Mickey and Mark Moore are Ordinary Decent Criminals -- hard men who live by their own code and leaders of a gang that has made millions at the point of a gun. But when Dan 'Spider' Shepherd is sent to Thailand to infiltrate the tightly-knit team of bank robbers, he discovers that he has more in common with them then he first thought. And that perhaps being a career criminal isn't the worst thing in the world. As Shepherd and his Serious Organised Crime Agency colleagues plot the downfall of the Moore brothers, a more sinister threat stalks the streets of London. 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.
