Riz Chester has a passion for forensic science. One day at school there is a commotion outside the music room and something is missing. Riz recruits her friends, Jenny, Sabrina, Lachie A and Lochie C and breaks out her fingerprint tools. Is it more than a misunderstanding? How can they work out what happened when no one will even tell them what is missing? And is the mark left behind in the music room really a fingerprint?
Join the five friends as they recruit some extras to take fingerprints from everyone who might have gone into the music room and find a potential suspect.
