“Christine!” The pounding on my front door nearly made me drop my coffee. When I opened it, my neighbor Denise stood there in a bathrobe, shaking with rage. “Did you do this?” she screamed. Outside, her car was completely covered in thick white paint. The hood, windows, mirrors, and headlights were ruined. I stared at it in disbelief, but deep down, I immediately thought about my own car.

Two weeks earlier, someone had covered mine in neon pink paint. Denise had acted shocked and sympathetic, even telling me to call the police. But our feud had been growing for months after her dog repeatedly destroyed my flower beds. When she accused me of reporting her to the homeowners association, things became worse. My trash cans were overturned, my hose was cut, and then my car was attacked. I had installed security cameras afterward. Now, when Denise demanded answers, I opened the footage—and what I saw made her suddenly go silent.
