Castle, Season 3

Beckett:
Castle told me that you decided to give the money back?

Martha:
Yeah, well, I tried. Chet's kids refused to take it. They said their father loved me, wanted me to have the money. So, I'm, you know, trying to figure out what to do with it. Everything I come up with seems so selfish and petty.

Beckett:
Well, it doesn't have to be that way. You know, someone once told me that money doesn't change you, it just magnifies who you are. You cared about Chet. Maybe you could do something that would honor his memory somehow.
