District Attorney
So now you believe both murders were committed by the same man, eh?
Mike
Yes, I do.
District Attorney
Um... maybe you're right. As you pointed out, there are certain similarities between the two crimes. But you missed one. Perhaps the most important. Both murders were discovered by the same man - you.
Mike
What are you driving at?
District Attorney
Tell me, has there ever been any insanity in your family?
Mike
Listen, I'm as sane as you are. And if you think I had anything to do with it, you're crazy.
