From The Perry Mason TV Show Book (Revised)
Della and Perry make an attempt at dinner in a romantic French restaurant only to be interrupted by business as usual. Perry gets a phone call and an envelope containing $500 from a mysterious woman. She wants him to make an exchange for her: the money for some documents.

It’s amazing enough that a lawyer would put himself on the line for a woman he’s never met; but it’s incredible that he’s still willing to represent her after the drop-off point turns out to be the scene of a murder.

The mystery woman, Marian Fargo, is played by a young and dark-haired Angie Dickinson. Charles Gallagher is played by Paul Picerni—fifties “jock” and war-movie hero.
