Ever wondered why the heads of MI6 are called “M”? Well they aren’t. They are called “C”. It all started with Sir Mansfield Smith-Cumming, who signed his docs with a green “C.” This guy was a true legend—a retired Navy man who became the spymaster extraordinaire, famous for his love of gadgets and high-speed Rolls-Royce drives. His dramatic life included cutting off his own foot after a car crash to save his son. MI6 has always been shrouded in secrecy, with its chiefs staying out of the limelight. But thanks to novels and movies, especially those by Ian Fleming, the real-life adventures of these spies have become legendary.
