Author’s Note – I’m sorry for the length of time that has passed since the last update. Life has been hell – plain and simple. Too much family drama and my health reacts to all of it. Let’s just say the muses have not been active so writing has been set onto the back burner for a while. Fortunately, the muses are finally cooperating and I’m able to get some work done! I’m very happy for that.
I decided to take a twist with L and the house Whammy runs so I hope everyone likes the idea I’m working with. Add to that, if I messed up on the story behind the Deathly Hallows, I apologize but the HP Lexicon didn’t really have all the data and there was no way I was going to waste the limited energy I have today in trying to go through that huge novel!
Thank you for your patience and the wonderful reviews. You are amazing, all of you!

Chapter Eighteen – A Magical Lead
Multi-tasking had become something Harry had gotten used to doing over the years. He’d been fairly decent at it before the investigation, but he had become quite the master of it because of everything he had to research and do. He spent a good portion of his day going after any information regarding death and any creature associated with it. Though he made sure to spend his time wisely, going back and forth between that subject and the other topics he was pursuing, something told him that following the trail of the shinigami was the right thing to do.
After the war, Harry had discovered that the Potter library held quite a few books from a family that had married into his main familial line; this family seemed to have a fascination with death. The Peverell family had influenced his life a great deal, and he had utilized some of the material during his research on the Hallows after he’d attained the title Master of Death.
These were the books he went to first once the topic of death had been opened for research. The English lord had not gone through all of the material from the Peverell books before now, having focused on the Master of Death and what that was, and hoped that something about the various entities that were affiliated with Death.
L was pulled from his work by a steady stream of low curses in what sounded like an old form of Gaelic, and both he and Watari turned their eyes to the young man. They could see him running hands through the long mess of hair as he swore, looking unhappy and frustrated as he did so.
“What is it,” the oldest male asked, not used to seeing the typically mild mannered man reacting like this.
“The materials I’ve referenced state that Death created several different types of creatures to aid in the reaping of souls,” the wizard replied. “The problem is the books don’t go into detail, and I’m going to have to find something that dates back to when these books were written or before then if possible. I don’t have anything that old beyond these books in any of my libraries!”
“Is there someone to ask,” L asked, understanding the reason why Harry was so upset.
“I may have to schedule a visit with the Shogun and explain why I need access to records that might not be open to just anyone,” he growled, pacing as he did so. “This also means I’ll have to find a way to handle security so my presence won’t be announced. I doubt he’ll be willing or able to meet me here since I’m aware this Kira situation has their ministry on high alert.”
“Maybe there is a safe half-way point where you two could meet,” the detective suggested, hoping to give a solution for the problem.
“I’ll ask him,” he sighed, rubbing his face with his hands. “I just didn’t want to have to go out in public without glamour spells in place, and it’ll be impossible to do that since it’s a meeting with the Shogun. There’s a good chance they won’t be allowed.”
“I’m certain a compromise can be reached,” Watari ventured. “Why don’t you send him a message, letting him know that you need to speak with him but ensure he understands that you need to remain out of the public eye? He might have a solution.”
Harry sighed again, going to retrieve his writing implements. He wasn’t happy with this, but he knew it was the only option to get access to files that were necessary to find out what was causing all of this chaos.
Once he’d gotten his supplies, the wizard took a seat at his desk and opened the vial of ink. He slowly blew out a breath of air, calming his thoughts before starting to write the letter.
~To the Honorable Shogun,
I thank you for the cooperation you showed earlier in regards to providing the information I needed to navigate the magical side of your lovely country. Though I have been deeply involved in the investigation, I was able to visit Kakumerichi and enjoyed it a great deal. I have hopes of visiting it again if time allows and perhaps have the opportunity to tour other locations.
During the course of the investigation, a clue emerged and I have chased it as far as I can. The references I brought with me are old, but they do not go back far enough for me to try to follow the clue to its end.
Because of this, I must ask for an audience with you to present a request in person as I do not feel this is something I can ask via a letter. The problem is that, outside of my trusted companions, the knowledge of my departure from the UK has been kept secret. I was able to hide my appearance during my time in Kakumerichi to keep the news of my presence in your country away from any of the media agencies. I have no desire to contaminate the investigation so a method of concealment will be necessary.
I place the decision into your hands and hope that you will have the means necessary to protect my identity so that we can have this discussion.
Thank you for your time,
Lord Harrison J. Potter-Black
Head of the Most Ancient and Esteemed House of Potter
Head of the Most Ancient and Noble House of Black
Order of Merlin, First Class ~
Harry dried the ink, then sealed the letter into an envelope before calling for Dobby. The house elf eagerly took the letter, and the young man leaned back in his seat.
“Let’s hope I’ll get a good response,” the wizard said softly. “This has to be the right path of investigation; I know these books and have been through most of them before. I hate that most of the books that pre-date mine are pretty much no longer in existence due to the paranoia that gripped the magical world over the centuries.”
“Books were destroyed due to carrying knowledge they feared,” L asked, already knowing the answer.
“I’m afraid so,” Harry sighed. “It’s stupid and hinders the growth of future generations.”
“Knowledge has always been considered a tool, and the destruction of any implement of knowledge has occurred frequently throughout history in hopes of keeping anything viewed as dangerous away from the masses,” the shaggy haired male said.
“The Nazis implemented it back in World War Two,” Watari added, shaking his head. “I’ve heard of other cultures doing the same at different times throughout recorded history in hopes of keeping the masses ignorant and pliable. The concept of what has been lost because of it is simply staggering.”
“Sheer stupidity,” the wizard groused, sounding out of sorts. “This really puts me at a disadvantage because I now have to rely on the generosity of the Shogun and hope that if he allows me to use the older documents for research then there will be something there of use. I don’t like wild goose chases, but the Peverell books have never steered me wrong.”
“What’s so significant about this Peverell family,” L asked, curious now to find out what it was that had the younger male relying so heavily on these texts.
“You know how I said that the stories about Death show up in nearly every culture?”
Both Watari and L nodded, attention focused on the long haired male and Harry continued with the explanation. This would be getting into an area of his history that was rather painful and problematic for him, but he couldn’t keep them ignorant of certain details.
“There’s a family who actually interacted with Death,” he told them. “Three brothers were approached by Death, who offered them a magical item each. One brother wanted a wand that was unbeatable, and another wanted a way to bring the dead back. The third wanted a means of becoming invisible, even from Death. These items were granted to the brothers and became known as the Deathly Hallows.”
“What happened to these brothers,” Watari asked, curious now.
“Antioch, who owned the Elder Wand, was killed for the wand, and the history surrounding it was bloody and dark. Cadmus wound up killing himself because he had resurrected the spirit of his beloved and could not handle what followed. As for Ignotus, he used the Invisibility Cloak well and lived a full life, handing the cloak to his son and meeting Death as a friend when he was ready.
“Some of the wizarding families claim to be descended from the brothers, and I happen to know that my father’s line is descended from Ignotus.”
“You know this for certain,” L asked, intrigued by the story.
“I do,” Harry replied, sharing something only a select group of people knew. “I inherited the Potter Invisibility Cloak when I came to Hogwarts; the headmaster had been holding it since my father had loaned it to him before his death. It’s an old one and bears a unique symbol on it. I found later that the symbol is that of the Deathly Hallows.”
“So these legends are real,” the detective queried, very curious now. “The other items you mentioned, are they still in existence like your cloak?”
“They are,” the Master of Death informed him, looking off into the distance for a moment. It took every ounce of determination he had to not touch the Black signet ring where the cloak and stone had been placed for safe keeping. The last thing he wanted to do was to give a sign that the Hallows were with him.
“Do you think it’s possible the items might be able to help us if this does end up being connected to something related to Death,” Watari asked him.
Both detective and inventor noted the myriad of expressions that crossed the younger man’s face. It was obvious something was bothering him, and they were rather curious as to what it was. Part of it had to be related to these Deathly Hallows that he had told them about.
“It’s possible, but I’ll be able to know more once I’m able to determine what the lore is regarding the creatures of death,” he answered tiredly. “These are creatures I have no knowledge of, and the rules surrounding them might be different from the other magical creatures I have a working knowledge of. I dare not make any assumptions until I know what we’re dealing with. The last thing I want is to put anyone’s life at risk, and every society of magical beings and creatures have their own traditions. If not approached cautiously, it could become life threatening.”
L leaned back in his seat, watching the other for a moment. To think that this could possibly be a creature associated with Death that could be causing part if not all of this problem was rather mind boggling. Despite the young magical children in Whammy’s Home, he was not used to the idea of magical creatures at all.
This would be something that would take time to acclimate himself to, and he knew he didn’t have a lot of it since the investigation needed to move forward quickly. The detective was keenly aware that he was putting a lot of trust in Harry for this and, for once, he didn’t feel awkward about doing such a thing. That actually reminded him of something, and he turned his dark eyes back to the wizard.
“Orion, there is something I have been meaning to ask you. You have proven yourself to have a work ethic that is highly commendable, a strong moral code, and a deep commitment to justice, and all of these are traits that the Organization I work with are looking for. I would like to extend an invitation to join the Organization.”
Harry looked back at him, deep green eyes meeting dark grey ones as he questioned the pale man.
“What Organization is this,” he asked, sounding a bit confused.
“L is a title,” Watari said softly. “The sharpest mind in the world honed to solve puzzles that no one else can solve and is dedicated to ensuring justice is served. The Organization was created to support L, bringing in talent that can provide information and services that L will require to solve the cases put in front of him.”
“How long has this been going on,” Harry questioned, amazed by what he was hearing.
“Generations,” the oldest male told him. “My family has always supported the Organization and opened their homes to those who meet the requirements needed to either succeed L or take a place within the Organization.”
“Which is why you have heirs,” the wizard commented, looking back at L. “I had wondered but figured it was just one of those odd quirks. Now I understand.”
“Exactly,” the detective answered quietly, hoping for a good answer regarding the invitation he’d extended to the other young man.
Harry looked back and forth between them, contemplating what he’d been told. He had a feeling it wasn’t just his dedication that was the reason for the invitation, and he questioned them on it.
“You’re hoping to utilize my resources for adding magical contacts to your Organization, aren’t you?”
“I won’t lie,” Watari replied, being honest with the young lord. “We do have contacts in your world, and those are slowly growing. However, none of them have the influence that you do being who you are in terms of wizarding nobility.”
“The fact the public still feels grateful to the ‘Man-Who-Lived-And-Vanquished’ is a plus in adding me as an agent for this Organization,” he commented dryly.
“There is that,” the elder male replied, watching the man closely.
“If I agree to this, what exactly will I be expected to do,” Harry asked, curious now and grateful Watari had been so honest with him.
“Mostly what you’re doing now,” L answered. “If a case like this comes along, your magical knowledge and expertise will be asked for. There may also be requests for your help with security, and I have also found your presence to be stimulating in regards to focusing on cases.”
“Seriously?”
“I am speaking the truth,” the detective told him. “You did not hesitate to show me the error in some of the plans I had made and in so doing, the investigation has been able to progress without the threat of Kira knowing that I am getting closer to him. Add to the point that you have been able to provide inspiration to me. I find that to be invaluable.”
“So basically, you want me to tag along at times to be Watson to your Holmes,” Harry asked, watching the shaggy haired genius.
L chuckled, recognizing the source of the question. The wizard had it right; he was the conductor of light that the detective needed to keep himself on point regarding the case he was on.
“You are a conductor of light,” he agreed, chuckling softly. “However, I also find you to be a source of light on your own as well and I need that.”
“Right, if I agree to this, I take it there’s a contract of sorts?”
“There is,” Watari answered, hiding his smile at his ward’s comments to the wizard. “However, I can go through it with you later and help draw up something that will be workable for both you and the Organization.”
“I think I can go along with that,” Harry said, turning his eyes back to L. “I’ll do what’s needed if I find it follows with what I believe in, but I also reserve the right to kick your arse if you look like you’re about to do something stupid. Deal?”
“Deal,” L agreed, laughing again as he did so. He was very pleased with the decision that had been made, and Harry would be an excellent addition to the Organization.
Author’s End Note – Another chapter done and I hope it’s one all of my patient readers have enjoyed. I was looking for my manga while I was unpacking as I needed the time line in the final book. Although I’m slowly pulling away from the time line, certain events have to happen before I can put more of my unique twist on things. Anyway, thank you for reading and please let me know what you think of the chapter. See everyone next time! Laran
