Last Time

Harry has a magical melt down in front of Greg after finding out that Sherlock and JOhn have been kidnapped.

"We shall find them Harry, I promise we'll find them, and those who took them shall pay dearly."

Harry did not respond but he believed him. Harry could hear the steel in his uncles voice and he knew that together they would find those who were holding is dads' and they would make them pay. As for Dumbledore, well Harry would make sure the man got what he deserved. Dumbledore had made a grave mistake when he took those whom Harry held dear, and Harry was going do everything in his power to make the man suffer for it.

Chapter 10

Lestrade looked around the devastation in the sitting room of 221b with a sense of shock and awe. Items were strewn about, furniture was upturned and the random bits of paper were now nothing but ash, though he noticed the cryptic ransom letter had somehow escaped a fiery death. Greg didn't know exactly how the devastation had happened but he was almost certain that Sherlock's son had something to do with it.

Looking at the duo still on the floor Greg was having a hard time reconciling that the usually imperturbable Mycroft Holmes, was the same man who was currently sitting on the floor with no thought for his fancy suite, cradling his distraught nephew in his lap. Under other circumstances Greg would have loved to take the Mickey out of the British Government but right now he had questions that needed answers and a missing Doctor and consulting Detective to find.

"Mycroft what in the Hell just happened, is the kid, I dunno, some kind of telepath or something?"

"The or something Inspector Detective," Mycroft said from his place on the floor, "my nephew is a wizard."

Greg looked at Mycroft feeling gobsmacked "What like-"

"Yes the kind with magic and spells and potions Detective." Mycroft said testily. "and I would appreciate it greatly if we could skip the disbelief and predictable, superfluous questions as we currently have bigger issues to deal with." said Mycroft as he gracefully rose from the floor his nephew bundled in his arms. Greg watched as the man carefully placed the teen on the sofa, gently shushing the boy when he became restless. After making sure the teen was settled Mycroft turned back to Lestrade.

"What you just witnessed was an outburst of accidental magic as young wizards sometimes have a difficult time controlling their magic during time of emotional turmoil, and my nephew is both extraordinarily powerful and highly empathic; outburst such as this are not uncommon for Harry, he is much like his father in that regard." said Mycroft with a wistful smile.

"Unfortunately this show of magic is not likely to go unnoticed by those in charge of regulating the Wizarding population and could complicate the situation especially as it was seen by you, someone who is, or should I say was unaware of the Wizarding World." He continued coolly.

"What can I do to help Mycroft, I like the kid, he is good for Sherlock and John, and I would hate to see him get into trouble for this." asked the detective his stance shifting to one that suggested the man was ready for battle.

"What I need you to do now is to leave; go back to work. You were never here, you saw nothing and know nothing. I can convince them that the reading they got was a fluke, or a misinterpretation of my signature as I have clearance to know about magic, something I will have to look into getting you in the future. Right now however I need you to focus on finding my brother and his doctor. My team will have already started on trying to decipher the message, but we can never have too many minds working on the riddle, now dash before the officials show up." Mycroft instructed his tone leaving no room for argument.

"Wait you just want me to leave? You through all of that at me and then just expect me to get back to work like nothing happened?" Lestrade exclaimed incredulously.

"Yes that is exactly what I expect you to do, for Harry's sake if for nothing else; I will answer any questions you have later just leave."

"Right, fine; but after this I expect a decent explanation, and if your team finds anything on Sherlock and John let me know." Greg said as he left closing the door harder than necessary and sighed in frustration, Mycroft could be a real prick.

Mycroft sighed, pinching the bridge of his nose in attempt to stave off the headache looming behind his eyes, though it would likely be in vain, especially as he would be forced to deal with the imbeciles from the Ministry of Magic at any moment. Bundling his nephew in his arms, Mycroft pulled him against his chest and carried the lightweight exhausted teen to his room, were he placed him gently in bed before rushing back down stairs. Quickly Mycroft fixed himself a cuppa and settled down in what was usually his brother's armchair, to wait for his guests to arrive.

Sure enough not three minutes after he had settled, Mycroft heard the tell-tale sound of Apparition in the side ally and exactly four and a half seconds later this bell rang announcing their visitors. Mycroft heard a brief muffled conversation before the sound of three individuals on the stairs reached his ears.

"Do come in quietly Minister, and I implore your friends to do the same if you don't mind." he drawled as they reached hearing distance.

Mycroft smirked as the sound of the minister's exasperated sputter came through the door, quickly followed by the man himself and two others he quickly identified as Mafalda Hopkirk from the Misuse of Magic office and Auror Kingsley Shacklebolt.

"Mister Holmes you do realize it is customary to let guests knock before allowing them entry." the Minister commented shortly.

"Of course I am aware of such social norms and niceties', I was however more concerned about allowing my nephew to continue resting, he has had quite the trying day. Now what can I do for you gentlemen, it must be important for you to break protocol; it is after all most unorthodox to hold a meeting in my brother's flat when our meetings are usually schedule through Anthia." Mycroft politely scolded.

He knew that the Minister was unaware of his presence in the flat but making such comments served two purposes; one was to simply keep the Minister flustered and off his game therefore giving Mycroft the advantage while it's one job was to aid in the illusion that he was unaware of the reason for the Minister's visit; naturally it worked like a charm.

"I..we... that is to say we had no idea you were here Mister Holmes!" sputtered the red faced Minister."We were simply coming to deal with a case of underage magic in the presence of a Muggle this particular case is repeat offender and requires a visit so we can talk to the delinquent in person. I suppose you are here for a similar reason." the short man said his chest puffed out his confidence returned.

Mycroft gave the man a cold look that only the dark skinned Auror seemed to catch.

"Ahm, With all due respect Minister I do believe that Mister Holmes said that he was worried about us waking his nephew, and if I am not mistaken, the only other person in the flat is Harry Potter."

"I..I what?

"It is true Minister, the only other person here at the moment is my recently discovered nephew, who just happens to be Harry Potter." Mycroft stated nonchalantly.

"How, how is that possible? The boy is a Potter through and through, he was born at Saint Mungo's for Merlin's sake! Surly they would have known if he wasn't a Potter!" exclaimed the Minister looking flustered.

Mycroft raised an exasperated eyebrow and inclined his head in a incredulous manner.

"Surely a man as educated as yourself would know how the creation of a child comes about." intentionally misunderstanding the Minister's statement.

The British Government watched with hidden mirth as Fudge sputtered and flapped about as his face turned an intriguing shade of fuchsia.

"I don't know what you are insinuating Mister Holmes, but of course I know how babies come about! What I don't understand his how the lying, cheating, nuisance that is Harry Potter became your nephew!" the minister shouted gruffly.

Mycroft carefully sat down his saucer and tea cup before rising slowly from the armchair, his eyes stone cold and focused directly on the Minister of Magic.

Taking a measured step forward, Mycroft stood on the verge of invading the imbeciles personal space and when he spoke his voice was that of the Ice Man he was frequently accused of being.

"You listen to me Minister and you will listen well, my nephew is not a liar or a cheat, he in not insane and he is not trying to usurp your reign; he is just a young boy who has seen too much, done, too much and whom has the weight of the world on his shoulders. As for your visit today, I can tell you with all certainty that there was no magic performed in front of a Muggle, only a small magical outburst in the presence of myself, a known squib, after my teenage nephew found out that his fathers' had been kidnapped. Now if that it is all Minister, I have more important things to do than speak with you on non-consequential topics as you slander my nephew."

"Mister Holmes I cannot just ignore Mister Potter's repetitive misbehaviors, and you will address me with more respect, I am after all the Minister for Magic!" fudge bellowed, and in the resulting silence, Mafalda Hopkirk and Auror Shacklebolt wisely stepped away from the Minster eyeing Mycroft Holmes as one would watch a predator ready to pounce.

"The correct form address for my nephew is Mister Watson-Holmes, if you must address him at all, and Minister for your sake, it would be wise if you do not have to in the near future . You Minister have ten seconds to get you and yours out of this flat before you find yourselves escorted out with as much force as is necessary; now turn around and scuttle, you have eight seconds left."

Wide eyed, Minister Fudge glanced about franticly and darted down the steps and out the front door, with Mafalda Hopkirk not far behind. Under other circumstances, Mycroft would have found such a thing highly amusing; unfortunately, today was not a day in which he could indulge in such things, he had a wayward brother and brother-in-law to find.

A deep chuckle alerted him to the fact he was not as alone has he thought, and he spun quickly to face an amused Auror Shacklebolt.

"That man has the backbone of a jellyfish and the brains of a sheep." the dark man said handing Mycroft a card. "This is my card if you need assistance finding Harry's fathers' or if there is ever an emergency you need magical assistance with dial this number and it will contact me directly. Fudge is an idiot to believe what he does about Harry, and while Dumbledore's intentions maybe good, he methods have been somewhat questionable of late."

Mycroft took the card flipping it over in his fingers, "Thank you Auror Shacklebolt , I will keep you in mind should we need magical assistance."

Kingsley nodded, "Look after Harry, he is a good kid but trouble seems to follow him like a Crup pup follows its owner."

"Rest assured, I will look after him to the best of my abilities, now if you don't mind, I do have other pressing matters to attend to."

" Of course, good luck Mister Holmes." Shaklebolt said as he swept out the door.

Slipping the Auror's card into his breast pocket Mycroft picked up the note left by the kidnappers. "Now what have you got to say?"

LLAFOHO

Small time skip

Harry stared at the computer screen in front of him with frustration. It had been nearly twenty-four hours since John and Sherlock had been missing and his only hope of finding them lay in his Uncle's men who were continuously coming up empty handed. It hadn't take Mycroft or Harry long to decipher the clues left in the note, the clues themselves were almost too easy.

The "Bumble Bee" was obviously Dumbledore as his name could be broke down into various parts language meaning bee, the 'dore' was especially telling as it means flying insect that a humming sound, in Old English.

The golden boy who strayed could be no one other than Harry, and the most telling part of the message was the part about the On Afforested lead. Afforested meaning any man made forest but the phrase was actually an anagram that spelled out the Forrest of Dean.

The forest was located in Gloucestershire County in South West England and despite being only110 square kilometers (42.5 sq mi), they had yet to locate John and Sherlock. Mycroft had set a up a command center and Harry was currently watching live aerial footage of the forest franticly searching for any suspicious areas, campsites or trails. It wasn't working.

Harry gripped his inky locks pulling roughly and growling in frustration. Why couldn't they find them, why couldn't Dumbledore leave him and his family alone! Harry took a deep breath and slowly unclenched his fists, he would figure this out. So far there had been no indication that the person who had taken his Dad and Tad, as Harry called of Sherlock and John in his mind, was not a Muggle. The paper was run of the mill copy paper, and the message was clearly written with a ball point pen and not a quill and ink. His Uncle had even mentioned that the note sounded like Moriarty, the Muggle man responsible for his Dad's fall, would write. But if this was the case, why hadn't his fathers' been found?

Harry returned his attention to the screen and watched as Uncle Myc's men scoured the Forest and its surrounding villages and towns. As Harry watched he began to notice something odd; every time his uncles men would come to a spot not too far off of the Village of Bream, the men would stop and go off in another direction. After seeing this happen several times, a horrible hot sick feeling invaded Harry's body. Just because the kidnapper was a Muggle didn't mean he wouldn't have help from a witch or wizard, especially if Dumbledore was as involved as Harry fear , and these highly trained British Servicemen were acting exactly how a Muggle would when confronted with a Muggle-Repelling Charm. Harry turned to ask his Uncle if there was another reason his men might be behaving so oddly, but found him deep in conversation with someone who looked to be of great importance.

Harry's frustration and panic were quickly overtaking him. He was ninety-five percent certain that only a wizard would be able to find his parents, and right now he didn't know any adult wizard that he could trust enough to find his Dad and Tad, but if he went himself, he would probably be walking right into a trap...not to mention his fathers' would kill him for coming alone; but what other choice did he have?

Quickly he jotted down a note for Mycroft, leaving the approximate coordinates and explaining the Muggle Repelling Charm. Harry then casually walked upstairs to his room trying not to do anything that would attract his Uncles attention, breathing a sigh of relief when he made it without incident.

Opening his trunk, Harry grabbed his invisibility cloak, a handful of galleons, the knife that Sirius gave him that could open any door, lock, rope or knot knapsack before shoving his wand in his back pocket, and heading to the loo. He quickly and quietly searched the cabinets for any medical supplies grabbing several fistfuls of bandages, some tape, disinfectant, pain pills and some bottles of water that had been stored in the first aid kit for emergencies cramming all of it into his knapsack. Harry was unsure if he would need or even have the opportunity to use this stuff but he would rather be have it and not needed it, than need it and not have it.

Forcing himself to keep his gait slow and normal, Harry walked back to his room, cracking his door just a bit, as closing it would definitely get his Uncles attention, and that was something to be avoided at all costs. Harry kept walking until he got to the window where he paused to wipe his sweating palms nervously against his trousers before sliding open the windowpane.

Looking down, Harry tried to gauge just how far the drop from his window to the balcony two floors down was, before deciding that it was not worth the risk of injury. Going to plan B Harry, grabbed his broom, mounting it, before covering himself and the broom in his invisibility cloak and carefully hovering out the window and down to the busy street below. After reaching the ground he dismounted his broom propped it in-between the entrance for 221 B and the door for Speedy's hoping that no one would take it, and with one last glance at the place he had come to love more than Hogwarts, Harry walked away headed for the nearest alley he had a Knight Bus to summon, and parents to save.

A/N: I am so sorry for the slow updates, but I think it is safe to say that this will be the new norm as real life is quite demanding at the moment. I have not and will not abandon this story, but it will probably take some time in-between updates. That being said, I think that there will probably be only two or three more chapters and this story will be complete! And I think that this chapter broke through my horrible case of writers block! Yay!

The next chapter will be longer and will be all about John, Sherlock, and Harry reuniting, the bad guys will reveal themselves to our hero and well just the general climax of the story. There will also be more dialogue in the next chapter, hopefully you guys were not to incredibly board by the end of this one. Pleases don't judge it too harshly I literally thought this chapter might kill me and it is not my best work.

Thank you so much for reading, following, favoriting and reviewing, it is much appreciated!
