27th Precinct takes over Hogwarts

Dumbledore swears that everything was going according to plan for the greater good but what happens when Harry James Jack Potter, grandson of DA Jack McCoy arrives at Hogwarts when his name was called out for the Sorting in 1991? He thought he left the kid with his maternal aunt to set him up for his destiny, well he was wrong!


Albus Dumbledore sneaked a smile while watching the cohort of 1991 walk in the Great Hall, the little witches and wizards were about to begin their journey into the magical world. He brushed most of them aside as they would be malleable into being future fighters for his plans for the greater good. However, he was looking for one particular student that his plans were currently in motion for, yet he could not find the student anywhere the line.

How very strange at all…. well last he checked earlier that day that the blood wards were working, even if Hagrid did mention that he had not seen the young wizard in training.

"Potter, Harry," the Deputy Headmistress, called out, the Hall went deadly silent with bated breath as they waited for the Boy-Who-Lived to step forward and be sorted into his house. Yet, there was no sudden movement until Minerva McGonagall, re-read the parchment as magic suddenly changed a name to….

"Potter, Harrison James Jack!"

A young man with black hair with hints of reddish and silver streaks stepped forward with a book in his hand, some of the students tried to see what the book was but it was obscured from their view.

"Yes, Professor McGonagall, that is me," the newly revealed Boy-Who-Lived stepped forward with a thick American accent, he was quite tall for his age and his magic commanded respect. He politely nodded to the Sorting Hat and sat on the stool with the Hat placed on his head.

"Good evening, Master Zeus," Harry greeted the Hat, as he perused a case that his grandfather and Aunts Abbie and Connie had asked him to prepare a brief for them that was to be presented to Judge Elizabeth Donnelly the following weekend.

"Good evening Mr. Potter, I see that you have your Grandfather's love for the legal system, don't worry I am bound by the same judiciary rules that apply across the world, so your thoughts and strategies are safe with me." Zeus was surprised that the student was well versed in the legal system, perhaps this was the kick in the arse that the wizarding world needed to be brought to the current century.

"Indeed, my Grandfather found me at his step-daughter's house the night my parents died; however, Dumbledore does not know that he raised me and is yet to pay a visit, which I presume it may be as early as tomorrow," Harry admitted.

"I can see the blood of Salazar, Rowena and Godric running through your veins, the Hogwarts Heir aside from Helga has returned. Perhaps it is time for the grandson of Jack McCoy and the son of Lily and James Potter to claim the throne in Slytherin?" Zeus was impressed that Jack managed to hide his magical side to his colleagues in America to become the most respected DA in New York City.

"I agree Zeus, and on the request of the Founders, may I please withdraw the true artifacts from within yourself?" there was a bit of silence as Harry continued to flick through an encyclopaedia of case law that stemmed from Common Law to Civil and Criminal cases from both the American and English justice systems; to the outsiders, it looked like he was reading a basic charms book.

'The Heir of Hogwarts has returned and is in SLYTHERIN!" Zeus announced to the Great Hall. You could hear a pin drop as the Hall was silent before there was a celebration. Harry took Zeus off and proceeded to collect the Sword of Gryffindor, which transformed into a second wand, the Knife of Slytherin which was sheathed into his left leg and finally the true Crown of Ravenclaw that would only be removed from his head at his own hand.

With those requests complete, he nodded to Professor McGonagall before proceeding to the Slytherin table where a throne appeared at the Head of the Table, with the same magic appearing at Ravenclaw and Gryffindor. There was more uproar at how the castle made the throne appear, but Harry paid no attention to it and proceeded to watch the rest of the Sorting.

Soon it was over, and the Headmaster stood up.

"Welcome to a new year at Hogwarts both old and new, just a few notices that I must give out before we get tucked into the wonderful feast. First year, please note that the Forbidden Forest is out of bounds for not only yourselves but older students. Secondly, the right-hand side corridor on the third floor is out of bounds for the year due to maintenance that has to be undertaken, please heed the warning, failure to do so, will result in severe consequences. Now it is time to eat!" Dumbledore clapped his hands to make the food appear before he sat down, slightly fuming that part of his plans were off-track and that legendary artifacts had been withdrawn from the Hat of which he tried for years to claim and worst of all, Harry was in Slytherin NOT Gryffindor!

Meanwhile, Harry was making small conversation with a silvery blonde girl Daphne Greengrass, the Heir of the Most Ancient and Most Noble House of Greengrass, his Grandfather had told him to try and form a friendship with the girl as he went to school with her Grandfather who happened to be his best friend.

"Heir Greengrass, how is your Grandfather, Lord John?" Harry asked, watching Daphne carefully, wondering if she would get the meaning behind the message. Daphne's eyes widened as she realised who he was talking about, no one outside of the immediate family knew that her Grandfather was in fact a NYPD Detective, it couldn't mean that….

"Am I correct that your Grandfather on your mother's side would happen to be Lord Jack?" Daphne asked in a hushed whisper, correctly deducing that his Grandfather would probably want to make a public statement in the near future.

There was a single nod of acknowledgement, confirming that he was in contact with his Grandfather.

"Munch is well thank you for asking," Daphne replied, slipping into using his alias slightly louder as the House would have no idea who she was talking about so there was no need to be secretive for the time being. "He's complaining that Cragen is running him to the ground and Fin is off helping his son, but Benson and Rollins are working well as a team, how about your family?"

"Well, Snape is not going to be happy but I've actually taken the Bar exam, so I am well verse in the non-magical world and wanted to see where the family went to school for generations, Aunt Abbie and Aunt Connie have been coaching me to present a case to a Judge next weekend, I can't say much but it's to do with a murder case," Harry shrugged, as he continued to eat his dinner, suddenly wish there was more healthier food like the US.

"Sounds interesting, Heir Potter," Daphne replied with a laugh, as she studied the young law-wizard, she wondered if this was the opportunity to drag the wizarding world kicking and screaming into the 21st century. She certainly hoped so, as she wanted to study both magical and non-magical diseases to remove a curse on her family.

Any more conversations that were about to continue were halted as the Headmaster had dismissed the Hall to their dormitories for the evening with classes to start after the weekend. Harry stood up and offered Daphne a hand to leave the table to which she accepted with a curtesy before they made their way to the Slytherin Common Room located in the dungeons.

A certain Potions Master paid close attention to the Sorting and the interactions of the Boy-Who-Lived but was slightly confused, however before he could get a jump on the new Slytherin, a note appeared in his hand. Checking the scroll for any curses, he unrolled it and began to read the corresponding note.

Dear Potions Master and Head of Slytherin House, Severus Snape,

This letter is to inform you that my grandson, Harrison James Jack Potter esq, is required to attend to matters involving the District Attorney Office when he receives a notice by myself, ADA Connie Rubirosa or ADA Abbie Carmichael. A minimum of twenty-four hours' notice will be provided unless a direct order comes from the Judge of which I will contact him immediately via a communication mirror.

I know of the hostilities between my late son-in-law, friends, and yourself, however if you even attempt to stop him from attending his duties that he took an Oath to defend the city as best as he can, I will personally drag you out of Hogwarts and hold you in contempt of court and charge with obstruction of justice.

I, John James McCoy, Head of the Most Ancient and Most Noble House of McCoy, do solemnly swear that this letter is true, so mote it be!

The letter flashed blue, signalling that the contents of the letter was true, which now the Potions Master had no choice but to follow the letter to the law, he would have to inform the rest of the staff aside from Dumbledore as soon as possible. Before he could dwell any further, he resumed reading the letter from Lord McCoy.

Please do not disclose the contents of the letter or Harry's profession to Albus Dumbledore, I believe he may have played a part of how the events of Halloween 1981 and the arguments between the five of you, yes I know about Lily, and she is not happy at all Severus. That man will be getting a visit from me soon.

Lastly please keep an eye on Daphne Greengrass, her Grandfather is a good friend of mine who is acting non-magical in New York as part of the Special Victims Unit. If you ever need assistance of any crime that takes place in Hogwarts and you do not trust the DMLE, send word with Harry or Daphne and Lord Greengrass and I will be there.

Remember the Oath Severus, and Sirius Black is innocent, he was granted protection by MACUSA. Check yourself for holes in your memories. There are a few surprises.

Yours sincerely,

Lord John James 'Jack' McCoy Esq, Head of the Most Ancient and Most Noble House of McCoy
Regent for the Most Ancient and Most Noble Houses of Potter, Peverell, Slytherin, Gryffindor and Ravenclaw.

Severus had no intention of preventing Harrison from attending to his job when needed, perhaps he could seek the young lawyer out himself for advice on how to clear his name and not be tied two Masters, even if one is exiled for ten years. However, before he could contemplate the matter even further, he was bought of his planning and thoughts by an outburst in the Common Room.

"Where do you think you're going Potter, you don't belong here in Slytherin, you belong in Gryffindor!" Draco Malfoy, another Slytherin first year, was literally in Harry's' face, but judging the look on Harry's face, Severus came to the conclusion that he had a plan that could cripple his power base in mere seconds.

"Draco Lucius Malfoy, Heir to the House of Malfoy," Harry barked, his New York accent showing through thickly, Draco cringed at the title, he thought he could've hid that minor details with his mother being a Daughter of the House of Black and use his name to throw around his weight for power and money. "I am the Heir to six Houses, three of which I am descended from the Founders, I outrank YOU! You will find out soon enough why I belong here in this Common Room of Salazar himself, and that I have the blessing of my parents and ancestors when I achieved my goal of being a highly qualified lawyer before I started here."

Here Harry turned to his new Head of House, "Potions Master Snape, judging by the scroll in your hands, I take it that you got the Oath of my Lord and what it entails?" There was a nod. Withdrawing another scroll from his pocket, Harry simply placed it in Malfoy's hand and said, "Mr. Malfoy, you've been served to appear in the New York Court for falsification of documents by Lord Sirius Orion Black, Lord of the Most Ancient and Most Noble House of Black in one month. Quite frankly I am glad that the ICW has stripped the British Wizengamot of their ability to hold a trial until such notice. Now if you excuse me, I need to head to bed, good night all.

Pandemonium blew the Common Room, many of the upper years were yelling at their Head of House to do something to put their new first year in place and punish him severely.

"ENOUGH!" Snape bellowed, already dealing with a headache from the fallout of the order being served to the Malfoy family. He really wanted to disown the Malfoy brat from being his godson, in one move Potter had outmanoeuvred Draco by cutting the power source where it hurt the most and for that he was grateful, he just hoped that he would never direct his ire and bring the full force down on himself, he shuttered to think what would happen if that path ever eventuated.

"Heir Potter is correct that he had the right to serve Mr. Malfoy the papers from the wronged family, in this case Sirius Black," he spoke with a calmed but controlled voice. "As of this moment, as you all witnessed the paper being served, you will find that you would not be able to write or speak to anyone outside this room about the matter, so if I hear that you attempt to warn your parents about interfering in the matter, you could very well experience the wrath of Lord McCoy himself!"

Many of the older students gulped when they realised the severity of potentially incurring the wrath of Jack McCoy. Their parents would tell them stories about how ruthless he was with the law and that he had a high clearance rate and success of conviction. Now that Harry Potter, the grandson of Jack McCoy was here following in the same footsteps as his grandfather, an unspoken agreement was shared amongst the snakes.

Attack the King Cobra at your own peril! It would not be long before the rest of the school would find out how dangerous he would be with just an encyclopaedia of laws and case studies.

This was just the beginning and there was 7 years to go. It was going to be a long 7 years.


Hey everyone,

I know I have another crossover going on Suits/Harry Potter, but I finally have the entire original Law and Order (1990-2010) on DVD and have been binge watching the series and I always wanted to be a lawyer – Jack McCoy was my inspiration back in 2008-09. Alas now I will be aiming for a position as a Paralegal as I just finished my Diploma in Crime and Justice Studies at TAFE Queensland (College) and I hope to graduate in February!

So, the first chapter is here, Harry has pretty much boxed Draco into submission and cut off the money and power. The question is, how did Jack find him and how did he become a lawyer at a young age? Stay tuned and more answers and questions will be revealed.

In the meantime, Merry Christmas and a Happy New Year everyone!

Please leave your thought and what you want to see happen!
