You're an underpaid civil servant who dreams of chucking it all to become a famous author. You live with your overbearing mother who always seems to interrupt when you're writing a key scene. Who always wants to know why you haven't brought home a nice girl.What you really are is a writer. A brilliant one, too, though like any writer, you sometimes have a dry spell. Your imagination is dark, your inspiration the terrible things that can happen to a young woman traveling alone . . . .Suddenly, success! You win a magazine contest--first prize is publication for your terrifying short story about a horrible murder on an underground train. A director wants to make a movie of your award-winning story and wants your input on the script. A pretty young journalist seems to be taking a personal interest in you and your career.
