John closed the door behind them.  He crossed his arms in a casual manner as he turned to Snape.  “Do I need to explain?”

Snape crossed his arms in a less casual manner -- letting John know that he was definitely still pissed about being shouted at and ordered around by his former student.  “No, he’s always used his mind palace.  Mycroft has one as well, though I don’t think his literally took the form of a palace like Sherlock’s.”

John chuckled.  “Weird, I’ve never thought about Mycroft as a student.  Jesus, he must have been a right twat.  Did he already have a god-complex then?”

No reply.  Snape continued to glare down at John, but gave no indication of an answer to his question.

The Gryffindor laughed to himself.  (He knew laughing out loud would be pushing it.)

“You’re not one for small talk and reminiscing are you?” he asked.

Again, Snape said nothing.

John sighed.  He wasn’t afraid of the former Potions Master, but he did respect him.  This man wasn’t just his old professor, he was the spy that managed to protect Harry Potter and undermine Voldemort from behind enemy lines and all while the Order -- including himself -- hunted him down and the other Death Eaters tried to get rid of him by any means possible.

For the first time since they arrived, John really took in Snape’s appearance.  He looked tired, even more so than when John was a student.  Like he hadn’t slept since the end of the war.  It was nearly 3 a.m. when they got here, but Snape was still in his day robes.  His clothing was quite similar to the ones he always wore: black with many buttons and layers.  But now there was a light, black scarf tied around his neck.  It was loose on one side, as if he messed with it a lot.  

Sticking out ever so slightly on that side was the top of a gnarly looking scar.

It may have been the only way to get them to stop bitching at each other, John thought, but he didn’t deserve that disrespect.

“Look,” he began awkwardly, “thanks for helping us with the case and all.”  He paused, looking for any kind of reaction.

Snape’s eyebrow hitched in such a way that John could actually hear “go on” in his voice despite the fact that his lips were tightly shut.

“And I’m sorry,” he continued.  “For intruding so late at night.  And for the way I spoke to you earlier.  All that needed to come out so Sherlock could focus on the case -- and not blow up your lab.  But it was completely uncalled for and I apologize.”

Snape glared into his soul until John started to wonder if he was going to be hexed.

Finally, Snape turned away and started walking towards the kitchen.  “Tea?” he called back over his shoulder.

Before he could answer, there was a knock at the door.

John’s head snapped towards the sound.  He reflexively drew his wand.

Snape reappeared at his side, gripping his own wand.  They exchanged a look.

“Do you sense that magic?” John whispered.

Snape nodded.

Another knock.  A rather impatient one, this time.

They started forwards, John putting himself in front of Snape as they approached the door.  He looked at Snape and gestured towards the handle.

Understanding, Snape cautiously grabbed it and -- after John nodded -- yanked it open.

John thrust his wand under the newcomer’s chin.

“Really, Dr. Watson?  Is that completely necessary?”

“Mycroft?!”  John stared at the elder Holmes in unabashed disbelief.  “What the hell are you doing here?”

“Well, I believe that’s quite obvious, don’t you think? Even for you.”  He tapped John’s wand, which was digging into the soft skin under his jaw after that last insult.  “Do you mind?”

John lowered his wand, gritting his teeth.

“Thank you,” Mycroft smirked.  He pushed past John without waiting for an invitation.

He looked around momentarily with a curious expression before acknowledging Snape, holding out a hand to him.  “Nice to see you again, Severus.  Long time no see.”

Snape crossed his arms again, fuming.  “Do not call me that name, Holmes.  But do explain exactly why you’re here.  Given what I’ve read of the Consulting Detective and Dr. Watson, your assistance -- though I doubt that’s what this is -- is not normal.”

He’s read about our cases? John pondered.  Has he been keeping tabs on Sherlock?

Mycroft sneered, flexing his hand as he dropped it.  As much as he hated showing true emotions, it was very obvious when his ego was damaged.

“Yes,” he replied, not agreeing to anything in particular.  “Very well.  I’ve been put in charge of making sure this case is solved and covered up in a timely manner.  I don’t believe I need to explain the severity of the situation what with three muggles having been murdered by a wizard with an experimental potion.  Things would get very messy for out kind.”

Snape breathed a short laugh.  “I rather thought it already was.”

John couldn’t help but laugh at that.

Mycroft clenched his jaw.

“NOIRE MORALES!”  Sherlock burst into the living room, shouting in a french.

All three men turned to face him, each wearing an expression of shocked confusion.

Sherlock locked eyes with his brother and stopped dead in his tracks.  The wild look of building triumph faltered slightly.  “What the fuck are you doing here?”

John put his hands up, stopping whatever sarcastic jab formed on Mycroft’s sharp tongue.  “Nope, we don’t have time for that.  Sherlock, what is ‘noire morales?’”

Sherlock eyed Mycroft for another moment before deciding to leave it alone.  “It’s a calling card disguised as a name.  I’ve come across it a few times over the years in cases involving potions, but none of them were of much substance.  Boring stuff that took even the Ministry and its minions minimal effort to deal with.  The cases were never interesting so I never followed up on them, though I always believed that those cases were just a warm up.  Just practice.  I shared this with the Ministry and they assured me they’d keep tabs on it.”  He locked eyes with Mycroft once more.  “But clearly they have not.”

For the first time ever, Mycroft did not take the opportunity to bite back.  Quite oppositely, he was listening intently and seemed to agree.  “It makes sense,” he said.  “But are you sure this is the same person?”

“Yes.  From what Snape told us about Margery Kentworth and this potion of hers--”

“That potion is the doing of Margery Kentworth? I knew she should have been dealt with sooner.

Sherlock gave him a pointed look.  “Do you mind?”

Mycroft held up his hands.  “Sorry.”

Rolling his eyes, Sherlock continued, “She’s cruel and cares little for the lives of others.  However, she’s never actually killed -- at least, not that we know of.  The major commonality in the Noire Morales cases was that that was the name the attackers gave as their supplier.  There was only one other that I suspected to be by the same potioneer with no middle-man, but it was fairly harmless.  Not interesting at all.  I passed on the information as well as my theory, but did not pursue it.

“That potion is far more refined than the original scribbled concept that you showed us, Snape.  But it still isn’t perfect.  Meaning, it’s better from improved general skills, not from actually practicing the potion itself.

“You said Kentworth’s motivation was to alleviate boredom.  What if she got bored of testing minor illness potions and selling them?  What if a client asked for a potion to kill Muggles, and she was finally so bored that she agreed and decided to recreate her school-hood brainstorm to see if it would actually work.

“It even fits the name.  ‘Black Morals.’”

  A shiver ran down John’s spine as they appeared on a dark, empty street that had nothing to do with the frosty air.  He could feel the ancient, dark magic permeating this place in his very core.  Any wizard that stepped foot here would have to have felt that horrible things had happened here, even if they’d never heard of it before or stumbled upon it by accident.  It wrapped around them and made its presence known, like a heavy, weighted blanket -- but without the comfort.

  And yet, it looked so normal.  By all appearances, this was just a quaint little Muggle village, no different from any other modern country village.  Street lamps broke up the grey darkness of the pre-sunrise hour with warm light.  Cars dotted either side of the street.  Every house could see around them was old and obviously full of history, despite evidence that they were well taken care of.  They clearly showed that the locals had pride in and loved their village.  A few of them even had Christmas lights up already.

  But John could not shake that eerie, haunted feeling.

  “You can feel it, can’t you?” Sherlock asked, having observed John’s discomfort as he took in his surroundings.

  “What?”  John knew exactly what he meant, but he needed Sherlock to be the one to say it.

  “The dark magic,” Sherlock breathed.  “A lot of it.  It’s often the first thing wizards notice when they come here.  Not all wizards, mind you, but most.  The first time I came here, it was all I could do to focus on anything other than the oppressive evil that lingers in the atmosphere.”

  Snape, meanwhile, was visibly becoming more agitated.  His knuckles were bright white from the way he was strangling his wand.

  Noticing his unease, Sherlock set off at a controlled, brisk pace.  “Come,” he said.  “We’re only a few streets away/”

  John and Snape fell into step on either side of him.

  “The Potters’ murder wasn’t the only thing that happened here, was it?” John guessed.

  Sherlock cut his eyes towards Snape for a split second before answering.  He expected a reaction to John’s blunt words; yet, he wasn’t surprised when he saw none.  “No, it wasn’t.  Several things have happened here.  For instance, this is not only where Dumbledore grew up, but Godric’s Hollow is also where he first fought the dark wizard, Gellert Grindelwald.  During which, his little sister, Ariana, was accidentally killed in the crossfire.  Both were using dark magic -- including The Killing Curse.  Whether he ever figured out which of them killed her, no one knows.  At least, not to my knowledge.”  He looked to Snape, wordlessly asking for confirmation or correction.

  God, you’re such a Ravenclaw, John thought.  In your thirties and still teacher’s pet.  He suppressed a chuckle.

  Snape shrugged.  “He never really spoke about it.  Maybe a murmur here or there towards the end when he knew he was dying from the curse on the Gaunt Ring horcrux.  He became obnoxiously sentimental and forlorn, then.  For the things that mattered to him, anyways.”  The last sentence was spoken through his teeth.  He shook his head briefly to regain composure.  “But I never heard him specifically say he learned the answer to that particular mystery.  I don’t think it mattered to him -- he blamed himself, either way.”

  Suddenly, something Sherlock said earlier clicked in John’s head.

  “Hold on.  You said, ‘the first time’ you came here,” he said, frowning.  “But you’ve never mentioned Godric’s Hollow to me.”

  Sherlock paused before answering in a forced tone.  “Neither of us speak much about the war.”

  Snape almost stopped dead in his tracks.  “Why were you here during the war?” he demanded, sounding mostly bewildered, but with a definite amount of concern underneath as well.

  Annoyed that the subject was not going to be dropped, Sherlock sighed, glaring at the street ahead as they continued walking.  “Lu- Lupin sent me.  For the Order.  He’d heard of a strange disturbance here in a brief story on a Muggle radio, just in passing, and then nothing else about it.  Obviously, he was familiar with Godric’s Hollow, given his friendship with the Potters.  It struck him as odd -- he never believed in coincidences.  So, he sent me to check it out and told me not to say anything about it to anyone.  He thought it might have something to do with what Harry Potter and the other to were up to.  As protecting Harry Potter was the highest priority for the Order, even though we had no idea where he was or what he was doing, I was to cover it up if I found any evidence of them.

  “Immediately upon arriving, I could sense Potter and Granger’s magic as well as a lot of dark magic -- both old and new.  I followed it to a house that had clearly been a battleground, where I did find evidence of both Potter and Granger -- and Bathilda Bagshot’s horrible mangled corpse.

  “After sending a Patronus to- to Lupin to tell him what I found and to ask for assistance, he sent Mycroft and we covered it up.  Besides a debriefing with him when we returned, we never spoke of it again.”

  All of this was spoken at a rapid fire pace.  Normally, this speech pattern was because his mouth was trying to keep up with his brain.  But this time, it was different.  This time, it was more like he needed to get the words out as quickly as possible.

  John and Snape reeled from this flood of information.  Neither of them knew how to respond, but they wouldn’t get the chance to figure it out just yet.

  Sherlock signaled for them to be quiet as they turned a corner and went to the second house on the right.

  Kentworth continued to scream at Sherlock as the Aurors made the arrest, calling him -- and John, Snape, and Mycroft -- every insulting name there is...and more.  He ignored her.

  “You’re looking for Amadeus Klint,” he told Mycroft, talking out his mobile and texting him everything they’d been told in detail.  “No doubt he’ll squeal like a pig the moment you pick him up, if he doesn’t turn himself in first.”

  “Why don’t you just write it all down?” Mycroft sneered as his pocket buzzed, prompting him to pull out his own mobile.

  Sherlock rolled his eyes.  “I just did.  Don’t pretend you’re not addicted to your mobile or prefer its convenience.  There’s no bottle of ink rattling in your coat either.”  He tapped on another name and paused, thumbs poised.  “What information should I give Lestrade?”

  He was still still speaking very fast.  His part -- the interesting part -- was over; he’d solved the case.  The rest of it was boring and tedious, and took away from the time he could spend looking for a new case.  As always, the faster he passed off this case, the better.  For everyone.

  “The name, that I’ve ordered the arrest, and that I’ll contact him later today to give him later to give him what he needs to take credit for the arrest.”

  Sherlock’s thumbs flew as the older Holmes spoke.  Without another word, he walked out of the house as he hit send and returned the mobile to the pocket of his trench coat.

  John nodded briefly to Mycroft before following Sherlock with Snape right behind him.  When they fell back into their paces on either side of him, he abruptly grabbed each of their arms and Disapparated.

~ ~ ~

  “DAMMIT, SHERLOCK!  I told you not to do that without warning people!” John complained in a tone that said this was definitely not his first surprise Apparition.  He held his hands on either side of his head while the world slowly stopped spinning.

  “Sorry!” he replied, exasperated.  “I honestly meant to...this time.”

  “Well, you didn’t!”

  “Evidently….”

  Snape, meanwhile, had regained his equilibrium a bit faster than John, though he was no less annoyed.  But, deciding John needed no help in scolding Sherlock for his lack of etiquette, he, instead, took in his surroundings.  He took in the drab alley they’d appeared in, the harsh light of the street lamps offset by the dim rays of the rising sun that found their way between tall buildings, and the hellacious cacophony of noise.

  London.

  “Is there a reason you brought me to this dreadful city?” he asked, nose wrinkling as the smell from the banged-up alley bins reached him.

  Sherlock nudged a now sure-footed John forward to lead the way back down the street they’d taken so many hours.  “Yep, tea.”

~ ~ ~

  Discarding his coat in the general direction of its hook, John stumbled into the kitchen to make a pot of ungodly-strong coffee.  Sherlock and Snape hung up their coats (Sherlock pausing to pick up John’s and hang it properly) before dropping into the two armchairs.

  With an absentminded snap of Sherlock’s fingers, flames flickered up and steadily grew in the fireplace.

  Snape took careful note of this as the detective closed his eyes and finally relaxed for the first time in over a week.

  “You know,” he said in a calculated tone, “I was wrong about you, Holmes.”

  Sherlock’s eyes shot open, brows furrowed and nose scrunched, unsure of what he’d heard or if he’d even heard Snape correctly.  In the kitchen, John dropped his sugar spoon.

  “What?” Sherlock managed nearly a full minute after the word formed on his lips.

  Snape rolled his eyes.  His body was tense, clearly uncomfortable with what he was about to say.  But he powered through.

  “I was wrong,” he repeated, still using the same tone.  He caught Sherlock’s eye and held it.  “We saw an absolute waste of talent tonight.  You’re not it.”

  John saw his own shock on Sherlock’s face -- and so much more.

  “Oh-ho! You’re awake!” a cheerful voice exclaimed accompanied by the clattering of her tea tray.  “I was sure you boys would have been to bed by now.”  She stopped when she realized it wasn’t John sitting across from Sherlock.  Recognition nearly took her breath away.

  Sherlock jumped up to take the tray from her, placing a chaste kiss on the top of her head.  “Thank you, Mrs. Hudson,” he said, more for the timely interruption than the tea.  “You’re a lifesaver!”

  Collecting herself, she giggled at the rare show of affection.  “Oh, Sherlock!  I’m sorry, I didn’t know you’d brought home company.  Shall I get another cup for you, Severus?”

  At this point, our eyebrows may as well be stapled together, John thought, once again seeing his confusion and shock mirrored in Sherlock’s features.

  “It’s alright, Mrs. H.,” John answered for him, brandishing the coffee mug he was stirring (with a new spoon).  “I’m good.  He can have mine.”

  “Alright, dear,” she said.  She dropped a cube of sugar in one of the tea cups and splashed in some cream.  “I hope you still take your tea the way you used to,” she added, handing it to Snape.

  “Um, yes.  Thank you,” he managed.  A defensive scowl was setting in, almost like a reflex.

  “I know I’ve said it before, dear,” she chastised him, “but it wouldn’t kill you to smile once in a while.  Honestly, Severus, I would blame you for Sherlock’s moods -- if I didn’t know his brother.  Compared to Mycroft, Sherlock’s a bit of a peach, really.”

  Laughing to herself, she left the apartment.

  The three men stared after her in bewilderment.

  “Will she ever stop surprising us?” John asked Sherlock.

  “God, I hope not.”

  Following Sherlock’s lead, they put their wands in their pockets.  John and Snape kept a hand on each of theirs, but Sherlock left both hands free, trusting the others to have his back.

  The house he lead them up to looked just as normal and mundanely Muggle as all the other houses on Rosemary Drive.  Small, solar-powered garden lights illuminated the pave-stone sidewalk that ran through the neatly kept lawn.  A few brown leaves were scattered here and there, and a small garden that must have been quite impressive in the summertime preceded the quaint porch.  A metal 42 in elegant script adorned the front door.

  By all appearances, they were walking up the steps to the home of a very social and domestic Muggle family.  It certainly didn’t appear to be the home of someone who deliberately invented a deadly potion and supplied it to a murderer.

  According to Mycroft’s intelligence, however, that’s exactly what it was.

  Sherlock bounced right up to the door as if he was paying an old friend a visit.  He knocked three times and poised himself near the door, just enough to be seen through the peephole, while still being abnormally close.

  Lights flicked on on the second floor, the stairs, and -- finally -- the foyer.  After a few moments in which Kentworth was, presumably, looking through the peephole and assessing the situation, the door slowly creaked open a few inches.

  With the speed of a striking cobra, Sherlock’s hand shot out, forcing the door completely open and took a step inside.  Kentworth took an even step back, a shocked expression flashing across her face before quickly receding again.

  He took a few more steps, which she compensated for to keep the distance between them, creating room for John and Snape to enter, wands drawn by their sides.  Snape closed the door behind them, eyes fixed on the woman he’d deemed as “one of the nastiest Hufflepuffs” he’d ever met at such a young age.

  Now that they were inside, John could get a proper look at her.

  Margery Kentworth was on the shorter side, roughly 162 cm tall, though you would not know it from the confident way she carried herself.  Her curly, blonde hair -- definitely not her natural colour, John noted -- was tied up in a messy bun.  Given her attire, they’d definitely definitely woken her up; black sweatpants, a wrinkled grey tank top riddled with what looked like potion stains, and a black robe screamed of the early morning far louder than she ever could vocally.  

  She had a cool, indifferent demeanor, but, after years of living with Sherlock, John quickly saw that this was calculated.  He could practically see her figuring out what was happening and running through her options -- just like Sherlock does on a crime scene.

  Unlike Sherlock, however, she seemed to be coming up empty.

  Desperately, she fixed her attention on a familiar face.  “Such a pleasant surprise,” she said in a flat voice.  “I had my fantasies about you, Professor, but I must confess I never expected you to be the type to bring company.”  She gave Sherlock and John a once-over.  “Though I’m not complaining -- you have good taste.”

  Snape glared at her, lip curled into a snarl.

  Eyes the size of Mrs. Hudson’s doilies, John’s face convulsed in a mixture of shock, horror -- and a little bit of anticipation of how Snape would respond.  This might be his only chance to witness one of Snape’s legendary, invented spells first-hand.

  Unfortunately, that wasn’t part of Sherlock’s plan.

  The notoriously impatient detective hummed his annoyance.  “Sorry, I don’t do well not being the center of attention of attention.  Especially when I’m winning.”

  At least he knows it, John thought, slightly disappointed.

  “I’m sure I don’t know what you mean, Mr., um....” she feigned.

  Sherlock rolled his eyes, grinning wickedly like a wolf that’s cornered it’s prey -- or a consulting detective who’s cornered an elusive criminal.  

  “Oh, don’t play stupid with me, Kentworth,” he started.  His speech pattern picked up speed with every word.  “You know exactly who I am.  A fact that was made quite clear by your momentary hesitation between when looking to see who was at the door and when you finally opened it.  You gave yourself time to compose yourself after placing your hand on the doorknob.  Very quick, hardly noticeable -- to anyone but me.  Then, of course, there was your biggest mistake: looking past me.  Passing off your attention to Professor Snape, making him angry and uncomfortable in a sad attempt to buy yourself time to come up with a plan to weasel yourself out of this.  But I don’t think I have to tell you that your efforts are pointless -- there’s no way out.  And I suspect you knew that from the instant you recognized me.

  “Given how long you’ve been at large, in business with your little outlaw potioneering, you’ve been quite good at covering your tracks.  No one could prove you were responsible, not even my own brother, Mycroft Holmes.  But you made a mistake.  You couldn’t resist using the potion you’d developed in school -- the one that put you on the staff’s watchlist.  The one you’ve obsessed with ever since.  What could it hurt?  It was finally perfected and you were dying for someone to give you a reason to test drive it.  Surely, no one would recognize it?  It was so long ago. So much has happened since then.

  “And then some poor fool comes along, looking for a way to get rid of some pesky Muggles.  You finally have the perfect chance to test out your brain-child with no repercussions.  Their deaths would be labelled as mysterious by the Muggle authorities -- possibly even covered up by the Ministry even if they can’t identify the potion.  The case would go cold and no one could prove the potion was yours.  Except me.

  “You didn’t anticipate the wizard who worked with Muggle law enforcement as a consulting detective.  Nor could you have predicted that we’d get in contact with the very professor that first raised concerns about your little hobby.

  “God, I hate it when interesting cases turn out to be so boring!”

  Kentworth shook like a trapped rabbit, flinching when he raised his voice with his last sentence.  They could see desperation and panic written all over her face as she tried and failed to think her way out.  She was defeated and she knew it.

  John had the urge to check his watch -- to see how long they had before Mycroft shows up with the Aurors -- but he resisted, knowing it might give them away.  It did not slip past him that Sherlock mentioned Mycroft’s name, eliciting a startled flash of recognition, but did not mention his impending arrival.

  Suddenly, a spark ignited in her eyes.  “But you don’t know who I sold the potion to,” she countered.  “That’s why you’re here.  Otherwise, you would have just sicced your brother and his dogs after me.”  She crossed her arms defiantly.  “That gives me leverage.  You haven’t won yet.  And I would much prefer if you didn’t.”

  Sherlock allowed a poignant pause, making a show of studying her and considering her words.

  John and Snape exchanged a knowing look -- she was playing right into his hand.

  “Go on,” Sherlock encouraged, crossing his arms as well to mirror her posture.

  “I want a deal: I give you his name and you let me go.  Tell your big brother I wasn’t home, trail went cold.”

  “And why would I do that?”

  “Because it will be more interesting for you.”

  Again, Sherlock pretended to consider her words.  “Fine.  You have my word.  Now, give me his name and anything else you know.”

  She hesitated a moment, looking for signs of trickery from any of the men in her foyer, before deciding to take Sherlock’s word.  Her shoulders relaxed.

  “Amadeus Klint.  Fairly ordinary.  Didn’t say much about himself.  None of them do ‘cept a few stray, lonely morons.  Said he needed a potion to take care of some Muggles, his neighbors.  He’s a mumbler, so I didn’t understand much of what he said, but -- from what I could understand -- they disrespected him...in some way.  As well as just being annoying.  He repeated that last part several times.”

  The air left John’s lungs.

  “You supplied a lethal potion to someone because their neighbors were annoying?!” Snape seethed, completely horrified.

  Kentworth shrugged, clearly excited to have another opportunity to mess with him.  “Sorry to disappoint you, professor.  I’ll be happy to make it up to you,” she said with a wink.

  With an emphatic flourish, Sherlock checked his watch.  “Fortunately, I’m afraid there’s no time for that.”

  Half a dozen loud cracks ripped through the air. 

  Kentworth whipped around the door burst open and five Aurors surrounded her.  Mycroft was right behind them, vindication exploding across his face when he saw Sherlock’s smirk.

  “YOU GAVE ME YOUR WORD!” she screamed.

  Sherlock pulled an expression of mock regret.  “I lied.  My way is far more interesting!”

  Snape’s whole body went rigid -- more so than usual and certainly more than most of them had ever seen.  His eyes lost focus, as if he was suddenly somewhere else, seeing something that wasn’t there in the little Welsh cottage.  Sherlock watched the colour drain from his features with unaccustomed apprehension.

  “Godric’s Hollow?” John repeated.  “Why do I know that name?”  He tried to pinpoint where he’d hear it, but he couldn’t.  Everything that came up felt fuzzy and isolated by large blank spots.  It had to have been from when he was a young kid.

  Mycroft did not respond, seeming almost too afraid to speak lest he make Snape’s current state worse.

  Their roles now reversed, Sherlock bore the same expression Snape had after learning about Sherlock’s extensive history of addiction.

  Not taking his eyes off of Snape, Sherlock filled in the blank spots.  “Godric’s Hollow,” he started in a soft voice usually reserved for the most critical of clients and victims, “is where James and Lily Potter were murdered by Voldemore on October 31st, 1981.  And where Harry Potter was marked by him as the Chosen One that same night.  The catalyst for the Second Wizarding War and end to the suffering Voldemort -- and his little henchmen -- inflicted upon the world.”  He hesitated a moment, carefully calculating the situation and his next words.  “It’s where so many lives were changed...permanently.”

  He took a few steps towards him.  “Professor?”

  Snape’s eyes came back into focus.  He regarded Sherlock with a guarded mask of neutrality so well built it was all but physically manifested on his hardened features.

  Unphased, Sherlock pressed on.  “I know the last thing you ever want to do is step foot in that village again.  But we can’t do this without you.  We need you to help us bring Kentworth to justice once and for all, and this killer along with her.”

  John and Mycroft watched on in unabashed amazement as Snape’s mask cracked and fell away.

  Fists clenched, he nodded to Sherlock.  “Then you leave me alone, he added with his signature smirk.

  Sherlock chuckled.  “Yes, then we will leave you to enjoy your retirement in peace.”

  Once again confused, but knowing they were running out of time, John inquired, “So, what’s our plan then?”

  “You, me, and Snape are going straight to Kentworth.  I have an idea of how to get her to confess, but we must do it quickly before she figures it out or flees.  Mycroft will meet us there with Aurors in exactly half an hour.”

  Mycroft clearly did not like taking orders from Sherlock, but he said nothing.

  “Fine, then,” Snape said, steeling himself and taking out his want.  The other followed suit.  “No more time to waste.”

  With four loud, synchronized cracks, they Disapparated.

  Sherlock looked between the other three men as they processed this information and considered his theory.  John was the first to speak.

  “I agree,” he said.  “It all makes sense.”

  “And hiding behind an alias would explain how Kentworth managed to disappear after Hogwarts,” Snape added.  He tapped his forefinger to his chin as he thought.

  Sherlock nodded, enthusiastically.  “Precisely!” He shifted his gaze to his older brother -- the man with both the Wizard and Muggle governments in Great Britain in the palm of his hand.  “What do you think, Mycroft? Does it fit?”

  Mycroft broke from his train of thought, his hand dropping from the side of his face.  He met Sherlock’s eyes.  “Yes, I believe it does.”  An odd look flickered in his eyes at Sherlock’s expression of triumph, but it quickly disappeared as he continued.  “In fact, I’ve believed Margery Kentworth to be Noire Morales for quite some time.  Unfortunately, there was never enough proof.  She always managed to cover her tracks -- nothing could ever be traced back to her.  I do hate it when they are just clever enough.”

  “The aurors couldn’t find a connection?” John asked, baffled.  “How could they hunt down the most skilled and dangerous Death Eaters after the war, but not one potioneer with a weird hobby?”

  Mycroft rolled his eyes.  “Have you not been paying attention at all?”

  John clenched his teeth, trying to think of a solid reason not to hex him.

  Seeing the anger on his anger on his face, Mycroft sighed and explained.  “None of the incidents were all that troublesome.  The supplier -- while, perhaps, questionable and annoying -- was no real threat, even if they did know what their potions were being used for.  It was certainly not enough to be considered a Dark Wizard.  And, therefore, not enough to get the aurors involved.”

  Sherlock looked offended.  “Why didn’t you bring it to me?”

  “Because, as you have so thoroughly addressed, it didn’t interest you,” he retorted with a sarcastic smile.

  Oh, here we go, John thought in exasperation.  He rubbed his sleep-deprived eyes as the two brothers began bickering.

  “You bring me boring cases all the time!”

  “Which you either make John solve for you or you completely ignore.  You refuse to answer to anyone, but you are especially stubborn and petulant when it comes to me.”

  “What the hell is your point, Mycroft?”

  “Exactly what I said!”

  “Ugh! You are so distracting!”

  “Enough!” Snape growled.  He didn’t yell -- he didn’t have to.  The menacing tone of his voice was sufficient to immediately silence them.  “There will be plenty of time left in your lives to continue this incessant squabbling after the matter at hand as been dealt with.  Per the moment,” he paused to level Mycroft with a steely gaze that demanded the absolute truth, “where does she live?  If you have indeed been keeping up with Ms. Kentworth, as you say, you must know where to find her.”

  Mycroft sneered.  “As there’s no point in lying to a Legimens….”

  Snape raised an impatient eyebrow.  “Go on.”

  “Promise me you can prove this is Kentworth’s doing beyond a doubt,” Mycroft stiffly implored Sherlock.  “She can’t be allowed to get away again.  Not this time.  Not as far as she’s gone now.”

  Sherlock nodded, slightly taken aback, but trying not to show it.  He knew this was no simple request to help take down a criminal.  Mycroft was asking him to accomplish what he’d failed to do for years.  It would put a criminal behind bars, yes.  But it would also protect Mycroft’s position and reputation.

  He stood tall and looked his big brother in the eye quite differently than he had before.  “I will stop her, Mycroft.”

  “Very well,” Mycroft replied.

  As he faced Snape again, John could have almost sworn there was anticipation in his eyes.  But, for what, he could not have predicted in a million years.

  “Kentworth’s current address is 42 Rosemary Drive...in Godric’s Hollow.”
