Nick Carter, Master Detective1939

Hiram Streeter:
Sounds like a wild theory to me.

Nick Carter:
Well, it isn't a theory because I don't deal in theories. Look, I'm not a storybook detective with, uh, a highball glass in one hand and, uh, a Chinese proverb in another, nor can I tell you from the ashes of a man's cigar that he, uh, had kippered herring for breakfast and hit his grandmother over the head with an axe. I'm just a New York flatfoot, the product of the McGonigle School.

Hiram Streeter:
What's that?

Nick Carter:
Oh, old Patrick McGonigle, he was an Irish cop when I broke into this business, and he used to say to me, "Nicholas, me boy, don't waste time on theories. Make up your theories after you get your man. Sure, they work out better that way.
