Max-Catt is now firmly embedded within the SAS, trusted to lead men on the most dangerous covert operations. When he is chosen to take a small team deep behind enemy lines on a high-risk sabotage mission, the stakes could not be higher.

As the operation unfolds, Max discovers there is a traitorous double agent working within MI6. With time running out, he must identify the mole before the betrayal reaches him first. At the same time, a hit-team has already been tasked with terminating the meddling SAS officer. As Max digs deeper, he uncovers a disturbing chain of murders in the UK, seemingly connected to his mission — but the links refuse to fall neatly into place.

Hunted from multiple directions and unsure who he can trust, Max is forced to keep moving while piecing together the truth. With enemies closing in and no safe way out, he must act before the conspiracy consumes him. There is no turning back.
