Karen: What happens next with the case?
Kreizler: More deaths. Today's events guaranteed it.

Sara: Did [John] say anything?
Kreizler: Only mumbled about you're willing to go to avoid either confrontation or conversation, I forget which.

Mallory: I read the papers. I've been expecting you.

Kreizler: The club ... have you been there before?
Karen: Are you asking professionally or personally? I like to keep my mind open to new experiences, new feelings.

Alice: So you like to watch?
Kreizler: Observation is the best form of instruction.
Karen: Next to practice, of course.

John: What do you suppose he's up to?
Sara: Byrnes? Drawing blood all over the city, no doubt. Why engage in police work when violence and intimidation will suffice?

I lost my baby. She was stolen from me.

Libby
