Young Alan Turing
- Young Alan Turing: What's that you're reading?
- Christopher Morcom: It's about cryptography.
- Young Alan Turing: Like secret messages?
- Christopher Morcom: Not secret. That's the brilliant part. Messages that anyone can see but no one knows what they mean, unless you have the key.
- Young Alan Turing: How's that different from talking?
- Christopher Morcom: Talking?
- Young Alan Turing: When people talk to each other, they never say what they mean, they say something else. And you're expected to just know what they mean. Only I never do. So... How's that different?
- Christopher Morcom: Alan, I have a funny feeling you're going to be very good at this.
