A mystery

At the police station....

Yu Chen was sitting on a chair across an officer. He said, "Now, Miss Yu. Am I correct?"

Yu Chen nodded.

The officer: "Could you tell me everything that happened that night?"

Yu Chen related her story and the officer nodded. "Your story matches Mr. Mo's and Mr. Si's. Now, does this mean anything to you?"

The officer handed her a transparent plastic bag in which there was a piece of paper. The paper was highly crumpled and looked like someone had held it for long.

Yu Chen: "Officer, may I ask where did this come from?"

Officer: "It was found in Miss Hua's hand. She seemed to have had it before the....."

Yu Chen nodded and looked at the paper. Luckily, there wasn't much blood on it, so Yu Chen could read what was written.

The writing on the paper went like this, 'Do you think you know your friends? Ever asked Kio or Hua what their families are hiding? Come to the chemistry lab, ALONE! Otherwise Mian might get hurt.'

Yu Chen looked up. She said, "It was clearly meant for someone else."

Officer: "We think so too. But what makes you so sure? It might have been a trick to lure out Miss Xi. And there's one more thing, we do not know who is this Mian person."

Yu Chen looked down and said, "The threat was meant for me. I was there target. Mian, is my little sister."

The officer was shocked. "So you mean to say, the threat, the accident, everything was planned out for you. And Miss Xi was the wrong person they got?"

Yu Chen nodded again. She had already assumed that this incident had happened due to something big, but she had thought that maybe it had something to do with the Xi family. Now it seemed like this all was bigger than that.

The officer asked once again, "Miss Yu, if what you say is true. We need you to tell us anyone you can think of who might do this. Can you think of someone?"

Yu Chen shook her head. She was a simple girl from a village, so her family had no enemies. Even at school, no one really hated her. And students would never have the guts to try to kill someone.

The officer said, "Anyway, we would appreciate it if you would be on alert and report anything suspicious to us."

Yu Chen nodded and then came out with the officer.

She went outside the station with Xia and Kio while Mr. Mo talked with the lead officer for the case.

Si Xia: "That paper might have been the most important aspect of the case."

Mo Kio: "....."

Yu Chen: "...."

Si Xia: "What's wrong with you guys?"

Yu Chen: "Nothing, we will talk when Zenghai and Hua are with us."

Si Xia nodded and Mo Kio still did not say anything.

He was acting odd but Yu Chen did not blame him. The paper talked about secrets of Mo and Xi family. Yu Chen could make a calculated guess about what secret of Mo family. So, she thought it better to leave Kio with his thoughts, until Hua woke up, anyway.
