Perry Mason S01 E38 The Case of the Terrified Typist

"Almost anyone is capable of a crime under certain circumstances."

While a woman is searching the office of the South African Diamond Company, George Baxter enters to meet Walter Lumis and Duane Jefferson. He notices things in disarray and questions the woman. She makes an escape, enters Perry Mason's office, and pretends to be a typist sent by a temp agency.
