"An Ning..." Several people in police uniforms, flanked by the principal and the head of the mathematics department, blocked her path.
In an instant, all movement ceased. The sound was swallowed whole, disappearing without a trace, as everyone turned to look at the newcomers.
"An Ning, thank you for cooperating with the investigation. We felt we had an obligation to inform you that Lin Wanwan's case is unrelated to you."
"Our investigation shows that Lin Wanwan died between ten and eleven o'clock. You weren't at the scene. As for the cause of death, we're still investigating."
An Ning listened and replied politely, "Thank you, Officer."
"You're welcome. It's our duty."
The officers were so polite they might as well have been addressing their own ancestors. And with good reason. After the incident began, several high-ranking officials had personally come to oversee the investigation's progress.
