Mrs Jennings. Yes! Because I thought you were mad.
Duke. And I thought you were mad. One of us is, certainly!
Mrs Jennings. It isn't me!
Duke. Then why were you laughing in that insane way?
Mrs Jennings [laughing again]. I was laughing to think how surprised you would be if you knew who I was.
Duke. And who are you then? [Impatiently].
Mrs Jennings [hesitating]. Oh, your Grace! you will never forgive me!
Duke. Well, what is it?
Mrs Jennings. Look inside your letter again, your Grace, the one Princess Blakowska wrote to you.
Duke. What is all this mystery about? [Opens letter and reads]. "She will be glad to hear that he has secured the services of an artist like Susan Jennings." Well?
