Oh, just one more thing...

The locksmith's here right now, working on the front door. I was just out there talking to him as though I were the murderer on an episode of Columbo, being debonair like George Hamilton and offering my own self-serving theory as to how the crime might have happened. ("Perhaps it was cumulative damage incurred over many incidents of the lock sticking, leading to a final catastrophic failure.")

I almost hope I get caught. Then I can snap, "That's an interesting theory, Inspector. But unless you have any evidence, that's all it is -- a theory. Now if you'll excuse me, I really don't have any more time for this."
