Dr. Bell: Adrian, you've been going back to that parking garage for 11 years. Ever since Trudy died.
Adrian Monk: That's right.
Dr. Bell: You're there two, maybe three times a month. Now, the forensics people have covered every inch of it. So here's my question. Do you believe-- I mean, do you really believe, in your heart of hearts, that there's evidence in that parking garage you haven't found?
Adrian Monk: [sighs] No.
Dr. Bell: Still, you're determined to save it.
Adrian Monk: There's a wall on the lower level. It's a gray wall, and it says "B-5" in big, red letters.
Dr. Bell: What about that wall?
Adrian Monk: It was the last thing that she saw. I can't live without it.
