Perry Mason (1957)

Season 4: Episode 9

Perry's fishing trip to Scotland is interrupted by seven year old Peggy Smith. Peggy is living at a boarding school and searching for her identity since she has no idea who her real parents are. After searching into the matter, Perry comes to believe that Peggy is the daughter of Clark Lawson and Margaret Jeffers Lawson. Margaret was the daughter of wealthy Courtney Jeffers who disowned her after she eloped with Clark. Both parents died shortly after Peggy was born. Jeffers, a mean and miserable old man, has his heart warmed after meeting Peggy and changes his will to leave everything to her. The next day, he is found dead, killed by a blow from a poker.
