Current

"The moment you do that... the notebook goes up in flames and all the evidence is completely destroyed."

- Light Yagami

Electric Current (現在, Genzai) is the fourth chapter of the Death Note manga series.

Plot
In the abandoned building, Light takes some items out of his bag. Anyone who touches the Death Note can see Ryuk so it has become a liability to him. Moments later, Light starts a small fire!

Meanwhile, in his room which, aside from some basic computer equipment, is devoid of furniture, L meditates over the latest events. Originally, Kira's victims were reported to have died between 1600 and 0200, Japanese time, during weekdays and varied during the week-ends. L deduced that such hours matched the times that a student would be at home after school rather than an average adult worker or unemployed person. Kira then changed the times of death so that they were spread throughout the day.

L is convinced that Kira became aware of the "student" theory and that means that there is a leak in the Kira Task Force. Kira appears to want L to know this but the reason is unclear. In any case, something is going to have to be done about the matter.

Meanwhile, Light makes his way to a DIY store in order to buy some stuff with which he will make a suitable place for hiding the Death Note from his family, while at the same time making it easily accessible for himself. Ryuk goes with him, invisible to anyone else such as the store staff.

Ryuk is puzzled. Since Light's father, Soichiro Yagami, is the head of the Kira Task Force, Light can obtain information on the progress of the investigation. What's more, Light can even hack his father's work computer without leaving a trace! With these advantages, he ought to be covering his tracks but instead he is leading L to realize that there is a leak, which is even more of a giveaway than the "Kira is a student" issue.

Light explains that it is all part of a long-term plan to get rid of L! Publicly, L and the police are working together in order to capture Kira, but Light doubts that the officers enjoy working with a person whose real identity is unknown even to them. If L then investigates the Task Force in order to find the source of the leak then this will just fuel the resentment and divide them. Furthermore, Light believes that the police may then actually try to find L and discover his real name and appearance. When this happens, Light will be able to kill L!

At the offices of the Kira Task Force, three of the detectives working on the case go up to Soichiro Yagami and hand in their resignations! They insist on being assigned to other cases or they will leave the police altogether!

It has been established that Kira can kill from a distance through some supernatural power. L has also asked the Task Force to find out if the names and faces of Kira's victims were made public prior to their deaths and this has also been confirmed! If he is ever caught then Kira faces the death penalty for mass murder, thus it is logical to assume that he will kill those hunting for him. The three officers are concerned for their lives and those of their families. They are thus leaving the Task Force!

As they leave, other detectives mutter that they may have a point. L's real name and likeness has never been made public and he is likely to continue in this fashion and only communicate through his computer. Police officers on the other hand have to make their names and faces known as part of their duties and thus are sitting ducks!

L witnesses this scene on his computer which is linked to cameras in the Task Force office. He, however, is simply satisfied with the fact that Kira needs to know the name and face of his victim before he can kill him!



Meanwhile, in his room at home, Light has set up a more secure hiding place for the Death Note, based on the tests he carried out in the abandoned building. In a drawer in his desk he can place the Death Note on top of a thin plastic bag which is full of gasoline. Also in the drawer are pieces of metal attached to electric wires which link to the plastic bag and a small explosive device. This is covered by a false bottom which also has a piece of rubber that keeps the pieces of metal apart.

Light has also taken an ink cartridge out from inside a ball point pen. In order to access the Death Note, he simply has to push the ink cartridge through a small hole in the bottom of the desk drawer. This pushes the false bottom up and keeps the pieces of metal apart.

If Light is ever discovered and his room searched then simply lifting the false bottom out of the drawer will cause the pieces of metal to connect and send an electric current to a device connected to the bag of gasoline. This will start a small fire which will destroy the Death Note! If this happens, Light can claim that it is just an extreme way of destroying a very private diary!

Meanwhile, L has contacted Steve Mason, the Director of the FBI, the leading law-enforcement agency in the United States. L asks Mason to send agents to Japan in order to carry out a discreet investigation into the source of the leak in the Kira Task Force! The agents are to investigate the members of the Task Force and their close friends and families and thus hopefully find Kira!

Conception
