I didn’t call Gordon. I didn’t want to wake him up at midnight to come fix another piece of wood. Instead, I unlocked the side door using the emergency key I kept hidden behind the rain barrel, a key nobody else knew was there, or so I had always believed, and stepped into the dark, quiet house. The air smelled of old dust and cold linoleum. I didn’t turn on the overhead light in the kitchen. I just sat down at the table, pulled my phone out of my coat pocket, and tapped the app Gordon had loaded onto my screen earlier that week.
