Miss Dent (Phyllis Thaxter) is a former employee of Mr. Blake (Zachary Scott). Shortly after the episode begins, she approaches him to talk...and he runs from her. He then tries to dodge her by going into a bar...and he thinks he's evaded her. Soon, however, it's obvious she's not giving up and when he takes his train home from work, she sits next to him and threatens to shoot him unless he sits still and listen to her! Well, that clearly is one way to guarantee he'll stop avoiding her! It seems that some time ago, Miss Dent had a nervous breakdown after she was fired by Blake. Why she blames him for all this is something you'll have to see for yourself.
As you'd expect, Zachary Scott is very smooth in the role and plays the sort of jerk you often expect from him. He was excellent in such parts. As for Phyllis Thaxter, she also seemed very good at playing nervous and mentally unstable sorts of roles and is very good here as well. As for the script, it's very tense and original. BUT, there is a problem...there really is no twist at the end. It just looks as if the writer had no idea what to do and left it undone.
