When he refuses, he sees his world collapse and finds himself accused of a high-profile murder he did not commit. Yet the evidence against him is overwhelming.
Only his former comrade-in-arms believes his innocence. The SAS tracker finds himself on the trail of the most deadly adversary of all. A rogue element within the secret state.
