A/N: Hello! Today is Tuesday and I am determind (I recently discovered I am determind to do a lot of things) to write a few chapters today. Also, I have decided to share some very Harry Potter news with you. While writing this, I thought you all would like to know I am wearing my deathly hallow symbol necklace and my 'Sirius Black escaped Azkaban' wanted poster t-shirt. And… I WENT TO THE CINEMA ON SATURDAY AND THE UNIVERSAL ORLANDO STUDIOS ADVERT CAME ON! 'The Wizarding World of Harry Potter!' throughout the whole advert I was like, 'I'm going, I'm going, I'm going.' And my friends were like 'SHUT UP!' (For those of you who don't know, later on this year, I am going on holiday to Florida. HARRY POTTER WORLD HERE I COME!) Also, on Sunday, I was in town and I saw this like 8 year old girl wearing a cloak and a Gryffindor tie. 'I was like OMG! YOU ARE MY NEW BEST FRIEND!' she didn't hear me sadly, and my friends then dragged me away… Also yesterday (Monday) I went to the toy store and I couldn't find any toys to do with Harry Potter. Very disappointing. So yes, that is the end of my Harry Potter filled 4 days. And yes, I am on a bit of a hype. So, here's chapter 31 people!

-CONVERSATION OF THE CHAPTER-

ME: Hi!

PROFESSOR FLITWICK: Hello!

ME: So how is your charming going?

PROFESSOR FLITWICK: Brilliant thank you.

ME: Good, good.

PROFESSOR: Is there any particular reason you asked me that?

ME: Noooooo. I'm just being polite. Manners cost nothing right?

PROFESSOR FLITWICK: I suppose you are correct.

ME: Yes, yes I am. So I heard you did duelling?

PROFESSOR FLITWICK: Yes. I do have a fair amount of trophies.

ME: Awesome!

PROFESSOR FLITWICK: Well, thank you.

ME: I'd love to stay and chat about your awards but you have to go now. I think your services might be needed soon.

PROFESSOR FLITWICK: Erh- okay?

*Professor Flitwick disappears*

ME: He he he. ON WITH THE STORY!

31

To their surprise, Remus disappeared for 2 days on the 29th of March.

His 'excuse' was that his grandmother had died. Unless, Remus had 3 grandmothers, it was obvious he was not telling the truth.

Luckily, Remus returned on the 31st, one day before the April the 1st.

'Have you got your 'order' from Gracie?' was one of the first things Remus asked when he returned.

Stopping them from questioning him.

James had a feeling he was trying to do that on purpose.

Nevertheless, he let it go.

'No,' Sirius answered him, his smile turning into a frown. 'I was wondering when Gracie was going to give them to us…'

'How about now?' a familiar voice said.

They jumped from surprise and Peter even fell off his chair.

'How did you find us?' James interjected.

Gracie shrugged and took a seat on an old desk.

They were in a large unused classroom on the 4th floor. It was very dusty and some of the chairs and desks were broken. The corridor outside was very unused and hardly anyone wondered down there.

'I don't tell on my sources James. You should know that by now.' She faked disappointment and blew a large bubble from her gum.

It popped loudly.

'The supplies?' Remus asked, going back to the original question.

'Here.'

He hadn't noticed it before, but a small bag was clutched in Gracie's hands.

She opened it up and reached inside.

Noises, of clanking, banging and shuffling echoed in the bag.

'Ah! Here we go!' she exclaimed.

She drew out a large cauldron and placed it on a desk next to her. The yellow liquid slashed about dangerously but not a drop fell from the cauldron.

Next, she brought out about 50 hugeboxes which contents they could not see.

Then, to almost their horror, she brought out 4 large cannons.

'Are those-?' Remus gaped.

'Yeah,' Gracie said carelessly. 'There not like the one that fire cannon balls at you. They fire smoke.'

'Woah.' Sirius said breathlessly.

James stood up and circled the cannons that Gracie had placed on the floor.

'They'll fill the Great Hall up with smoke. We can place one in each corner of the hall.' He notified.

'Are they already loaded with smoke?' Sirius asked, prodding one with his finger.

Gracie snorted.

'Of course they are. I give my customers what they ask for. Speaking of customers,' Gracie paused and dug into her pocket.

She pulled out 4 small cards.

A bit like the business cards those Muggles use.

She handed one over to each of them.

The card was red, with gold writing and a picture of a lion with Gracie on it.

Confused, he read the card.

*Prewett's Pure Parcels*

Grace Prewett's you need, we get service!

Anything Wizard or Muggle, we can get it for you

Cheap and reliable

Orders can be taken anywhere, anyplace, anyway, (even outside of Hogwarts!) any hour, any minute (Not at night sorry!)

Weeks wait maximum

Prewett's Pure Parcels has the right to deny selling to people (mainly Slytherins etc.)

Prewett's Pure Parcels are not held responsible for any faulty products

Note: Molly, Gideon and Fabian Prewett are not involved in this business.

'Prewett's Pure Parcels?' Sirius grinned.

'Hey! There aren't many good words beginning with P!' Gracie protested.

'Hey!' Peter frowned. 'What about my name!'

'Well, I think it's cool.' James said.

'Thanks James. I've mad loads of cards,' Gracie bragged. 'I'll give them out later.'

'Is it safe to do this? What if you'll caught?' Remus asked.

'Me? Get caught?' Gracie smirked and flipped her hair dramatically. 'Remember who you're talking to Remus.'

She winked.

'So, in total, I paid: 4 galleons for the potion, the 4 cannons all together with the smoke, well I got them cheap, buy 3 get 1 free, so that's total 21 galleons, then the goo that was 2 galleons 10 sickles. So that's 27 galleons and 10 sickles, divided by 5 which is 5 galleons 8 or 9 sickles each…'

'That's loads…' Remus trailed off.

It was obvious Remus didn't have that kind of money to spare. His robes were patched and frayed, obviously second hand. Along with his school books, cauldron etc.

'Look, it is higher than it usually would be because of the cannons. As it's your first order, and as you are my most loyal customers, I'm willing to knock the price of the cannons off, leaving the smoke, goo and potion to pay for. That's 4 galleons plus 2 galleons plus 10 sickles plus 4 galleons… that's 10 galleons 10 sickles. 2 galleons and 2 sickles each please.' Gracie said.

'Thank you.' They chorused.

They dug into their pockets (they had been carrying some coins around, waiting for this moment.)

'Where do you get this money from anyway?' James asked curiously as he gave Gracie 2 galleons and 2 sickles.

'Secret. And before you ask Remus, no, I haven't robbed Gringott's. Actually that would be really cool to do…' Gracie said thoughtfully. 'Some kids are gonna do that in the future and escape on a dragon.' (A/N: Oh you don't know how right you are Gracie…)

'Okay…'

'Anyway, Sirius Easter's in 2 days. You owe me money.' Gracie said firmly.

Sirius sighed and fished out a few coins. 'Here. A few extra as well, treat yourself to something nice.' He said sarcastically.

'Oh! I will thanks!' Gracie chuckled. 'Now back to this prank of yours boys, I'm willing to offer my help setting up for a galleon.'

'I just gave you an extra galleon.' Sirius grinned.

'You should've held onto it a bit longer then Sirius.' Gracie smirked.

'I'll pay.' James offered.

'Why?' Peter asked.

'We need some help. Invisibility charms and all that.' he lied. Secretly, he wanted Gracie to be fully involved in their first proper prank together.

Even if she said she 'didn't' want to be.

Sirius, who caught on, (by now, Sirius and James were quickly becoming like brothers. Being brothers involved knowing what the other one was thinking) agreed. 'Yeah, we need some help.'

James silently handed a galleon over.

'Meet in the common room at midnight, tonight.' Gracie said quietly and then left the room.

As the clock struck quarter past midnight, Sirius, Peter, Remus, James and Gracie were in the Great Hall setting up.

'Do we put the cannons in the corners or in the middle of the walls?' Peter asked.

'The corners. No one will go to the corners. That means they won't get stood on. Even if they're invisible, it doesn't mean they aren't there.' Remus explained.

Each of them grabbed a cannon and pushed (luckily there were wheels) it into different corners of the room, while Gracie stood there.

'No! To the left! A little to the right Peter! Back a bit! Keep it down!' she said.

When that was done, the next 20 minutes was spent levitating (WINGARDIUM LEVIOSA!) the goo above each of the tables.

'Are we including the teachers?' Peter said quietly.

'Of course.' was his response.

Around 10 boxes of goo were about each table (Gryffindor, Ravenclaw, Hufflepuff, Slytherin and the staff table).

They were turned upside down, so the opening of the boxes faced the floor.

'Just waved your wand at them and they should burst open. Just waved your wand at one and all of them will go off, same as the cannons.' Gracie explained as they did this.

'Won't everyone see the cannons when they walk in or happen to look up?' James said questionably.

'Well, Molly told me about this charm that makes a human or an object invisible. It doesn't completely work and it is a really hard spell to do. But we'll just have to hope it works.' Gracie furrowed her brows. 'It's called the Disillusionment Charm.'

Disillusionment Charm: Causes the target to become invisible, or close to it.

Gracie muttered the spell and the boxes full of goo and the cannons became partly invisible.

At first glance, you won't notice something there, but if you stared long enough, you would notice.

No offence to Gracie of course, but the charm could've been better if it had been performed by an older, more experienced witch or wizard.

'It'll have to do.' She shrugged.

'What colour is the smoke anyway?' Remus questioned.

'Pink.' Gracie replied simply.

'Pink?' they echoed in horror.

'Yeah pink. It couldn't be red, gold, silver, blue, green, yellow, bronze or black. There the house colours. Pink was the only colour left. Plus, everyone will think it's a girl or girls.'

'Okay. Well we're done here then.' Sirius decided.

They left the great hall and they glanced behind them one last time.

'Now it's just the potion.' Gracie said.

'We know how to get it into everyone's food-'

'But you don't want me there? That's fine. Really. I know stuff that you don't know about, and I haven't told you. See you tomorrow morning.'

Without another word, Gracie hurried up the Marble stairs and out of sight.

So much for her being fully involved in the first prank together.

No one said anything after she left until after they had walked to the portrait of the fruit bowl and Peter had tickled the pear.

The portrait swung open and Toby met them almost a once.

'Masters James, Sirius, Remus and Peter have returned!' Toby squealed.

'Hi Toby.' James said.

The others said similar things.

'Is there anything Toby can do for you?' Toby asked excitedly.

'Actually Toby-' Sirius started.

'Yes,' James cut Sirius off before he could order cake. 'Can you put a few drops of this potion in everyone's drinks tomorrow morning at breakfast?'

'Of course! What does the potion do?' Toby asked, taking the potion form James's hands and eyeing it carefully.

'It's a surprise. It doesn't hurt anyone or anything so don't worry. And we won't tell anyone you did it. Promise.' James said.

'Okay.' Toby agreed.

'Thanks Toby. We really must be going now! Bye!' James yelled over his shoulder as he dragged Sirius away from the cake he had ordered from another house elf and out of the kitchen.

Remus and Peter followed behind them, shaking their heads at their friends.

'It takes a few minutes to take effect.' Gracie whispered out of the corner of her mouth as she passed them on the way to her seat the next morning at breakfast.

She sat down near Mary and quickly took a drink and a few bites of her breakfast.

'Eat, or it'll look suspicious.' She mouthed.

They quickly did so.

Not even a minute later, they were singing songs they hadn't even heard of.
