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.
What are you driving at?
Tell me, has there ever been any insanity in your family?
Listen, I'm as sane as you are. And if you think I had anything to do with it, you're crazy.
