The renegades: a Peter Ashton novel
(Book)

When an British secret service operative turns up dead in a London restaurant shoot-out, the SIS suspects that he was caught in the crossfire of a robbery with overtones of underworld drug gangs, and that his death was coincidental. But it soon turns out that one of the corpses was a shadowy figure with multiple identities and potential ties to terror organizations. Evidence of a cover-up emerges from somewhere deep within the British secret services, and it becomes clear to Peter Ashton and the SIS that something far more nefarious than a random shooting has taken place. Even more alarmingly, when suicide bombers attack British Council offices in Pakistan and Russia, it becomes obvious that a terrorist operation is underway. Now it's up to Ashton and his colleagues to follow the faint traces, uncover and disrupt the operation, and track down the two central figures at the heart of the conspiracy.
