Leslie was also the author of the novels The Scent of the Roses and The Windfall, and wrote various plays for the Pasadena Playhouse.
After becoming secretary of the Association Against the Prohibition Amendment, she began writing a weekly column called "One Girl Chorus" for The Pittsburgh Press.
The column was eventually adapted by Wetstein and Jerome Lawrence as a radio domestic comedy titled A Date with Judy, which she adapted and exploited across all entertainment forms possible at that time, including theatre, film, television, and comic books.
Wetstein moved permanently to Hollywood in the late 1930s,[3] and by 1938, she had talked her way into a job at Columbia Pictures.
Based on her success with A Date with Judy, she built a career writing teen-driven entertainment like Henry Aldrich Gets Glamour and Father Was a Fullback.
