Ellery: Hi, Penny, having fun?
Penny: How can I? I'm doing my Sonja Henie and you're not even watching.
Ellery: Well, I've been reading.
Penny: I know you've been reading. You were reading at the zoo, you were reading at Schraft's -- I thought we were supposed to be spending the day together.
Ellery: Hah? We are spending the day together.
Penny: Yeah, you with your nose in a book. (Grabs book and scans the open page) I read this one. this is the one where the doctor is the murderer. (Ellery gives her a long stare before snatching the book back)
Ellery: Penny, I promised your parents I'd take care of you today. You're my cousin and I love you. But if you ever do anything like that again, I'll break your neck.
