*Bedroom*
Ka-chak!

"Well, well. Daddy's a policeman" Ryuk remarked as the shingami was sitting on the bed, eating a apple that is in his hand.
"And that must be the reason why you're so confident?" he continue to say as Mia was sitting next to him.

Bite!

"That's right" Light confirmed as he sat down in front of the computer, doing something on it.
"It's easy for me to hack into Dad's computer we're on a home network so I can copy the files I need without leaving a trace. This way I can keep track of their investigation" he explained.

..... ..... .....

Then...

"Here we go" said Light as he was now scanning through various files.
After a moment he smiled, "Well, isn't that interesting?" Light hummed.
"What is it?" Mia asked as she gets off the bed and comes over.
Light lands back in his chair, "Looks like the police are already beginning to suspect a student" he said as she takes a look at the screen.

Laughs

"I guess that means you are in trouble" Ryuk stated.
"If the cause of death is written within 40 seconds of writing the person's name, it will happen. If the cause of death is not specified, the person will simply die of a heart attack. After writing the cause of death, details of the death should be written in the next 6 minutes and 40 seconds" said Light as he remember reading in the Death Note.
"So, what's your point?" he asked with wondered.
"In other words, if I write heart attacks as the cause of death, then I should be able to write down all the details including time of death afterward, shouldn't I?" Light stated.

"Light, you're a genius!"
