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 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.
