In the episode, "Cat and Mouse", Olivia Novak (Cynthia Dale) and Carrie Barr (Sonja Smits), are lawyers. Carrie is a criminal lawyer, and Olivia is an entertainment lawyer. They decide it would be a good idea, to compete each other, by trading cases. Since both are unfamiliar with each other's law pracitces, they each find challenges in solving their cases.
Olivia's new client, named Arnold, is an individual who steals personal belongings, by climbing apartment buildings and breaking through their windows to access these items. He is unfortunatley caught, and Olivia tries to get him ten months in jail, but he refuses. This is because he has a blind sister who he needs to care for and support financially. His method of obtaining money, was through stealing.
Anyway, enough of that synopsis... The actor who plays Arnold, is named Ian Tracey. Look him up on google images and see if he looks familiar.
