- Stop! You're hurting my wrist.

- I'm sorry, I...

- Listen to me. I want your help.

- My help?

- I'm Richard Hannay.

- Why... Why, you're the man the police are...

- Yes, but I'm innocent. I swear I'm innocent.

- Listen, you've got to help me. It's terribly important that I be free for the next few days.

- You - you will help me, won't you?

- Yes. Yes, of course I will.

- That's fine. I'm sorry if I hurt your wrist.

- Oh, that's all right.

- Uh, you say the police are on this train looking for you?

- Yes, that's why I forced my way in here.

- Oh, I see. And just how am I supposed to help you?

- Well, they're looking for a man travelling alone. If I stay here with you, they'll think we're together. We'll pose as man and wife... and they won't pay any attention to us. They'll just pass us by.
