Lux Radio 37/12/06 (ep153) These Three (Errol Flynn, Mary Astor)

Plot
Following graduation, college friends Karen Wright and Martha Dobie transform Karen's Massachusetts farm into a boarding school. Although new to the area, they are able to find pupils with the assistance of the wealthy Amelia Tilford, who enrolls her malevolent granddaughter Mary and encourages other families to enroll their daughters. Shortly before the school opens, Martha's aunt, Lily Mortar, arrives and forces her way into a teaching position as a way to continue sponging off Martha.

Karen and local doctor Joe Cardin begin to date, unaware that Martha is in love with him. One evening, Joe falls asleep in a chair in Martha's room while waiting for Karen to return to the school. He wakes with a start and breaks a glass, which wakes up Mary Tilford. Before he leaves, he casually refers to his and Karen's plans to marry, and Mary watches from the shadows as Martha sobs quietly once she thinks she is alone.
