Former intelligence officer and one-time instructor at the British Army School of Sniping, Phil Mason is struggling to make ends meet as a private investigator when he's contacted by his former MI5 liaison officer.
The overstretched Security Service needs all the help it can get hunting down members of al-Qaeda terror cells in the UK and he needs the cash.
But in the murky intelligence world of smoke and mirrors, nothing is necessarily what it seems. Hampered by inter-departmental rivalry and political back-stabbing, what begins as a routine surveillance operation escalates into a full-blown international crisis.
As Mason and his team get drawn into the dangerous underground networks, lives are put at risk and suddenly it all feels very up-close and personal.
In a desperate race against time to uncover the identity and a major threat posed by the terrorist killers, Mason has to come to terms with the unthinkable: there must be a traitor within Britain's security forces.
As time is running out fast, Mason must hastily re-hone his old counter-sniper skills as he returns to the business he swore he had left behind forever. The killing game.
