I've been working sooo hard with Milo and Govi to make our super-erupting volcano for the school science fair. I really thought we might win first prize - a trip to the National Space Centre. But now we're in BIG trouble. One minute we were in the lab practising our science demo, and the next thing we knew, our volcano exploded and flooded the corridors. School had to be cancelled! But did we really get our project so wrong - or is someone else trying to win first prize? Looks like a case for Anisha, Accidental Detective!
