18Sayu crept to Light's bedroom door. The door was locked, but she knew it would be, so she had come prepared. She used a toothpick as a lock pick and carefully unlocked the door. As soon as she had finished unlocking it, she threw the door open. Light, caught by surprise, yelped and quickly shoved the black notebook he had been holding into a drawer. "What are you doing!?" he exclaimed angrily.
"Mom sent me to tell you that she needs you for something," Sayu answered innocently.
"Why didn't you knock? And how did you get in? The door was locked," Light questioned.
"It was? I guess the lock is broke, cause I opened it without a problem," she lied.
"Well, knock next time. Now go away, I've got to do something before I can help Mom," he said irritably. Sayu trotted off until she was out of hearing distance, then she burst into laughter.
I got him good! And now I know why he always has his door locked. He's got a diary! She thought gleefully.
Several Days Later
Light had just discovered that someone had been in his room. He had left the house so he could talk to Ryuk and convince him to search for cameras. Sayu giggled as she snuck into his room. Now I'm gonna find his diary she thought. She opened the desk and found a black notebook. She opened it and read over it. This is boring. There's no way he would lock his room for this. I bet he has the real one hidden! She thought. She searched through the drawer until she noticed something strange about the bottom of it. Light really is smart! He probably made a secret space under his drawer! She thought. As she tried to pry it open, it suddenly burst into flame. "Ahh!" she yelled in surprise. She dashed out of the room to find her mother.
"Well, I'd say he was hiding something pretty important in there..." L commented as he viewed Light's room through the hidden cameras.
"Maybe it was just his diary?" Chief Yagami said hopelessly.
"I believe his Kira percentage has just risen by 70%," L stated.
Sometime Later
Light walked back home with a smug look on his face. You'll never catch me, L he thought. He walked through the door to find Sachiko and Sayu staring at him with wide eyes. "Is something wrong?" he asked.
"Your sister said that when she tried to open the bottom drawer of your desk, it burst into flame. Did you have anything to do with this?" Sachiko questioned.
"You know Sayu, she's a liar when she thinks it'll get her out of trouble," Light said nervously.
"I swear I am not lying! It just burst into flame! It's not like I was carrying matches around!" Sayu exclaimed. At that moment, the front door opened and Chief Yagami came in.
"I'm sorry, son, but I'm going to have to bring you in for questioning," he said sadly. Light stared at him in horror.
"How is a house fire my fault? I wasn't even here when it happened!" he exclaimed.
"Yes, dear, please explain," Sachiko said with a worried tone.
"I'm sorry. I can't," Chief Yagami said. He then handcuffed Light and led him to a police car.
My death note is destroyed! How am I supposed to become god of the new world now!? Light screamed in his head.
Light was interrogated by L for hours until he gave in and started yelling about how it was all pointless without the death note anyway. He was arrested after he had given his confession. He was dragged out of the room, screaming hysterically.
