When an art teacher put a modest advertisement in Private Eye as a painter of 'genuine fakes', he had no idea that it would lead him to becoming a willing part of the biggest art fraud in Britain. Among one of the few people who responded was the mysterious and magnetic John Drewe, apparently a Professor and an inventor with impressive connections and a vast art collection. But really Drewe was a conman who was soon to take in the British art world with a daring scam that would last a decade. He sold galleries and collectors some 200 'genuine fakes' made with B&Q emulsion paint, mixed with KY jelly.
