Bombs are exploding in the streets of London, but life seems to have planted more subtle booby-traps for Miles Flint. Miles is a spy. His job is to watch, listen and report back to his superiors. Nothing more. Miles doesn't lust after promotion, and he doesn't want action. He wants, just for once, not to botch a case. Having lost one suspect, with horrific consequences, Miles becomes too involved with another. His marriage is crumbling and he's being pursued by "The Hel-Raiser of Fleet Street".

Then Miles is given one last chance for redemption - a trip to Belfast, which quickly becomes a flight of terror, murder and shocking discoveries. But can the voyeur survive in a world of violent action?
