to trust. And questions seem to multiply as the road towards truth stretches out before them.
