Chapter 92 - 92: Find Out The Truth

Had it not been for the door locked, she would not have been unable to escape.

"I think the killer might have tampered with her wheelchair and got it stuck and couldn't turn." Benjamin said, "If so, she would not be able to escape by herself, would she?"

"No." Sophia refuted.

There was nothing wrong with her wheelchair, and it could move freely.

"Believe it or not, the wheelchair was burned down after that, and the evidence must be hard to find. I have a hunch that the killer was probably someone she knew," Benjamin continued his deduction.

"Hunch?"

"My hunch is always right. I used to use it to solve a lot of cases."

No words from Sophia anymore; in her opinion, Benjamin was at best a smug guy who had learned some detective knowledge from David but had no true learning.

Relying on intuition to solve the case, he might as well go to the fortune teller under the overpass to perform the divination.

The laboratory door was an ordinary iron door with the inside and outside lock. There didn't seem to be anything special. Sophia had checked it the last time she came. Checking it again, she still didn't find anything special.

She never read the police investigation report. And Kevin had not received the closing notice yet. The case was pending. It was neither characterized as an accident nor as murder.

In other words, the police had found nothing to prove it a murder, but it didn't seem like an accident, so they were unable to finalize the case.

If the door had been locked from outside when the fireman arrived, it would have been proven that someone had done it on purpose. The case would have been classified as murder, and there would have been no doubt.

Sophia believed that there must be nothing wrong with the door when the fireman came. They had seen nothing abnormal.

She studied it for a long time and still got no clue. It was time for the exam. She had to give up and turn around and walk out of the lab.

Benjamin shouted behind her, "Are you leaving? I'm gonna find out the truth about this case. I will!"

She didn't look back and just waved back at him in response.

When Sophia entered the examination room, many students were already there.

The No. 12 examination room was a small room for forty people. The students here came from all over the country and were all masters of mathematics. They didn't know each other. No one talked. They were just preparing the stationery for the exam.

After a while, invigilators walked into the examination room with the test paper. 

Sophia looked up, and her eyes fell on one of the teachers.

She knew that man. He was an old professor of Glinton University, named Wilson. He had taught her math when she was studying in Glinton University. She had heard at that time that he often designed questions for the Mathematical Olympiad. And the questions were extremely tricky and difficult.

Professor Wilson took it as a pleasure. If no one could work out his questions, he would be very happy. Every time he finalized the test questions, he asked to go to the examination room to see those math masters from all over the country being caught up in the questions and meditated.

At that time, Sophia thought the old professor was really… a pervert.

But here it was her turn to be the examinee, and she was not relaxed. She worried about coming across strange questions which she could not solve.

Before long, the bell sounded, invigilators handed out the test paper, and students began to write.

Sophia glanced through the examination paper, and there were two difficult questions, which must be from Professor Wilson. She picked up the pen to work on them first. It took a lot of time before she finally worked them out.

Then she turned to do other questions, which were much easier.

Professor Wilson walked around among the examinees, looking at their papers and checking the progress.

When he got to Sophia, he stopped.

He was stunned. He had thought that the two questions were so difficult that even if someone worked them out, it would not be very easy.

But this examinee worked out these two questions first, and the answers were correct!

It was just thirty minutes passed. The examiner had gone back to other questions.

Professor Wilson was old and in poor health. He should retire next year. Before that, he had been looking for a student with a talent for mathematics as his student. It was just that he hadn't been able to find one to his satisfaction.

While the girl in front of him seemed quite qualified, he was very excited, his heart began to beat faster, and he began to feel uncomfortable. He hurried up to the podium to sit down and rest for a while.

But all of a sudden, he felt weak and fell down on the podium.

The other invigilator was so frightened that he hurriedly came forward to hold him, "Professor Wilson! Are you all right?"

Sophia heard the noise. She looked up and saw Professor Wilson fell down. Immediately, she guessed what had happened.

She knew he had a heart attack, and he must have a heart attack.

She immediately ran to the podium to feel his breath and heartbeat.

"No heartbeat… Call an ambulance, sir!"

She laid him flat on the ground and pressed him rhythmically on his chest.

The invigilator obviously didn't understand what was going on, but seeing that Sophia did quite well, he didn't stop her. He picked up his phone and made an emergency call.

"The doctor said... he needs CPR right now!" The invigilator said worriedly, "Or it would be too late when the doctor arrived, you..."

Sophia said impatiently, "What do you think I'm doing?"

The teacher didn't know what to say.

How could he know what she was doing if he hadn't studied first aid?

"You…" Sophia pointed to Professor Wilson's mouth, "You give him two mouth-to-mouth breaths."

"Me? Oh… okay!" Said the invigilator.
