- Chris Harrington: Howdy, Smitty! How's the strong right arm of the law?
- Whispering Smith: It's getting stronger by the minute... and let that be warning to you.
- Chris Harrington: As of today, the Denver police force can sit back and relax. I've become a reformed, law-abiding citizen.
- Whispering Smith: Mm-hmm. I'll keep your secret.
- Chris Harrington: You'll find this hard to believe, Smitty, but the most wonderful girl in the world has just agreed to become my wife.
- Whispering Smith: Marry you? She must be out of her mind.
- Chris Harrington: I told her the same thing, but it didn't do me a bit of good.
- Whispering Smith: That's great, Chris. Who's the unlucky girl?
- Whispering Smith: Provin' a man's innocence is as much of his job as proving his guilt, but so far you haven't given us one thing to go on - not one!
- Chris Harrington: I gave you my word I didn't do it!
- Whispering Smith: That isn't enough. You know, it's the hardest thing in the world for a man to get himself accused of a crime unless he's either involved in it or else hiding the truth. Now which is it with you?
- Whispering Smith: Boy, was I ever wrong about that Harrington kid. Here I thought we had an open and shut case.
- Whispering Smith: There's no such thing as an open and shut case, George... just open and shut minds.

- Whispering Smith: [narrating] Even when things looked hopeless for Chris, Alice's loyalty had never wavered. It was a real pleasure to place Chris in her custody.
