When Lucia and her dad come to stay for a week, 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 and - worst of all - she is convinced that Idris' mum is a spy. And that just can't be true . . . can it? But even Idris has to admit there is something a bit unusual about their family trip to the zoo. Were his eyes playing tricks on him, or did someone really drop something into Mum's bag? And why is Budi the orangutan, who is normally so cheerful, suddenly off his food? Maybe it's time for some spying, after all.
