Californian girl Kirby Allen comes to St. Swithins. Her father is a millionaire and Sir Geoffrey hopes that he will contribute an expensive scintillascope to the hospital. But father must be kept sweet so, although Dick, Andy and Duncan are all smitten by Kirby, they must not molest or antagonize her in any way. Strangely enough, she has no interest in any of them and only has eyes for James Gascoigne, who appears to be scoring with her. (thetvdb.com)
