FALLOUT (Nick Sullivan series Book 1)

The British Government is being blackmailed by criminals who have got their hands on a quantity of plutonium left over from the cold war. Only one man knows their identity and can prevent a catastrophe but he is on the run for a murder he didn€t commit and has no intention of being found.
As the authorities attempt to hunt him down, the clock is ticking and they are running out of time. They pin their hopes on the fact that a bunch of amateurs won€t have nuclear technology and the worst they€ll come up with is a dirty bomb. With luck, the carnage can be limited. A few people might die in the explosion but the majority will run away at the first sign of danger and the radiation will drift harmlessly into the atmosphere.
But what if the terrorists have found a way of keeping the radiation near to the ground, encouraging people to hang around breathing in death and when they invite them to their own slaughter they come willingly?
They would be dangerous then...wouldn€t they?
