Sommerton High is in lockdown! A fiendish prankster is on the loose! Someone has planted a fake bomb in the playground and the whole school is freaking out! Of course it doesn't take the police long to realise it's a fake. But two days later a series of petty thefts rocks the neighbourhood. Who's behind it all? And why target Sommerton High? Meet the Forensic Amateur Research Team - or F.A.R.T. for short. This crack squad is made up of Sam Tran: unofficial team leader, Madison 'Maddie' Litchfield: tech whiz, Arlia Humphreys: new kid at school (possibly a spy), and Declan Peterson: science guru (prone to accidents). Oh, and Dan Tran, Sam's little brother, who regularly brings everyone lunch. Using their intuition, wits and some surprising knowledge of physics and chemistry, this unlikely mob of misfits sets about finding the prankster thieves!
