[1] Marshall McKann, a businessman in the coal industry, is badgered by his wife into attending a concert at Carnegie Music Hall in the Oakland neighborhood of Pittsburgh, Pennsylvania, with her and her visiting friend Mrs. Post.
Later that night on his way to a train to New York City, he accepts a request to drive the singer to the station, as her car has stopped working.
She only finds out it is him when they get to the railway station in East Liberty, as she couldn't see his face properly before that.
The next day he realises she has dropped one of her golden slippers, and decides to tuck it into his suitcase.
At his hotel he bins it, but the cleaning-lady puts it back in his closet, thinking it must have been a mistake.
