Restart the Devil Case

"Considering time," Zhao Yu said, while pointing to the little notebook, "The Devil Case happened at least 15 years ago."

"Yes!" Miao Ying nodded. "SARS erupted that year, didn't it? Sometimes I wonder if SARS was a result of this case..."

"Probably not. I did my homework. SARS started in November, but this case had already begun in the summer of that year!" Zhao Yu shook his head. "But, at the beginning, it didn't attract too much attention!"

Miao Ying said solemnly, "The Devil Case is a horrible serial suicide! I don't know why they give it such a name."

"I don't know either. Maybe people couldn't think of a better term for such a weird thing, so they could only use the word 'devil' to explain it?" Zhao Yu guessed. "In the same area, and in a relatively short period of time, nine suicides occurred. That's definitely not a coincidence!"
