Slowly, Professor Thompson got up and walked to the windowsill. He gently pushed the window open and looked out. "I have never made a big mistake in my life, and I did it with no malice, but I did kill a person. Since the fire, I couldn\'t sleep every night. Now I\'ve said everything, I feel relieved."

As he spoke, he suddenly seized the edge of the window with one hand, stepped on the sill, and climbed up.

Sophia startled. "What are you doing?"

Professor Thompson gave a miserable smile, "I don\'t want to go to jail in such an old age. I also don\'t want to get anyone into trouble. I\'ll take all the responsibility."

Sophia didn\'t want him to die. She hurried up and said, "Get down. Yes, you made an irreversible mistake, but you don\'t need to die for it. Think about your family, how sad they will be!"

Professor Thompson shook his head, "They\'ll be ashamed of me. People like me…"

Sophia walked slowly to him as he spoke, trying to approach him when he wasn\'t noticing.

"Don\'t come!" Professor Thompson shouted, "Or I\'ll jump right off. I have some words to say, then I\'ll…"

"Get off!" a voice sounded before he finished speaking.

Sophia knew the voice. She turned back and saw Benjamin coming to her, and Albert came behind him.

Albert had been waiting for Sophia in the next room. Sophia thought that Professor Thompson would not talk much if he was there, so she just asked him to stay away.

But later, Benjamin came. Albert had heard about Benjamin from Sophia. He worried about Sophia and came along.

The moment Sophia saw Benjamin, she came to understand everything.

The person whom professor Thompson wanted to protect was Benjamin.

Bridget had told her that professor Thompson had a detective to protect Victor, who was fine in half a year. Now she thought about it, the person who protected Victor was not David but Benjamin.

Professor Thompson was grateful to Benjamin that he would do things for him and hide everything.

Professor Thompson looked desperate when he saw Benjamin, "What are you doing here?"

"Get off right now. You have done enough for me. If you die, your grandson Victor will have nothing to do with me!"

Professor Thompson stayed for a moment and lowered his head down slowly.

Benjamin went to the sofa and sat down. He looked up at Sophia and pointed to the spot beside him. "You must have a lot to ask me, right? Sit here!"

Sophia was about to walk by when Albertstepped ahead and sat next to Benjamin.

Sophia was touched. She knew Albert was worried about her safety.

She sat down next to Albert and asked, "I have a question...Why did you do that? Do you have a grudge against Professor Green?"

Benjamin looked up at her and said calmly, "No. On the contrary, I admire her. She was the only one I admire in the world."

Sophia didn\'t get it. "Then why did you…"

"I\'m just too confident. I didn\'t want to kill him. I just want to prove something to her," Benjamin said slowly.

He looked into Sophia\'s eyes. "I just want her to know that there are perfect crimes in this world!"

Sophia stayed. She seemed to talk about it with someone.

She then remembered that in Odom\'s case, David had said that it was a perfect crime that no one could solve.

She retorted at the time that there was no perfect crime in the world and that what was missing was the eye to find evidence.

If David was just a puppet of Benjamin, then the person she was talking to was Benjamin.

"My thought was simple. I want her to experience a perfect crime. Then I can tell her that there was a perfect crime in the world. Later, I found out that Normand was going to set fire to professor Green\'s laboratory for revenge, and I thought of a perfect plan," said Benjamin.

"I asked Professor Thompson to make a special lock that could trap her in the lab when the fire was on. In case she was burned, I asked Thompson to remove all the combustibles around her. Just gave her a false alarm."

"After that, I could go to her and told her that it would be a perfect crime if I hadn\'t had someone to remove the combustibles. Because the lock was specially made for the crime, there was no such lock in the world and no one would think of that. If things were to come to light, Professor Normand would be the only one responsible. No one would suspect me."

"I just wanted to hear her concede my point of view, that\'s all."

Sophia was shocked.

She couldn\'t believe it, but it was indeed the truth.

All this was just a wayward game for this man.

In the whole incident, no one wanted her to die, neither Professor Normand, who set the fire, nor Professor Thompson, who changed the lock, nor Benjamin, who planned everything.

The lab tragedy was just a coincidence of all these factors.

Benjamin sighed and continued, "Please let Professor Thompson go. I\'ll take the blame. Anyway, I don\'t have any family or friends in the world, I don\'t care where I am..."

Professor Thompson got worried. "No. You\'re my benefactor. If it weren\'t for you, Victor would have been killed. I did it, no one behind me!"

Speaking of Victor, Sophia remembered that Victor almost got killed on the plane.

Benjamin was in charge of protecting Victor then. Sophia thought he was incapable of protecting Victor.

Now she knew it wasn\'t like that at all.

Suddenly, Benjamin smiled, "You want to ask why I didn\'t save Victor on the plane, do you?"

Sophia was surprised. He could see through her mind.

Just then, Professor Thompson\'s cell phone rang. He answered it. Suddenly, his face changed, and he jumped into the room from the windowsill.

"Victor was kidnapped!"

Sophia and Albert jumped to their feet. Only Benjamin, still looking the same, sat there.

"George is crazy. He squandered his money, so he kidnapped Victor and asked Bridget to pay him fifty million dollars. What should I do? Victor is just a kid…"

Benjamin rose slowly and walked towards the door." It was my negligence. Just leave it to me."

Sophia hurried up and said, "I\'ll go with you."

Benjamin smiled, "Thanks. But it\'s not a big deal. I can do it alone."

He looked deep into Sophia\'s eyes, lowered his voice, and said two words.

"Professor Green!"

Sophia was shocked.
