Conclusion
The Kira Case came to an unusual close when criminals ceased to be murdered. Light Videocq was thought to be the last victim for reasons unknown to Scotland Yard. Some theorized Light came face to face with Kira resulting in his demise. Others believe Eraldo Coil was responsible for the immense death of criminals due to the simple reason that he disappeared after leaving Scotland Yard the day Light's body was discovered. As for L, no one has heard from him since. Many believe this is due to utter shame from the fact that the Kira Case was the only case he was unable to solve.
As for myself, I returned to my estate in Winchester shortly after the closing of the case. A year has passed since the Kira Case was opened. It feels as though I have been home without my comrade for a decade though, in reality, only a month or so has passed. Where he is now, I have not the faintest idea.
Upon beginning this story, I was unsure how to end it. I had no knowledge of what occurred after L and I had split paths. It was not until recently, perhaps a week ago at most, that I received an unusual letter with no return address. Curious, I read it without a moment's hesitation. It read as followed:
To My Dearest Friend and Legal Father,
As you already know, the Kira Case has come to an abrupt close and Scotland Yard is clearly aware of my disappearance. Of course, I will not be surprised if I am to become a main suspect in the Kira Case. It will be interesting to be labeled a mass murderer.
The main purpose of this letter is to inform you, Mr. Wammy, that I am not dead (as you have probably already figured out by reading this letter in the first place). However, I regret to inform you that I will not be returning to The Wammy House for quite some time. You see, I have a bit of business that must be taken care of immediately. I only hope that we shall see each other once again very shortly. Whether or not I will remain a detective (due to the circumstances currently surrounding me) is yet to be decided.
Yours truly,
L Lawliet (that is indeed my true name)
P.S. I have also taken the liberty of describing the events that took place after you and I were separated in an attached document since I am sure you are rather curious to know.
And so ends the most difficult case, known as the Kira Case, of the twentieth century. Where L currently is and what "business" must be taken care of, I have not the slightest idea. However, I am certain L will return one day to reclaim his title as the greatest detective that the world has ever seen.
The End
