 The doctor was a little late. The police arrived and made noises and were very busy. Mona Walsh didn't pay any attention to any of them. Barry? Yes, Lieutenant? We haven't been able to get a thing. A couple of the neighbors heard the shots but thought they were a car backfiring. That happens. Which gives us the time Mrs. Walsh and the character in the alley were killed. An hour and ten minutes ago. Does knowing that make you feel any better? No.
