Former SAS trooper turned undercover cop Dan Spider Shepherd knows there are no easy solutions in the war against terrorism. But when a killer starts to target pardoned IRA terrorists, Shepherd has to put his life on the line to protect his former enemies; and as a Muslim assassin closes in on his prey, Shepherd realises that the only way to save lives is to become a killer himself.
Dan 'Spider' Shepherd is infiltrating a tightly-knit team of bank robbers, when a group of home-grown Islamic fundamentalist fanatics embark on a campaign of terror the like of which Britain has never seen. Car bombs and beheadings are only the prelude of what they have planned.
And Shepherd is the only man who can stop them.
Villains across London are being beaten, crippled and killed by vigilante cops. Crime rates are falling, but the powers that be want Dan 'Spider' Shepherd to bring the wave of rough justice to an end. Shepherd has always known that there are grey areas in the fight against crime, and that sometimes justice gets lost in the process. But when his own family is brought into the firing line, Shepherd has some hard decisions of his own to make.
