Redwater

The woman in the Harlow jacket didn't move. She just looked at the three of them the way you look at a photograph you've carried for years — like she was checking whether they matched the memory.

"Close the door," she said.

Behind them, Okafor said, "I wouldn't," in the same voice he'd used to ask for extra napkins at the observatory picnic, eleven years of politeness wrapped around something cold. "Test starts in ninety seconds, key or no key. But do come in. You're making history."

Maya's sneakers were already wet. Water — real water, tunnel water — lapped at the doorframe, brown and fast. Somewhere above them, metal screamed: a gate cycling open.

Priya did the only useful thing. She grabbed Okafor's sleeve and hauled him inside, and Jonas slammed the steel door and threw the bolt. The lock clunked like a period at the end of a sentence.

"Sixty seconds now, probably," Okafor said, checking his watch with genuine regret. "You always did dramatize the timeline, Priya."

"You know our names," Jonas said.

"I know everyone's names, Jonas. I signed your science fair certificate in fourth grade." Okafor smiled at the older Maya. "Dr. Sharma. Three years in my department. Never took the good parking space. I always wondered when you'd tell them."

"I'm telling them now," future Maya said. Blood had dried dark on her cuff where she'd torn it forcing the service door, breaking in ahead of them. "Maya. Listen. I rode my own broadcast back. One trip, one way — I burned eleven years of carrier to stand in this room tonight, because the test got moved up and in my history you don't walk through that door for nine more years."

"That's insane," Jonas whispered.

"That's Daniel," Maya and her older self said together, and the room went very quiet, because Maya hadn't said the thought out loud — she'd only thought it, in the tunnel, listening to the key knock like a tiny clock against the attic box.

Future Maya's eyes shone. "You thought: time itself, counting. I remember thinking it. That's how I know you're really me and not—" she glanced at Okafor — "one of his."

Trust, decided in a single sentence. Maya's fingers tightened on the brass key.

"Thirty seconds," Priya said. She had her phone out, the telemetry page bleeding red. GATE 1: OPEN. GATE 2: OPEN. "Somebody talk fast."

"The reservoir was drained in 2031," future Maya said. "Harlow didn't steal the water. The town voted to drain it. A dam-safety scare, six months of flyers on every door, a vote nobody remembers voting in — and Harlow got an empty basin five miles wide. You know what they've been putting in it since?"

"Don't say bodies," Jonas said.

"Redwater. Coolant slurry, solvents, everything the plant can't legally pour anywhere. Fifteen years of it, pressurized under its own weight." Her voice cracked. "The 'pressure release test' opens every gate for ninety seconds. Ninety seconds of redwater through the lower town. It won't look like poison, Maya. It'll look like a dam failure. The town dies twice — once in the flood, and once in the mud that buries every sample, every record, every witness."

The pipes groaned. The floor trembled under their feet.

"Ten seconds," Priya said, "and I need the plan to include the part where the key does something, because right now it's a very nice paperweight."

Maya looked at the door's two holes — the keyhole, and the headphone jack. Daniel's note, yellowed on the frame: SHE MUST BE LISTENING WHEN YOU TURN IT.

"The lock wants the signal," Maya said. "The key turns while 3.33 is being received. But the loop's dead — you're here, not broadcasting."

"Play her," Jonas said suddenly. He was staring at Priya's phone. "The recording. The live one from the tunnel — the gasping one. It has the ghost. The lock can't tell live from recorded if the ghost is in it. Daniel built a timestamp lock, not a liveness detector."

Priya was already moving. She jammed her earbuds' plug into the door's jack, queued the recording — future Maya's shredded voice, eleven years out, gasping it's not water, it's not—

"Wait," Okafor said pleasantly.

Maya's hand stopped a centimeter from the key.

"You're wondering why I'm not stopping you." Okafor straightened his cuffs. "Dr. Sharma spent three years in my department and never once looked at the override command table. I reprogrammed it in 2029, Maya. Daniel's fail-safe broadcast now reads OPEN-ALL. Your grandfather's great override doesn't close the gates." He smiled. "It opens them."

The room tilted.

"He's lying," Jonas said, but his voice was thin.

"Am I?" Okafor gestured at the console. "Turn it and find out. That's the beautiful thing about Daniel's design. One turn. No confirmation. No undo."

Future Maya had gone white. "I didn't know. I swear on Daniel's grave, I didn't know — I came back to make sure you turned it—"

"Then don't," Maya said.

"But the timer—" Priya's telemetry screamed. GATE 3: OPEN. GATE 4: CYCLING. The ninety seconds had been a bluff; the gates were already moving on their own sequence. "The test is running whether we turn it or not! If the override opens them wider—"

"Or closes them," Jonas said desperately. "If he's lying, the override closes them and we win. If he's telling the truth, we flood the town ourselves. It's a coin flip with six thousand people on it."

Maya looked at her older self — blood on the cuff, Harlow jacket, eleven years of infiltrating a company that poisons towns, one impossible trip back — and at Okafor, calm as a man watching weather.

"How do we know?" she whispered.

And that's when the dead phone lit up.

Future Maya's phone — the one she'd held like a talisman, dark since she'd arrived — flared alive on the console. 3.33 MHz. Live. The speaker crackled, and a voice came through, shredded by static and by years:

"Maya. Don't let her turn the key. She's not—"

Priya was already on the spectrum, fingers flying, face draining. "Ghost," she breathed. "There's a ghost. But the pre-echo — it's longer. This isn't eleven years." She looked up. "This is twenty. Maybe more."

On the console, the phone crackled again: "—she's not me anymore. Don't let her—"

Maya's fingers were on the brass key. The key was already turning. She didn't know whose hand would stop it first — hers, or the woman wearing her face.
