"Milo and I have been looking forward to this half-term for what feels like forever. We're finally going to the National Space Centre, to meet a real-life space engineer! My whole family wanted to tag along and visit a festival first, where this super-famous, mega-expensive diamond is on display. But guess what? The diamond has been stolen! And the police think my Granny did it so she's in serious trouble. Someone needs to prove Granny Jas is innocent, so it looks like Milo and I might need to go undercover. It's lucky I'm Anisha, Accidental Detective!"--Publisher's description.
