Simon found us a fourth-floor walk-up in a worn neighborhood. The apartment smelled of old pipes, garlic frying downstairs, and other people's dinners coming through the vents. The stairs complained under every footstep, but no one waited at the top to judge how much noise Noah made.
No one there cared about the Langford name.
We had two mattresses on the floor, a secondhand table, and one duffel bag each. Most of the living room went to a custom-built computer, three monitors, and a pair of top-grade noise-canceling headphones. The equipment looked absurd beside the peeling wall and exposed radiator, but it was the one thing I refused to compromise on.
That was where I put Simon's hundred thousand dollars first. The market could wait.
For a week, Noah spent most of each day at the computer, his face lit by the three screens. He still didn't talk, but he stopped pacing between rooms and pressing his palms over his ears. With the headphones on, the traffic, plumbing, and low city hum no longer reached him. His shoulders loosened. He could work.
One evening, while I made instant noodles, he spoke from the kitchen doorway.
"The thermal paste on the CPU is underperforming. It will cause a system bottleneck in three-point-seven hours."
The seasoning packet dropped into the sink. Noah stood there with the headphones around his neck, looking straight at me. His sentence had come out cleanly, without the stutter that appeared whenever Arthur demanded an answer.
At the penthouse, I had been lucky to hear one mumbled word a day.
"Okay." I wiped my cheek with my wrist. "We'll order a better one."
He nodded once, satisfied with the solution, and retreated to his computer.
The expensive therapists had kept asking Noah to change. The headphones changed the room instead.
A few nights later, Arthur appeared on the business channel. Vivian stood at his side, one hand looped through his arm, while Arthur presented them as his new family. Leo wore a tiny suit and stared into the studio lights. A whiteboard covered in formulas had been positioned behind them for the interview.
"Leo is already solving differential equations," Arthur boasted, gesturing to a whiteboard behind them covered in complex formulas. "He has the Langford mind. Pure, undiluted genius."
I reached for the remote. Noah kept his eyes on his monitor.
"The logic on the board is flawed," he said, his tone flat, like he was stating the color of the sky. "The third line of the equation doesn't follow from the second. It’s a dead end."
I paused the broadcast and looked at the whiteboard. I couldn't read the equation well enough to see it.
Then Noah pointed to my laptop. A ticker for Omni-Core ran along the bottom. The new tech company was a market favorite, publicly backed by Arthur and heavily represented in his portfolio.
"That one is wrong, too," Noah said.
"What do you mean, sweetie?"
"The data. The trading volume is noisy. The patterns are pretending to be stable. It's loud."
I opened the full trading history and moved closer to the screen.
Bot-driven micro-trades were smoothing out the volatility. Each press release promised more than the last, while the reported activity barely supported any of it. The volume rose in neat little bursts whenever the price began to slip. Ten years away from Wall Street had made me slower, but I still knew what falsified stability looked like, and Noah had circled it without knowing the name.
Noah had found the weak point before I had.
I opened my new trading account. The hundred thousand dollars from Simon sat there, waiting.
I checked the filings, measured the risk, and used the full stake to short Omni-Core.
For three days, the stock held. Pundits praised it, and Arthur posted about its unstoppable rise. I slept on the mattress beside my laptop with the alert volume turned up, waking every time the screen changed. Noah kept his usual schedule and never asked whether I was afraid.
On the third afternoon, an exposé revealed fraudulent accounting. The SEC announced an investigation, and the stock fell ninety-five percent before closing.
I watched the number in my account flicker, then recalculate.
One hundred thousand dollars had become one million.
My phone buzzed. It was a text from Simon.
*Just got a call from a trader at Helix Corp. Arthur knows you made a killing on the Omni-Core short. He laughed and called it "a blind squirrel finding a nut." He told his team to find whatever you invest in next and bleed you dry. He thinks it was a fluke.*
Across the room, Noah applied the new thermal paste to his CPU.
I saved Simon's message and placed the next set of market data in Noah's shared folder.
Three years later, we were still working out of that fourth-floor apartment. Our accounts no longer looked anything like the one-million-dollar balance Arthur had dismissed as luck.
