Follows a boy as his family circumstances change and deals with friendships and enemies at home and school
Georges (the s is silent) has a lot going on. He's having trouble with some boys at school, his dad lost his job and so his mum has started working all the time – and they had to sell their house and move into an apartment.
But moving into the apartment block does bring one good thing – Safer, an unusual boy who lives on the top floor. He runs a spy club, and is determined to teach Georges everything he knows.
Their current case is to spy on the mysterious Mr X in the apartment above Georges's. But as Georges and Safer go deeper into their Mr X plan, the line between games, lies, and reality begin to blur.
