Synopsis by Hal Erickson
Seven-year-old Peggy Smith (Laurie Perreau) has spent most of her life at the exclusive Westcroft Boarding School. Her tuition has been paid by an unknown person, who has also sent Peggy a doll each year. Curious about her benefactor, and wishing to find out who her parents were, little Peggy consults attorney Perry Mason (Raymond Burr). It turns out that Peggy is the granddaughter of wealthy recluse Courtney Jeffers (Francis X. Bushman), whose hard heart melts the moment he sets eyes on the child. But no sooner has Jeffers acknowledged that Peggy is his granddaughter than he is bludgeoned to death--and the person accused of the crime is Linda Osborne (played by Maggie Mahoney, real-life mother of actress Sally Field), who at Peggy's request is defended by Perry during the inevitable courtroom intrigues.
