I got a message from an unknown number saying, “You don’t know me, but I know what you did.” I ignored it. Five minutes later, another message arrived with a photograph of me sitting alone in a café. I was confused because the photo had been taken that same morning.
I asked who they were. They replied, “Ask your friend about the blue notebook.” I immediately thought of my best friend. We’d been working on a project together, and he always carried a blue notebook. I called him. He didn’t answer.
