Let me take you back to the Britain of 1951. The Second World War had ended just six years earlier. London, like many other British cities, had been bombed relentlessly and still bore the scars of the Blitz. Surviving buildings were covered in layers of dark sooty dust and rationing was still the order of the day and, for fresh meat, remained in place until 1954.

The main attraction in Vauxhall is a building you cannot enter. Vauxhall Cross is the headquarters of the Special Intelligence Services (formerly MI6) and the employer of Britain’s most famous fictional secret agent, James Bond, often referred to simply by the number 007. The double 00 prefix indicates that Bond has a ‘licence to kill’, an invention of his creator Ian Fleming who worked for Naval Intelligence during the Second World War when the double 0 symbol indicated that a document was classified as ‘top secret.’
