I didn’t know them very well. Just exchanged pleasantries once in a while. Took out their trash once as they asked me to while I was on my way to pay the rent.
I had noticed nobody seemed to be home lately. Usually the lights are on pretty late over there. Only reason I found out something had happened was I mentioned to the handyman that a car alarm had been going off in the driveway at that house the same time for the past three nights. It keeps going for just over an hour then stops.
What’s really spooky is I thought I saw a shadowy figure sitting on the darkened porch several days ago. But it’s been pretty hot the past few weeks, and somebody sitting in the cool night air, even at nearly 2 in the morning wouldn’t be all that unusual.
