Adrian Monk: Do you have the article that Trudy and Janice wrote?
Natalie: Yeah.
Adrian Monk: That's him! That's Jack Bollinger.
Natalie: The union boss.
Adrian Monk: He was their anonymous source ten years ago. Now that they're both gone, he must be panicked that all of their research material will be made public. And his old friends will know that he ratted them out.
Natalie: What about the woman?
Adrian Monk: Bollinger must've just found her. It was a con game to trick Janice's father into giving up that key.
Natalie: I don't- How did she know so much about Trudy?
Adrian Monk: Bollinger must've coached her. He spent time with Trudy when they were writing this, so he knew a lot about her.
