Henry Falworth goes to the Central Cinema every Saturday, paid for from his paper-round earnings. This Saturday, in 1954, he sees ‘The Black Shield of Falworth’ starring Tony Curtis as Myles. He’s so excited: how could there be a big Technicolor film with his name in the title? He leaves the cinema, as usual, in a state of euphoria. What is different is that though he knows he isn’t Myles, as he’s only eight years old, he, like Myles, has to stop the baddies.
