The Twins in the Dump Pit
"The salt field was working through the night. My friend's great-uncle thought it was strange—there were so many people there, so why would anyone need to watch the place? Without another word, he decided to head back."
"But then someone appeared beside the salt field and waved at him from a distance."
"My friend's great-uncle thought the person had seen him, so he waved back. He hadn't expected the person to beckon him over."
"My friend's great-uncle took a couple of steps down the slope, then decided there was no point in going. They might even make him help with the work. So he pretended he hadn't seen anything, turned around, and went back."
"When he got home, he found the door locked. He crawled through a hole in the wall and went up to the attic to sleep. Meanwhile, his family and that relative went to the salt field through the night, searching for him. They didn't find him and didn't return until dawn. The family was sobbing so loudly that my friend's great-uncle woke up and came downstairs. His family was so shocked that they asked whether he was a person or a ghost."
"Then my friend's great-uncle told them what had happened. The relatives who had gone looking for him had also been to the salt field, but they hadn't seen anyone at all."
"Only then did my friend's great-uncle realize that the people he'd seen working at the salt field that night had all been wearing clothes from decades ago. Nobody wore those anymore. And apparently, a major crime had once taken place at the salt field, where every worker was killed. Maybe the people my friend's great-uncle had seen were the ghosts of those who used to work there."
