Julie Mason is an estate agent asked by Jimmy King to come and inspect the King's River development. She first appears at the Woolpack having her lunch and discusses the houses with Jack Sugden and Zak Dingle. When she mentions that the potential purchasers will be a certain standard, Jack takes offence. Later at the development site, Jack tries to get a tractor to work, but to no avail. Jimmy tries to get it to work, but accidentally pulls a lever that causes Julie to get caked in mud. Furious, she storms off.
Julie returns after Jimmy had paid for her suit. She tells Jimmy that she is impressed and would even move there herself. She runs into Shadrach Dingle who tells her that his door is open anytime, unnerving her.
