Well, the biggest question mark here is what happened to the REAL double agent with the diamonds? (Rose Temple or something like that). Neither the police nor the criminals knew what she looked like; she never seemed to show up. Maybe she was hit by a bus or something? Crime drama; no supernatural elements.

A neglected wife looks into a mirror and sees her reflection change depending on her feeling of self worth . She leaves her home and works her way into some interesting and suspenseful situations. Soon, she learns that her boring, staid, life wasn't quite so bad.

A woman whose politician husband has little time for her feels like she is disappearing and her reflection in the mirror is growing less distinct. She ends up leaving for a holiday retreat and is approached by several people who believe her to be involved in some kind of criminal investigation/conspiracy. She discovers with the attention that her reflection is reappearing in the mirror and indulges herself in the attention, but it’s a dangerous game.

The wife of an important politician feels increasingly irrelevant as her husband cancels engagements with her in order to further his own career. What's more, she feels insubstantial and invisible, as she slowly loses her reflection.
