James Peak isn't an art critic, or even a journalist. He's a Banksy super-fan, and in this series he, and his soundman Duncan, get closer than close to Banksy's secret world - telling the story of the graffiti kid who made spraying walls into high art, the household name who is completely anonymous, the cultural phenomenon who bites the hand that feeds him.

James persuades a member of Banksy's secret team – someone who worked closely with the artist when they were starting to cut through – to talk about the experience. The story that results is a rollercoaster ride.

In this episode, Banksy's new show, Crude Oils, stars 200 live rats scuttling about the gallery floor. It certainly brings in the crowds.
