The hammer rang once. A spark jumped off the anvil and did not go out. It waited. They followed.

It came on a Tuesday night in May, when Tara was supposed to be revising.

She had been staring at the same page of chemistry notes for twenty minutes. Her phone was face down on the desk, which was the rule she had made for herself during exams. It buzzed. She turned it over, because the rule was not a very good rule.

It was a message request from someone she did not follow. The name was Jordan, with a little lightning bolt after it. The picture was of a young man in a good jacket, smiling, leaning on a very shiny car.

Hey Tara! Hope you don't mind me messaging. Your cousin Zane said you might be interested in some quick work? No experience needed, totally flexible, 10 mins of your time. Let me know and I'll explain! 🙌

She did mind, a bit. But she was tired of chemistry. She tapped on his profile. He had nearly nine thousand followers. There were photographs of him at a beach, and in a restaurant, and holding up a box of trainers. The top post said Building my business one day at a time 💯.

She wrote back. Hi. What kind of work?

He replied almost at once, as if he had been waiting.

Easy. I run an online business and sometimes payments from customers need to go through a UK account before they get to my supplier. So £2,000 comes into your bank, you send £1,700 to the supplier, and you keep £300 for your time. Literally 10 mins on your banking app. Zane did one last month, ask him! 😊

Tara read it twice.

Three hundred pounds. For ten minutes.

She got out the folded plan from her bag. It was very soft now at the folds, nine months of pencil on it. At the top, underlined twice: £127.50 a month, every month, for the deposit. She had not missed a month. But April had been tight, because of the cottage, and she was a few pounds behind where she wanted to be.

Three hundred pounds was more than two months of the deposit. In ten minutes.

She felt a small, warm, fizzing feeling, the kind you get when something you have been worrying about suddenly looks easy.

Underneath it, very quietly, there was another feeling. She did not have a name for it yet.

"I was going to say yes," Tara said.

It was Wednesday, at the back table of the Whetstone café. She had brought her chemistry notes as a disguise. Danya was there, doing a jigsaw of a lighthouse that the café kept for children. Across from her sat Redline, who marked up everything she signed with a red pen, including permission slips for school trips, and who was never alarmed by anything.

"I was going to say it like this," said Tara, showing her the phone. "It's not my money. I'm not stealing anything. It just passes through my account and I keep a bit for helping. Zane did it last month and he was fine. Three hundred pounds is more than two months of my deposit. I'd be stupid to say no."

She had the reply half typed. OK I'm in! What do I need to do?

It felt good. It felt like a lucky break, in a year with not many.

Redline read the message slowly, the whole thread, from the lightning bolt to the smiling face.

"Never sign anything unread," said Redline calmly.

"There's nothing to sign," said Tara. "It's a message."

"Then read it out loud," said Redline. "And then tell me what you're agreeing to. In your own words. Not his."

Tara read it out loud. Payments from customers need to go through a UK account before they get to my supplier.

"Now in your own words," said Redline.

"I let him use my bank account," said Tara. "To move money."

"Whose money?"

"His customers'," said Tara. Then, more slowly, "I don't actually know whose."

"Where does it come from?"

"I don't know," said Tara.

"Where does it go?"

"To a supplier. I don't know who that is either."

"Say it all together," said Redline. "Calmly. In your own words."

Tara looked at the phone. "I let someone I've never met use my bank account to move two thousand pounds from somewhere I don't know to someone I don't know, and he pays me three hundred pounds for it."

It sounded different, out loud.

"Says who it's a bad thing?" said Danya, from the jigsaw. "Maybe it's just a business."

"Maybe," said Redline. "That one's ordinary. That one isn't. I can't tell which yet. Neither can you. That's the point."

"How do we know who Jordan is?" Danya asked.

Nobody knew. That was the problem.

Verify kept four tabs open for every claim and never fewer, and Verify did not like the phrase it's going round. Verify took Tara's phone without asking, which was rude, and began.

"Stop. Trace it first," said Verify. "Before you defend it, or answer it. Where did it first appear? Who is this person?"

Verify looked at Jordan's profile. Then Verify looked at it differently: not at the pictures, but at the dates.

"This account is three weeks old," said Verify. "All nine thousand followers, in three weeks. Look. The first post is the twenty-ninth of April."

Then Verify took the picture of Jordan leaning on the car, and searched for it.

It came up straight away. It was on a website that sold photographs for adverts. The same young man, the same jacket, the same car. Underneath it said Young businessman with sports car — stock image. Anybody could buy it.

"Going round isn't the same as true," said Verify. "And a face isn't the same as a person."

Danya had stopped doing the jigsaw.

Then Corah, who was at the next table and had been listening, leaned over.

"Wait," said Corah. "Is that Jordan with the lightning bolt?" She got out her own phone. "I got that. On Monday."

She showed them. It was the same message. Word for word. Hey! Hope you don't mind me messaging. Your cousin said you might be interested in some quick work? Except that Corah did not have a cousin called Zane. Corah's said your friend.

"Sanjay got it too," said Corah. "And Amira. I thought it was just me."

"Find the oldest copy," said Verify. "There isn't one. It's the same message, sent to everybody, by an account that didn't exist a month ago, with a face you can buy."

Tara looked at her phone. Zane did one last month, ask him!

The quiet feeling underneath had got louder. It had a name now, nearly.

Yusuf checked his own payslip with a calculator every month, and had once found a mistake in his favour of eleven pence and taken it back. He looked at the message for a long time.

"Gross is what you earn. Net is what you get," said Yusuf. "Read every line in between. That's what I do with a job. So let's do it with this one."

He took Tara's chemistry notebook and turned to a clean page.

"A real job has an employer," said Yusuf. "With a name, and an address, and a phone number that a person answers. Who's the employer here?"

"Jordan," said Tara. "Who isn't Jordan."

"A real job has a payslip," said Yusuf. "Your hours, your pay, tax taken off, your National Insurance. You get a piece of paper, every time. Is there a payslip?"

"No."

"Check the hours first," said Yusuf. "How long is the work?"

"Ten minutes."

"And the pay?"

"Three hundred pounds."

Yusuf wrote it down. £2,000 in. £1,700 out. £300 kept. Then underneath: £300 for 10 minutes.

"Do the sum yourself," said Yusuf. "Ten minutes is a sixth of an hour. So three hundred pounds for ten minutes is one thousand eight hundred pounds an hour."

Tara stared at the page.

"What do you get at the bakery?" said Yusuf.

"Eight pounds fifty."

"So this job pays more than two hundred times what the bakery pays you," said Yusuf. "For pressing a button on your banking app. Nobody in the world pays eighteen hundred pounds an hour for a bank transfer. Banks do transfers for free."

"So what's he paying for?" said Danya.

"Which line took that?" said Yusuf. "That's what I always ask. Here it's easy. He's not paying for your ten minutes. He's paying for your account. Your name. A real person's real bank account, with a real history, that the bank trusts. That's what's worth three hundred pounds to him."

"Hm," said Tara.

Devon answered almost every offer of anything with a question about Sundays. He sat down at the end of the table and read Yusuf's page, and then the message, and then the page again.

"What does it cost you?" said Devon. "Not in money."

"It doesn't cost me anything," said Tara. "That's the whole point. I get three hundred."

"Every yes is a no to something," said Devon. "Say what you'd be swapping."

He drew a line down the middle of a napkin. On one side he wrote what you get. On the other side, what you give.

Under what you get he wrote £300. "That's about two and a third months of your deposit," he said. "That's real. I'm not pretending it isn't. Three hundred pounds is a lot of Saturdays."

Under what you give, he wrote slowly.

"The two thousand pounds has to come from somewhere," said Devon. "If it were ordinary money, from an ordinary business, he'd use an ordinary bank account. So it's probably somebody's money that was taken from them. Somebody who's going to report it missing, and the bank will trace where it went." He wrote someone else's money. "And where it went is your account. Every transfer, in your name, from your account, on your phone."

He wrote your name.

"And if the bank thinks your account was used to move stolen money," said Devon, "they can close it. And it's not easy to get another one, when you're about to move away and need one for rent." He wrote your account. "And the police can see it as a crime, even if you didn't know where the money came from. That's the bit that people think doesn't apply to them."

Tara looked at the napkin. On one side, three hundred pounds. On the other side, a list.

"Not in money," said Devon. "In everything else."

"Let me listen first," Tara said, mostly to herself.

She took Yusuf's page and wrote three headings across the bottom: what it says, what it is, who else is in it.

Under the first she wrote quick work, £300, 10 mins, Zane did it. Under the second, someone pays £1,800 an hour to use my account; account 3 weeks old; photo bought. The third column took longer: whoever the £2,000 belongs to, then Corah, Sanjay, Amira, and then, after a pause, Zane.

"I think we missed someone," Tara said slowly. "Zane. He's already done it. Twice, maybe. His name's already on it."

Nobody said anything for a moment.

Then her phone rang. It was Zane.

She took it outside, onto the bench by the café door. Danya came too, without being asked, and sat at the other end.

"Did Jordan message you?" said Zane. He sounded cheerful, the way he always did. "He's sound. Honestly. I did one last month and another one on Saturday. Six hundred quid, Tara. For like twenty minutes. Mum's been short since the hours at the warehouse got cut, and I gave her half, and she cried. Nothing's happened. Nobody's rung me. I'm not robbing anyone. I'm just moving it." He laughed. "And he asked if you had any mates who wanted work. I said you might. You'd get a bonus for every one."

It was the strongest version of everything, and Zane believed every word. He was not stupid, and he was not greedy. He was seventeen, and his mum had cried.

While he was talking, a text came in from Tara's mum.

Hope revision's going ok love. I know money's tight this year. You know I trust you. I'd rather you did an extra Saturday than anything silly though x

Her mum was not wrong either.

And Jordan's message was still there, at the top of her phone, friendly, patient, never pushy.

No pressure at all Tara! Lots of people want this work so let me know by tonight if you're in 😊🙌

"Tara?" said Zane, on the phone. "You still there? Are you in?"

On the bench beside her was Danya, very still, not doing anything. In her bag was the folded plan, with £127.50 a month at the top and nine months of pencil under it. On her phone was a smiling face from a picture library, three weeks old. In the café behind her, on a napkin, were two columns: £300 on one side, and someone else's money, your name, your account on the other. And on the phone, waiting, was her cousin, who had given half of it to his mum.

"Tara?" said Zane.

 

 

(Write what Tara says to Zane.)

 

The spark dimmed to a warm dot and settled back on the anvil. The Green was just the Green again.

Back on the Green

That evening Lan, who was seven, came home with a sticker book. A girl at the park had given it to her for nothing, if Lan would let the girl's big brother borrow Lan's bike for the afternoon.

Danya asked her where the bike was now.

Lan said the big brother had it. She did not know where he had taken it. She said she did not know his name.

They went to the park together. The bike was by the gate, lying on its side, with the chain off. Lan's dad fixed it.

Lan said she would keep the sticker book. She said she would not lend the bike to anybody whose name she didn't know, ever again, even for stickers.

Afterword. The idea in this case is a money mule: someone who lets their bank account be used to move money for another person, often money from crime, keeping a small part for themselves. Mules are often recruited online, by friendly messages that look like ordinary job offers, and young people are often asked, sometimes through friends or family who have already said yes. The warning signs are the ones in the case: a stranger, an account that is new, a face that may not be real, the same message sent to many people, and pay that is far too high for the work. A job that pays you for the use of your bank account is not paying you for work; it is paying for your name. If you have been asked, or if you have already done it, tell your bank and a trusted adult straight away; telling early is always better than waiting. You can practise tracing where a message came from in NewsForge, and reading what a job really pays in LedgerQuest.
