In Slough House, the London outpost for disgraced spies of MI5, memories are stirring, all of them bad. Catherine Standish is buying booze again, Louisa Guy is raking over the ashes of lost love, and new recruit Lech Wicinski, whose sins make him outcast even among the slow horses, is determined to discover who destroyed his career, even if he tears his life apart in the process. Meanwhile, in Regent's Park, Diana Taverner's tenure as First Desk is running into difficulties. If she's going to make the Service fit for purpose, she might have to make deals with a familiar old devil....

A breakneck race against time…and an implacable enemy. An anonymous young woman murdered in a run-down hotel, all identifying characteristics dissolved by acid. A father publicly beheaded in the blistering heat of a Saudi Arabian public square. A notorious Syrian biotech expert found eyeless in a Damascus junkyard. Smoldering human remains on a remote mountainside in Afghanistan. A flawless plot to commit an appalling crime against humanity. One path links them all, and only one man can make the journey. Pilgrim.
