Checkmate (S11E27)
The intense investigation into the attacks on the Mt. Thomas police presses on as Tom travels to Melbourne to track down the source of the bomb parts. His investigation leads him to suspect chemical dealer 'Doc' Parkinson, and he's determined to prove that he supplied the Baxters with materials for both the bomb and the speed. Despite Nick's reservations, he joins PJ and Amy—who impress everyone at the station—on a new search of the Baxter property, where he discreetly plants listening devices that eventually help them uncover the truth. Meanwhile, Jonesy and Susie find a stunning woman named Donna trapped in a rubbish skip, and Jonesy quickly develops a crush on her. Later that evening at the pub, Donna's ex confronts Jonesy, claiming she’s a con artist who took everything from him. Ben has been excessively showering Susie with lavish gifts, but she returns them, leaving him feeling confused and uncertain.
