Ironside: When you're investigating a case, and you're suspicious, it is suspicious. You don't waste time checking with me. What about the widow?
Ed: Out of town, she's on her way back.
Ironside: Well, the house isn't out of town. You ought to be tearing it apart.
Ed: Looking for what?
Ironside: You're the one that's suspicious. In this business you don't know what you're looking for until you find it. And you don't find it until you look. And you cannot look here! (Ed leaves)
