The S.M.A.R.T.S. can’t wait for the local school’s Art of Science exhibition, which will feature pupil’s artwork made through scientific methods. It’s sure to be a great show, except for one problem – the centrepiece necklace has vanished! The S.M.A.R.T.S are baffled. There’s no sign of a break-in, and the door to the gallery was locked. Could the jewellery really just disappear? It’s up to the S.M.A.R.T.S. to solve the impossible crime. Using a combination of engineering, robotics and some serious brainpower, Zoe, Caleb and Jaden investigate every clue. Will they find the necklace in time for the exhibition’s opening night, or will they be blamed for the school heist?
