Fivepenny Mystery

An illustration by Gilbert Dunlop from Chapter 8 of Fivepenny Mystery, Defeat of a Greek. Penny's character has developed well and she is no longer the shy girl she used to be. Here she stands up to Agamemnon and questions him about Ainros. Agamemnon is not prepared for her questions and begins to splutter and go pale. Penny remarks to herself that it was "interesting to see him go green and red like that, like a traffic light".
