Lucius Malfoy POV
Lucius had a terrible month.
His son did averagely in school except in DADA and potions.
A new muggle protection law is about to pass in the ministry that would let every magical law worker able to come to people's house whenever he wants and take away anything that doesn't feels light and with all his Slytherin cunningness he didn't managed to think of one thing that would help him repeal the law.
Which brought the thing that destroyed his month, the diary.
Now, he was never a real supporter of the dark lord. He didn't believe in torture or murder. In fact, he was pacifist, as why should you do barbaric things like those when with bribe and a little bit of blackmail you can achieve the same and make people happy about it.
Yet, in the end, he was also realistic, which was why when he was kidnapped to a secret location by one of his so called friends he made sure he sounds as genuine and fanatic as the rest of them while using his Occlumency to the maximum, and as he always did, he bribed his way to the top to make himself invaluable to kill and he managed to survive the war and even use it to his advantage as he once again used money to make himself invaluable just to the minister this time.
Anyway... with the new law being prepared and not many options, Lucius opened the diary for the second time since he got it and asked for advice.
The first time Lucius opened the diary was Halloween 1981 when the dark mark faded, as the dark lord told him that if it were to ever happen he should write in the diary and ask for instructions.
As he has yet to know the dark lord died, he did as told and when in wrote back with Red colored ink saying 'hey, I'm Tom riddle, he immediately cast several detection charms and figured out what this object was - a horcrux! Something which two things, the dark lord isn't dead and as he was told it this situation to write in the book, he was in a almost death situation and was planing on using Lucius's life to get better.
So Lucius used his last option and turned himself to the ministry saying he was cursed with imperio and the rest is history.
The second time he opened the book he made sure his Occlumency shields are as tight as possible before asking for advice as say whatever you will, the dark lord did almost win the war, and was from the line of Slytherin, he had to have some cunningness in his bones and maybe a different look on life is what Lucius needed to find a way to make sure the law doesn't pass.
But as he wrote in the diary he couldn't help but realize that the dark lord is insane.
He kept talking about killing all the muggles and muggle-borns as the solution of Lucius problems and when Lucius said mudbloods to Draco one day, he understood the book started to affect him.
So he wished to get rid of it but no one was willing to buy it from him and he was really scared to throw it away or destroy it as if the dark lord was ever to find out he was sure to die where in a store he can also buy it back and as long as he has a tracker charm on the book he would always know where it is. But apparently, no one wanted to take a book that every fifth year can who trained a little bit with the dark arts can tell you smelled like death.
And that brought him here, to Flourish and Blotts. The only official book store in the magical parts of Britain, in the busiest day of the year, as both Gilderoy Lockhart and Marcus Potter were signing books in addition to celebrating the 'boy who lived''s birthday. With the plan to slip the book to one of the shelfs he walked inside the store so of course it was at that point that his son had to destroy his plans by acting like a Gryffindor who try acting like a Slytherin.
"Hey Weasley, came here with the hope of getting some money for answering questions about the life of the number one follower of Scarface?"
The youngest Weasley boy's face went as red as His sister hair. He dropped his books into the cauldron, and started toward Draco, but His father grabbed him at the back of his jacket.
"Ron!" said The boy's father, Arthur Weasley struggling to keep him from jumping Draco. "What are you doing?"
It was at that point that Lucius had a new idea to stop the new law from passing, by making the family of the person that pushed it the most a pariah in all the Wizarding Britain and not just with the high class and dark families.
"Well, well, well—Arthur Weasley."
"Lucius," said Weasley, nodding coldly.
"Busy time at the Ministry, I hear," said Mr. Malfoy. "All those sessions trying to pass this law and the planing for raids... I hope they're paying you overtime?"
He reached into The Weasley girl's cauldron and extracted, from amid the glossy Lockhart books, a very old, very battered copy of A Beginner's Guide to Transfiguration.
'This is the best book to hide another book inside.'
"Obviously not," He said, trying to get a rase of anger from them to mask him slipping the diary inside. "Dear me, what's the use of being a disgrace to the name of wizard if they don't even pay you well for it?"
Weasley flushed darker than either His youngest son's or Daughter.
"We have a very different idea of what disgraces the name of wizard, Malfoy," he said.
"Clearly," Lucius said and looked around him to get something more upsetting, his pale eyes straying to Mr. and Mrs. Granger, who were watching apprehensively. "The company you keep, Weasley… and I thought your family could sink no lower—"
Weasley had thrown himself at Lucius, knocking him backward into a bookshelf. Dozens of heavy spellbooks came thundering down on all their heads; there was a yell of, "Get him, Dad!" from One of Weasley's kids, While the wife was shrieking, "No, Arthur, no!", the crowd stampeded backward, knocking more shelves over; "Gentlemen, please—please!" cried the assistant, and then, louder than all—
"Break it up, there, gents, break it up—"
The Hogwarts groundkeeper was wading toward them through the sea of books. In an instant he had pulled Weasley and him apart. Weasley had a cut lip that Lucius was really proud of and he had been hit in the eye by an Encyclopedia of Toadstools. He was still holding the Weasley girl's old Transfiguration book. He thrust it at her, his eyes glittering with malice.
"Here, girl—take your book—it's the best your father can give you—" Pulling himself out of Hagrid's grip he beckoned to Draco and swept from the shop.
As he was walking outside the shop he thought 'a good start of a fine plan'
Harry's POV
As Harry seen the fight inside the book store he smiled and thought 'at least the canon is still useful'
