Author’s Notes – The amount of responses to this story is really amazing, and I cannot tell you how much it means to me to hear all of the ideas and comments from all of you. This humble writer thanks each and every one of you for the reviews, follows, and favorites. You guys are fantastic, and I am so happy that our paths have crossed together like this.

I owe all of you a major apology for the delays in this story. My grandfather was recently diagnosed with Alzheimer’s, the fast moving one that they can’t do much for. We’re spending what time we can to help my step-grandmother, and it’s tearing me and my father apart to see such a wonderful man become this person we don’t even recognize anymore. Both of us spend time crying after each visit. In a family as small and close knit as mine is, it’s devastating watching this. We’re attempting to find a nursing home for him, but insurance is a problem so we’re having to try to work the system to get him the care he needs. Also too, my father was in an accident involving a wild pig and his leg while on his motorcycle so I’m taking the bulk of the responsibilities that he usually did. It’s exhausting honestly.

Writing may be slow for a while, but it’s not coming to a halt. This I promise you!

Disclaimer – While I’d like to think I’m pretty creative, I certainly didn’t think up the characters for both Harry Potter and Death Note. I don’t own them!

Chapter Fourteen – Countermove

The assumption that something would change regarding Kira’s habits was proven not long after the conversation L and Harry had the day before. Alerts came in throughout the day, each containing information on time, name of the fatality, and location of the

deceased. Harry had stopped his research in order to help organize the new information since Watari was at the police station. Each new death only made his heart sink further as well as make his frustration with the situation grow.

“L, maybe my memory isn’t the greatest but hasn’t Kira been killing a mixture of prisoners and people that are not in jail?”

The taller male nodded, chewing on his lower lip as he kept reviewing the facts they had been accumulating. He didn’t look pleased at all as he put together the changes that Kira had made to his usual patterns.

“Indeed,” he answered. “Today has been a change from what he usually does. A heart attack every hour of the day as well as using prisoners instead of people who are not incarcerated.”

The wizard turned away from the list they’d been compiling all day, looking grim.

“This is not good,” he said to his employer, who nodded once again. It was a testament to just how focused the detective was as he ignored the plate of treats Dobby had left for them to snack on.

“No, it is not. This leaves a variety of possibilities open, and none of them are ones that are palatable to me.”

Harry knew what he was talking about and brought the issue out into the open. He wasn’t pleased by the thought of the problem that had been laid before them as it meant that they would have to be extremely cautious in regards to how they handled things from this point on.

“We have a leak somewhere, and it’s most likely on the other end of the investigation. Your security is pretty much at the insanely paranoid level so there’s really no way for him to access the files at the House,” he ventured, remembering what the other had said regarding Matt.

“Indeed,” L murmured, staring at the computer screen as he considered the potential ways of handling the situation. “Kira has discovered that we believe him to be a student and has somehow changed his methodology. It was a move I somewhat anticipated, given the preliminary profiles that has been done on him thus far. However, this move he has made has left quite a few openings. The question now is what countermove do I make in return?”

The wizard rose to his feet, going to his room for a moment and returning with an ornately carved wooden box. Settling at a small table, he set up the beautifully carved wizard’s chess set. His movements were noticed by the detective, who frowned a bit at his actions.

“Orion?”

“The best brainstorming sessions I’ve ever had has been done over a game of chess. I’m not brilliant at it, but I can hold my own for a while. Join me?”

L climbed out of his chair, sitting in the one across from the smaller male. He watched as Harry made his opening move, calling out the command and watching as the chess piece moved across the marble board.

“Right, countermoves,” Harry began as L made his move in response to his own. “First of all, what do we know about this situation?”

L’s dark gray eyes watched the chessboard as the wizard contemplated his move.

“There is a leak within the Japanese police department. The leak is able to provide Kira with up to date information as the members of the Kira Task Force learn it.”

The smaller male nodded, calling his move to the board and watching the piece move across to the position it had been ordered to.

“Which means one of several possibilities: someone has opened their mouths where they should not have on accident or on purpose due to being a Kira supporter, Kira is on the task force, or it’s someone accessing the computers.”

“Matt has determined that all of the taskforce members were home when their log in information was given to the servers,” L answered. “Tracking down which computer in each home was used would be fruitless as the task force member could have accessed it themselves instead of someone in the family doing it for them.”

Harry was quiet as L made his move, contemplating the events. His eyes were focused on the pieces for a moment before glancing up at his opponent.

“What is your first instinct in regards to handling this situation?”

A pale thumb was chewed on for a moment as gray eyes examined the board, looking up as he answered the question.

“Bring in an outside team to investigate each member of the task force.”

The wizard fell into an old habit that he, Hermione, Luna, Neville, and one other had done during the war. It was time to ask questions to push the brainstorming into a new level and guide the session. The habit was a nice one to fall back into, knowing that both of them could highly benefit from it.

“Based on what you know of Kira, the profile that’s here now, would he anticipate you doing something like that?”

L frowned a moment, still chewing on his thumb. His mind raced with the information, determining several answers.

“If his intelligence is as close to mine as we have hypothesized, then my actions would be to try to cause discord between the outside detective and the police. If they are too busy chasing each other, then there is no time to investigate my criminal activities.”

The green eyed male nodded, calling out his next move before giving another question to his fellow chess player.

“If you were Kira and wanted to do this, would this mean that you would be aware of any outside investigators that would be investigating each task force member and their families?”

The detective paused a moment, mind suddenly picking up speed. His eyes widened slightly, meeting the emerald ones that were watching him.

“I would be watching for any signs of investigation that might be given to the task force members and their families. The only solution is to set up a scenario that makes Kira believe that he’s pushed me into not trusting the task force while trying to ensure I do not have a problem on the team.”

Harry kept quiet, letting L speak out loud and get his thoughts out. He didn’t mind listening as he knew the other needed to get this addressed.

“The problem in doing this is ensuring he does not realize that we know where he is. That’s one portion of the investigation that I have not revealed to the team in order to give myself an advantage should this situation occur.”

L rose, making a final play that put Harry’s king in check.

“Check mate,” he murmured, heading to his computer. He crouched in his normal position as he took a seat, fingers flying over the keyboard.

The long haired male left the set on the table, moving to his seat near L’s station. He watched, waiting to see if he could be of use.

“Roger, this is L. I need Mello, Matt, and Near at their computers and on a video conference call in five minutes,” the detective instructed.

“As you wish, L. Five minutes,” the elderly sounding voice replied over the computer speakers. There was the sound of the link being broken, and the crouching detective looked over at his companion.

“Do you need me to leave while you talk to them,” Harry asked, knowing that the identities of the three heirs were a high class secret. As he watched, he could see the other male visibly ponder the question before providing the answer.

“No. If something should happen to me, you would be working with them to ensure justice is served. I need you to swear a magical oath that you will never reveal their faces or identities to anyone. You’ll be working with them in the future, and you and Watari are the only two I trust to make sure that they have the correct information. When I am able to form the true task force, I may not have time to interact with them. Add to that, they might be able to help you with research if you need it.”

Harry blinked at him for a moment, feeling something warm inside of him. He hadn’t expected that response at all.

“You trust me with this?”

L nodded, not breaking the stare he held with the other. It was surprising to him that he did trust the other so much, but Harry had proven that he was trustworthy and was someone he was proud to work with. The thoughts did make him wonder at it, but he trusted his instincts and logic also told him that the wizard would die before betraying his comrades. The research done on the man also proved that Harry was that type of individual.

“I do, Harry. I do trust you with this.”

The smile he was given made something catch in his chest, doing funny things to his stomach. L frowned a bit, making a mental note to speak to Watari on it, and then gave a tiny crooked smile in return. He watched as the wand was pulled out from his left sleeve and held into the air.

“I, Lord Harrison James Potter-Black, do solemnly swear on my magic to protect the identities of L’s heirs, keeping them and their existence a secret from all those who would do them harm. As I will it, so mote it be.”

There was a bright flare of light that surrounded the wizard, making L wince for a second. The detective had not expected Harry to take things a step further by ensuring that no word of the existence of his heirs would pass the lips of the wizard. The realization only made that sensation in his chest grow, making him wonder just what that was he was feeling.

“Thank you,” he said softly as Harry put his wand away.

“You’re welcome, L,” the wizard answered just as softly, smiling at him for a moment. The small, crooked smile he received in return made him feel good inside, but he wasn’t able to examine that as the genius’s computer beeped.

The monitor divided into three sections, each showing a young boy. Harry hid his smile, noticing the intelligence in each pair of eyes. It was obvious the children held almost as much genius as L did, and he hoped he’d be able to keep up with the trio should he wind up having to give them information or work with them.

“Ryuuzaki, is it safe,” the blond child asked, noticing the long haired male with his mentor.

L nodded as he spoke, reassuring his protégés.

“It is safe. This is Orion Evans, our expert on the magical world. Orion, these are my heirs. Near, Mello, and Matt,” the older genius introduced, pointing at each screen in turn. “Orion has sworn an oath on his magic to protect your identities and existence. Should Watari or I be too busy to update any of you, he will be the one to do so. You may also be asked to aid him in research, using the resources at the House.”

“What’s his security level,” Matt asked, making Harry frown a bit as he followed the conversation.

“I will provide that later,” L said. “Once you are informed, you will know how to act accordingly. Now that the introductions are done, there are some things you need to know in order to fulfill the tasks I will set you. Have you three been keeping up to date on the case information so far?”

“Near has been,” the white haired boy began. “The profile seems accurate for the data acquired thus far.”

The older one nodded, watching the monitor closely as he began to fill his heirs in on the day’s developments. Harry was fascinated at how the other was using this as a learning tool, though he wasn’t sure if L was aware of it or not. He was patient with them, listening alertly to the questions they occasionally asked, and it was obvious the boys held a deep love and respect for the man.

“L, if you are going to pull a second team in to investigate the police and their families, then this could tip Kira off. We’re going to need to find a way to make him believe that the task force in his area is one of several,” the blond interjected once his mentor had finished his explanation.

“I agree, Mello. That was my thought on this situation as well,” L answered the boy. “However, in order to do that, we shall have to set up a very elaborate ruse so that we do not alert Kira to our knowledge.”

“We can set up dummy task forces and link them to the main database,” the red head began, fidgeting with his goggles as he brainstormed out loud. “It’ll be time consuming, but it’ll prove that there are investigations all over Tokyo as well as other cities in Japan. When Kira notices the agents following him, he will probably hit the database to see if you know where he is. Files can be placed in there with the results of the other teams. They’ll have to be backdated, but that’s not hard to do.”

“The only difficulty Near foresees is if Kira should come into verbal contact with an investigating agent. If the agent tells Kira that there is only one team investigating the police, Kira will be able to determine that L knows where Kira is.”

Mello frowned, listening to his fellow students for a moment before taking a bite of his chocolate bar. He chewed for a few moments before speaking.

“My suggestion is that L tells the agency he calls in to send several teams. One to investigate the task force and the others dispatched to investigate other aspects of the Kira case. However, the team that will be working in Kanto will be told that the other teams are investigating the members of the other task forces,” he suggested.

L nodded, looking satisfied at the suggestions being offered.

“Matt, with Mello and Near assisting you, how long will it take you to create these false files?”

The goggle wearing boy frowned, thinking on the steps needed to get the task done.

“The biggest part of the task is the word processing as each file in the data base needs to have its own unique tone to it. I can pull in several of the students to help with that and let Mello and Near supervise that as well as put the touches on the dating for each team. That’ll leave me time to do the final edit as well as input the data into the Kanto division’s servers without causing a system crash or flagging anyone’s attention to the fact that I’m mucking about in their database,’ he mused. “With everyone working together, added to the fact that most of us don’t sleep much, I can have it all in place within forty-eight hours. Less if things go well.”

“It will probably take that long to call in one of the favors the agency owes me and get the teams their assignments before they are in place. Let me know when it is ready, and I can make sure the agents are in position six hours or more after those files are in the police database,” L answered.

The boys, realizing that was the order and dismissal they needed from him, quickly signed off. Once the room was quiet, Harry shook his head.

“You’ve got some very intelligent heirs there,” he said softly, watching as L pulled up a few screens to scan over some information.

“That is why they are my heirs,” he answered him. “They compete against each other for the chance to hold my position, but I try to ensure they have tasks where they have to work together. The three of them, functioning as one unit, are the perfect replacement for me. The problem is that they have yet to realize it. That is why I placed the call. I could have ordered this done without letting them come up with the ideas on their own, but this enables them to think together creatively.”

“This case provides one hell of a teaching tool,” the wizard said, rubbing his temples as he spoke.

L nodded, picking up the phone to call Watari to fill him in on what was going on. The detective would not make the calls to the agency just yet, but the older male needed to know about the decisions that had been made.

“Indeed and it seems that my heirs are not the only ones benefitting from it,” he answered, acknowledging that he was learning a few things too. He said nothing more, dialing the familiar number and allowing Harry to go back to his research.

The wizard gave a tired smile, picking up a book and getting comfortable in his seat as he began reading once more.

Author’s End Note – Longer chapter than usual but hopefully it somewhat makes up for my lack of posting lately. I wanted to tie in the heirs a bit more and I think that given how things have changed somewhat, this is a good use of resources on L’s part. That and I’m a Near fan. Please let me know what you think! See you next chapter – Laran.
