Banksy: The Man Behind the Wall, By Will Ellsworth-Jones

It's a joy to read but you won't learn many details about the artist known as Banksy – aside from him being tall, bespectacled, and bearded (sometimes).

His name was revealed by the Mail on Sunday in 2008 though Ellsworth-Jones does not repeat it due to a promise made to interviewees.

Instead he pursues a more interesting course – the impact of Big Bucks on Banksy.

Despite the efforts of this spray-can Pimpernel to have his cake and his street-cred, Ellsworth-Jones damningly concludes, "He is much richer than I imagined and much, much more controlling."
