This book follows a similar formula to The Afghan, by the same author. There’s a terrorist threat to the western world- extremists brainwashed by a radical cleric are murdering prominent public figures. A former US marine (codenamed The Tracker) must track down the preacher (codenamed The Preacher) who only posts online – and eliminate him. The Tracker recruits a young, supremely talented hacker to help locate the source of the inflammatory material – he is codenamed Ariel (disappointingly, not The Hacker!)
The constraints put in place by politicians make The Tracker’s job harder – even having located The Preacher, he cannot order a drone strike because it is a built up area. So begins an elaborate plot to bring The Preacher out of his ‘fortress’ into a remote area, where he can be attacked. First, he is discredited in the eyes of his followers, by hacking his website and posting a fake message recanting his previous statements. Second, he is informed by a trusted friend (actually Ariel, aka The Hacker) that a local warlord has kidnapped a westerner and is prepared to sell – executing the man would re-instate his fearsome reputation. Having set the bait, the tracker must recruit a lethal army unit to seek and destroy The Preacher at his meeting with the warlord.
