- Peter Gunn: [narrating] The good and the bad of Al Fusary are a matter of record, and as far as I'm concerned it was mostly bad, but any way you look at it, he was unique - the last of a rare breed to crawl out of a bathtub full of bootleg gin, grabbed a submachine gun and made the Twenties roar. By the truest measure of the underworld, he was a real big shot, and unlike his contemporaries, who ended up in a sack or on a garage floor on Valentine's Day, he beat the odds and lasted until he was a little bit over 60, and he was a big shot all the way. For thirty years the undisputed vice lord of his own personal empire. He was unique - and he was dead.

- Peter Gunn: True.
- Edie Hart: Well, I've saved up a few dollars. I'll buy you a late steak.

- Peter Gunn: She's a friend.
- George Fallon: She should be more discriminating.

- Lieutenant Jacoby: Look, can't you do anything?
