“Detectives are only human; we're not Gods that know everything. When detectives tell their theory, in reality, most are rather anxious. Thinking that there's always possibility that they could have missed something, somewhere... But in return, the excitement you experience when your theory's smack bang correct is twice as great!”

“Despite its name, the big bang theory is not really a theory of a bang at all. It is really only a theory of the aftermath of a bang.”

“It often seems to me that's all detective work is, wiping out your false starts and beginning again.""Yes, it is very true, that. And it is just what some people will not do. They conceive a certain theory, and everything has to fit into that theory. If one little fact will not fit it, they throw it aside. But it is always the facts that will not fit in that are significant.”

“Contrary to popular belief, most detectives couldn't detect a heartbeat on a speed addict, but you never know when you might be up against the next Ellery Queen.”

“You're right on the money with that. We're all like detectives in life. There's something at the end of the trail that we're all looking for. ”

“Of course it's very hampering being a detective, when you don't know anything about detecting, and when nobody knows that you're doing detection, and you can't have people up to cross-examine them, and you have neither the energy nor the means to make proper inquiries; and, in short, when you're doing the whole thing in a thoroughly amateur, haphazard way.”
