Sayu crept stealthily to Light's bedroom door. She pulled out a tooth pick and used it as a lock pick. She threw the door open and caught Light by surprise. He made a startled noise and quickly hid a black notebook he had been writing in. "What are you doing!?" he exclaimed angrily.

"I was just going to tell you that mom needs you for something," she said innocently.

"Why didn't you knock? And how did you get in? The door was locked," he growled.

"It was? I guess the lock is broke, cause I opened it without a problem," she lied.

"Well knock next time. Now buzz off, I've got to do something before I can help mom," he said irritably. She 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 is no way he would lock his room for this. I bet he has the real one hidden! She thought excitedly. 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. She tried to pry it open and then suddenly it burst into flame. "Ahh!" She yelled in surprise. She quickly ran out of the room to find her mother.

"Well, I'd say he was hiding something pretty important in there..." L said.

"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 his mom and Sayu staring at him in shock. "What's up?" he asked.

"Your sister said that she tried to pry the bottom part of your desk open and it burst into flame. Did you have anything to do with this?" she demanded.

"Erm, you know Sayu, she's a liar when she thinks it'll get her out of trouble," he said nervously.

"I swear I was not lying! It just burst into flame! It's not like I was carrying matches around!" she 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 a him in horror.

"How is a house fire my fault!?" he exclaimed.

"Yes, dear, please explain," his wife 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! How am I supposed to become god of the new world now!? he screamed in his head.
Needless to say, he 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.
