My mum is absolutely definitely 100% NOT a spy...

When Lucia and her dad come to stay for half term, Idris can't believe his bad luck. He had prepared himself to share the TV remote and maybe some of his toys - but he hadn't prepared himself for Lucia.

Lucia LOVES spying. She creeps about, listens through doors, scribbles down anything that might be a clue and - worst of all - she is convinved that Idris' mum is a spy.

And that just can't be true... can it?
