Buck Nolan: Don't they also say something about it killing the cat?
Ellery Queen: It was five years ago.

Ellery Queen: What?
The Broadcaster, Marvin: Seven years.
Ellery Queen: Dad, why does the coffee always taste better in your office than at home?
Inspector Richard Queen: Because my secretary doesn't make coffee at home. You do.
Grace: [entering] Excuse me, Inspector, but...
