The common room was loud. Not in the fun way, but in that irritating, unfocused Slytherin way that made me crave silence and a locked door. First-years were arguing about cauldron sizes. A third-year was loudly reading a love letter that was clearly not meant for them. And someone had spilled a vial of Sleekeazy's on the rug, which now shimmered with suspicious green mist.
I closed my book. There was no point pretending I could focus.
Tracey plopped down beside me, grinning with chocolate on her chin.
"Did you know Zonko's stopped selling the color-changing toffee?" she said. "Total outrage. I had to threaten a fourth-year just to get the last piece."
My eyebrow lifted. "Threaten them with what?"
"My smile," she said sweetly. "It's terrifying when I mean it."
I gave her a faint smirk, but something caught in my mind. A moment of connection.
No Zonko's. Shortage.
Shortages meant opportunity.
I stood abruptly, brushing imaginary dust from my skirt.
"Where are you going?" Tracey asked.
"To speak with Timothy," I said.
"About toffee?"
I did not answer.
…
The Great Hall buzzed with whispers, rustling parchment, and the faint clink of silverware. But I was not here for gossip or toast. My eyes scanned the long Slytherin table until they landed on the source of unnecessary drama and absurd brilliance.
Timothy Rosier.
Lounging like he owned the table, one leg crossed over the other, sipping what could only be iced coffee from a conjured glass. Of course. No one in Hogwarts drinks iced coffee except him, and only because he showed the house-elves how to make it.
He was reading The Daily Prophet like it was poetry. A slight smile tugged at the corners of his mouth. I didn't need to see the headline to know what it said.
Sirius Black. Officially cleared. Publicly freed.
The Ministry was in shambles over it, and Skeeter had torn into them with enough venom to give Snape competition. Black was currently in Saint Mungo's under heavy potion therapy and emotional restoration after years of Dementor exposure.
And Harry? He had been writing him almost daily. Good. He deserved that kind of closure. That kind of truth.
I stood just behind Timothy, hands folded neatly in front of me. I waited. He did not look up.
Typical.
"Timothy."
He took another slow sip of his coffee, not reacting.
I resisted the urge to roll my eyes.
"I know you heard me," I said. "I need your... assistance."
The delay was deliberate. He folded the newspaper, finally turning his face toward me with that infuriatingly theatrical smile.
"My dear friend Daphne," he said, tone like silk wrapped in sarcasm. "How may this humble peasant be of service to a lady of such... refined ambition?"
I exhaled through my nose. Calm. Steady. Do not hex him in public.
"You have a trunk full of questionable goods, a working knowledge of loopholes, and no current scandal to entertain you," I said. "I have a plan, a structure, and a need for inventory. Let us skip the part where you act surprised."
He set down his glass with a clink, eyes glittering with interest now.
"I'm listening," he said.
"I'm building something. Quietly. Carefully. A student-based exchange system. Needs, wants, and favors. You'll provide the supply, I'll handle the rest."
His brows rose, delighted. "Are we finally committing crimes together?"
I tilted my head. "I am committing opportunity. Whether you classify that as crime or commerce is your business."
He laughed softly, pushed the folded Prophet aside, and gestured to the seat beside him.
"Let's begin then. Over iced coffee, naturally."
…
Timothy's trunk was more impressive than I expected.
I ignored the chair he gestured to and walked straight to the trunk he had cracked open. I peered inside.
It was chaos. Organized chaos, but chaos nonetheless. Rows of labeled boxes. Wrapped packages. Bottles. Muggle sweets. Shiny imported journals. A copy of Witch Weekly with a French sticker on the front. Beauty products I had not seen since summer in Paris.
I looked back at him.
"Explain."
He shrugged. "Some things I bought. Some things I found. Some things might have simply wanted to be found."
I gave him a long look.
"You want to be vague. Fine. But I know an opportunity when I see it."
He tilted his head slightly. "And what opportunity do you see?"
"A school full of underfed, undersupplied, hormonally charged teenagers," I said. "And an unregulated supply line."
His smile widened. "You want to start a black market."
I returned the smile, just slightly. "I want to start an exchange."
He closed the notebook and leaned back in his chair.
"I will provide the goods," he said. "You manage the clientele."
"I choose my couriers. I set the prices."
"I reserve the right to veto dangerous requests."
"I already vetoed you giving Blaise anything sharp," I said.
We stared at each other for a long beat, then shook hands.
I could feel the shift in the air already.
Not power exactly. Not yet.
But the beginning of something sharper.
Something silk-wrapped and coiled like a snake in the dark.
<><><><><><><>
Business was, how Timothy would put it, booming.
Our products had become the talk of the school, a currency of status and indulgence. Even Professor Lockhart had discreetly requested a few beauty supplies, delivered in a gold-trimmed box with no return address.
My couriers were exactly as I trained them to be—professional, punctual, and silent. Their motivation? Early access and generous discounts on the most coveted items. Nothing inspires loyalty like power wrapped in privilege.
The first sign something was wrong came when my first-year courier arrived empty-handed.
He stood outside the library, shifting his weight awkwardly as I watched him from the alcove near the stairwell. I had sent him to deliver a discreet package of enchanted lip glosses and a heatless curling charm to a fourth-year Ravenclaw. The kind of small indulgence that had made the Exchange popular without drawing too much attention.
But now he was fidgeting. Nervous.
"I swear I had it," he blurted the moment I stepped into view. "But she said she already got the same thing. From someone else."
My jaw tightened.
"Who?" I asked. I kept my tone level. Cool. But my stomach twisted.
He shrugged helplessly. "She said... the Twins."
Of course.
Fred and George Weasley. The redheaded prank lords of Gryffindor. Their fingerprints had been all over the castle since first year, but they had never interfered with my business before. Likely because it had been too small, too quiet. Too elegant.
Not anymore.
Two days later, it got worse.
My runners started returning with coins still in hand. Clients were backing out. Prices were being matched — no, undercut — and my inventory was losing its exclusivity. The final insult came when I visited the Astronomy Tower to oversee a special drop.
A group of third-years were already there.
Laughing. Unwrapping brightly colored toffees that sparkled with cinnamon-sugar magic.
I stepped forward.
"Where did you get those?" I asked.
One of them blinked up at me. "The Weasley Wagon."
I blinked. "The what?"
They pointed toward the corridor. "Pop-up cart. Shows up in different parts of the castle. Only stays for ten minutes. Limited stock. It's genius."
I walked away before I hexed a child.
That evening, I found Timothy alone in our usual meeting room.
He was playing a low, dissonant tune on the enchanted piano he had pulled from Merlin-only-knows-where. It echoed through the dimly lit space like a heartbeat underwater.
I did not wait for him to finish.
"They are copying our products, spoofing our delivery times, and charming half the school with novelty names," I said. "And now they have a mobile cart."
Timothy did not look up.
"Charming," he said. "I always did enjoy capitalism in a castle."
"This isn't charming," I snapped, pacing now. "This is sabotage. I cannot build a network if they're burning my foundation with every prank and peppermint."
He lifted one hand, lazily playing a chord. "Then adapt. You are not out of moves, Daphne. You're just no longer playing alone."
I stopped pacing.
He turned toward me, fingers still idling on the keys. "They are loud. You are quiet. They want laughter. You offer leverage. Stop playing their game."
My eyes narrowed. "So what do I do? Burn their cart to ashes?"
He gave me a slow, satisfied smile.
"No," he said. "You beat them at their own show. Elegantly."
<><><><><><><>
The Weasley twins wanted a show. They wanted laughter, flash, chaos.
I would give them silence, efficiency, and results.
They may have painted a cart in Gryffindor colors and danced through the halls like circus kings, but I had something they did not.
Friends who knew how to listen.
…
I met Tracey in the back corner of the Charms classroom, late evening. She was seated on top of a desk, legs swinging, wand twirling between her fingers. She grinned when she saw me but it faded when she saw my face.
"Time to take off the gloves?" she asked.
"Not gloves," I said. "Veil."
I handed her a small parchment. It contained five names. Known customers of the Twins' "Weasley Wagon." Students who thought prank powder and mood toffees were peak innovation.
"I need you to follow them," I said. "Casually. Make note of where the cart appears and who they talk to. Do not get caught."
Tracey gave me a mock salute. "Subtle chaos. I'm in."
…
Blaise was more reluctant.
He leaned against a pillar in the courtyard with a half-eaten apple in one hand and an expression that said he had more interesting things to do.
"Tell me why I should help you win a pissing match with the Weasley dynasty," he said.
"Because you dislike losing," I replied. "And because I will owe you a favor."
He considered that.
"Fine," he said. "What do you want?"
"I need you to offer them a deal," I said. "A decoy client. Someone desperate for bulk. Say you represent a buyer. Give them a fake name. Offer a price just high enough to tempt them."
He arched a brow. "And?"
"When they accept, they will tie up their entire next restock preparing it. While they wait for a buyer who never appears, we flood their usual route with my best products. Limited edition. Half price. Spell-enhanced."
He laughed, biting into his apple. "You are colder than the lake in January."
"I am thorough," I said.
…
The next step was Luna.
I found her in the greenhouses talking to a cactus that was blinking too much. She greeted me like I was part of the weather.
"Would you like to help shift the balance of power in the student market?" I asked.
She tilted her head. "Only if I can wear bells."
"I will allow bells."
Her job was simple. Walk the corridors the Twins usually frequented. Do not say anything directly. Just drift by and whisper to herself that "better things are coming." Carry one of my custom-wrapped packages. Let the rumor do the work.
She agreed on the condition that I give her first pick of our next shipment of enchanted glitter.
Done.
…
Three days later, the castle rippled with whispers.
The Weasley cart was nowhere to be seen by midweek. Tracey confirmed their buyers were confused. Blaise's false client had sent them scrambling for resources. And Luna had created just enough mystery that my couriers were met with curiosity instead of hesitation.
That afternoon, I rolled out my answer to their chaos.
The Silk Case.
Elegant. Discreet. A conjured black-and-silver cabinet with compartments that unfolded when touched with a specific code word.
Inside? Enchanted perfume. Lip charms that shifted color with mood. Muggle-style pens with invisible ink. Hair dye strips that changed daily. Every item branded with a small green ribbon seal.
Tracey worked the left corridor. Blaise stood nearby looking bored but alert. Luna floated through the upper level singing faintly about velvet truths and sugar lies.
We sold out in ninety minutes.
The difference was control. No rush, no chaos. Just a whisper, a name, and a case that opened for the right person. No one had to chase our product. It came to them.
…
I was in the music room later that evening, reviewing our coin count, when the door opened.
Fred and George stepped inside together.
George gave a low whistle. "We heard you started painting the halls with ambition."
Fred grinned. "Thought we'd congratulate the new queen of contraband."
I did not rise from the piano bench. I looked at them over my shoulder.
"No hard feelings?" I asked.
"None," George said. "You hit us clean. No hexes. No stink bombs. Just clever moves."
Fred nodded. "That thing with the buyer? Brutal."
I closed the coin pouch beside me.
"Thank you. If you want to make an offer, I am willing to discuss territory lines."
They looked at each other.
George smirked. "You ever consider partnering with people who specialize in spectacle?"
"I specialize in silence," I said. "But I take meetings."
They bowed low, overly dramatic, and left laughing.
As the door clicked shut, I leaned back against the piano.
Timothy would be pleased.
I did not burn their cart.
I claimed their customers.
And they thanked me for it.
