Chance of a Ghost is a 1958 Australian television play directed by Royston Morley and written by James Carhartt based on a play by Carhartt and Nicholas Winter.
She becomes so obsessed she is "possessed" by the spirit of the dead woman and begins to look and behave like her.
The idea for the plot came from a murder committed at the Medical Arts Building in New York.
"For years afterwards no one would rent the place and it became known as the haunted penthouse," said James Carhartt who turned it into a play with Nicholas Winter.
Carhartt was an American who moved to Sydney and he adapted the play for Australian television.
