Glare

Glare  (グレア, Gurea) is the eighth episode of the Death Note (anime).

Synopsis
The task force discovers Misora has disappeared the day after her fiance was killed by Kira. The force thinks that she may have committed suicide on her own merit, but L, remembering Misora from his previous case, thinks that she was trying to investigate Kira but was found by Kira before this happened. He decides that the search be narrowed down to the two families that Raye Penber was investigating: the Yagami household and the household of the chief commissioner. L concludes that surveillance cameras must be installed throughout both homes; although the rest of the group believes this will result in a civil suit, Soichiro concludes there is no other way.

Light Yagami soon notices that he is under surveillance by a three-step method he set to see if anyone had entered his room while he was away: a piece of paper in his bedroom door that was visible from the outside; a piece of mechanical pencil lead in the hinges of the door; and a doorknob that only went up to, and closed at 90 degrees, so whenever he left he would lower the handle by a few degrees. By telling Ryuk that he will have to stop giving him apples if he did not find all of the cameras, Light effectively had all of the cameras found in a relatively short time with Ryuk's help.

To continue his tasks as Kira, he hides a mini LCD television in a bag of potato chips. The footage was then evidence that Light was not Kira under the thought that he had no idea about the deceased criminals' existence.

Trivia

 * The famous "I'll take a potato chip, and eat it!" scene was originally from this episode.
