Natalie: So what are we doing here?
Adrian Monk: Do you remember the guy we met the other day, Daniel Carlyle? Well, that wasn't the real Daniel Carlyle. That guy wasn't a violinist at all.
Natalie: He wasn't?
Adrian Monk: Mmm-mmm. I remembered something. He said that we interrupted his rehearsal, remember?
Natalie: Hmm.
Adrian Monk: But the violin bow in his hand was loose, so he couldn't have been playing. Plus I went to the library this morning and I found this. Look. Bay City Quintet. That's the group that Daniel Carlyle plays with. And he said that he had a concert that night. But there's nothing on the schedule.
