If you have read Iain Sinclair’s books you will know that he is a stylist with a love of language. You will also know that he has opinions to express and projects to promote or destroy: London’s Olympic park was one of his targets. He has lived in Hackney for much of the past 40 years and his previous book of that name was so provocative that Hackney council tried to ban him from giving a reading at a local library.
