Hadn't heard about the lights before, but I had wondered whether he was outside, waiting for JO to leave.
What I keep wondering about it that I find it strange that the neighbours didn't hear anything, or notice anything going on. The houses are so close together, it just seems strange. In our neighbourhood, the neighbours notice everything. One day, I cam home in a cab from work because I had caught a virus and was feeling unwell, and the neighbour who lives opposite called to ask whether everything was okay because she had noticed the taxi. Just odd that there could be bloodstains near the driveway, and no one noticed a thing.
