CSI: Crime Scene Investigation Season 7 Episode 21

Milton: 'I shot an arrow into the air, it fell to earth, I knew not where; For, so swiftly it flew, the sight. Could not follow it in its flight. Long, long'...
Nick: Sir, that's, that's really sweet.
Milton: That's Longfellow. What do you kids know about poetry?
Sara: Nick, the arrow came in through that window.
Nick: Yeah.
Milton: Even an idiot could see that. (Nick goes out, looks around and finds another arrow, he comes back)
Nick: Hey Sara, I found another arrow shot into the ground near that old tool shed.
Sara: Maybe the shooter got nervous.
Nick: Well, to work in a Brothel you're required to register your fingerprints. So...
Sara: I'm almost done here, I'll catch up.
Nick: Okay. I'll let you know if we get lucky.
Sara (turns to Milton and finishes the poem): 'A long time afterward, in an oak I found the arrow, still unbroke; And the song, from beginning to end, found again in the heart of a friend.' Keep the faith Milton.
