Only very loosely related, but here goes:
In the mid-1970s, there was a CBS Radio Mystery Theatre (it takes fantastic writing and even better [voice-]acting to tell a mystery story on radio, but they did it every weeknight) about a single male business executive, his single female secretary who had a MAJOR crush on him, and his fiancee with a drinking problem trying to sober up before the wedding so that they could live happily ever after.
One day, the executive came home, and the fiancee had hung herself.
The cops investigated if there had been a break-in, if the fiancee maybe had money problems from her drinking, if the executive had threatened to break the engagement. But one particularly perceptive detective noticed the secretary's intense crush, and cracked the case.
Earlier in the day, the tipsy fiancee had called into work, desperately missing the executive. The secretary refused to put him thru, lying and saying he was busy in a meeting. She then hung up, saying "Please, please don't hang yourself by your bathrobe belt."
Well, the subliminal suggestion had done the trick. That's exactly what the fiancee had proceeded to do. The detective told the secretary she couldn't go to jail on such flimsy evidence, but he warned her that if she ever "made a move" on the executive and attempted to marry him, he would tell the executive what had happened.
Very sexy. But would have been even sexier (and less deadly) if the fiancee and secretary had just fought over him.
