6. Make influential friends

Documentary evidence shows that when Harry Houdini first arrived in the UK, he struck up a friendship, of sorts, with a man who would go on to pioneer British espionage. A man who would go on to be the inspiration for the character “M” in Ian Fleming’s James Bond.

It begs the question: Beyond the handcuffs and the stage, did the world's most famous mystifier, Houdini, lead a double life as an international informant?

Derren Brown investigates the shadowy network of high-profile connections that shaped Houdini’s global career.

From suspicious passport alterations to intelligence reports signed "HH" ahead of tours through volatile Russia and Germany, the pieces of a tantalising puzzle begin to fall into place.

There is, after all, a striking overlap between the misdirection of a master magician and the tradecraft of espionage. Whatever the answer, Houdini’s fame clearly benefitted from his high-profile connections.
