Thomas High School principal has been viciously assaulted and when his stepson says he was offered a black market VCE exam paper, the Heelers suspect exam theft may have been a motive for the attack-that is until they start probing into the principal s dysfunctional family. Meanwhile, Senior Constable Ben Stewart has never made any secret of his desire to be promoted to sergeant. But to his immense frustration, every time it appears he s about to nab the position, it gets snatched from right under his nose. Now it seems as though poor Ben will miss again because of his old nemesis, Inspector Russell "Rusty" Falcon-Price.
