Suffice to say, the City managed to wrangle its way out.

Nearly ten years later Salter recounted the story to a Londoner on a hungover stumble around the City of London. The Londoner had lived there all his life but knew nothing of this story. “We should make a documentary about this”, said the Londoner, Anthony Killick.

After scrabbling around for a couple of months trying to make a documentary about London with no decent equipment and next to no film making skills, Lee told the story to the film maker Michael Chanan. It took one lunchtime discussion for Michael to come on board.

Over the next year, Salter got in touch with his old contacts and Secret City was born. Selling out across the UK and screening everywhere from Argentina to New Zealand, Secret City made quite an impression, even winning the London Independent Film Award for Best Documentary Feature.

The other achievement was to seemingly turn Salter into a life-long enemy of the City of London, but that’s another story.
