While returning from the supermarket, Clara found a poster missing nearby. Several outdated advertisements remained on the same noticeboard, making its disappearance peculiar. She replaced it, then noticed another had vanished beside the pavilion. Across the grass, two teenagers watched her while pretending to repair a bicycle chain on the ground.
Clara approached the park caretaker, Mr. Grady, and described the missing posters. He immediately blamed the teenagers, calling them habitual troublemakers. Clara asked whether he had seen them removing anything. Grady admitted he had not. Still, he promised to watch the pavilion and contact police if their behavior became threatening.
