'For over a decade I worked as a secret agent in a clandestine army unit, tracking down terrorists and facilitating their arrest, capture or death. This is my story.'

James E. Mack has been in many tight spots in his life, ever since joining the JSG, a shadowy British army unit that recruits and runs spies. He cut his teeth in Northern Ireland but he came closest to death in Iraq. Seconded to Task Force Black, the special forces operation searching for high-value Al Qaeda targets, James risked his life to operate under-cover on Baghdad's streets by day and on capture-or-kill missions at night. Taken by militia, he narrowly escaped with his life and later outwitted a double-agent who wanted to capture him.

In Afghanistan he hunted down the Taliban, from senior commanders to kidnap and assassination squads and narco-traffickers. Going undercover to stop a shipment of IED components took him deep into Taliban territory, with no possibility of rescue if anything went wrong. As tense and gripping as a thriller, Hunter Killer Spy takes us into a secret and dangerous world and reveals the lengths agents like James will go to as they race to stop some of the world's most deadly terrorists.
