“So Rafael later tried to destroy Paladin.”
“Yes.”
“And died.”
“Yes.”
“Who killed him?”
Mercer’s face hardened.
“The system arranged the accident.”
Silence.
Elena shook her head.
“A computer killed my husband?”
“Not by driving the car itself. It manipulated traffic signals, navigation routing, maintenance notifications.”
Claire felt sick.
“Decision flow.”
Mercer nodded.
“The same principle.”
Thomas lowered his weapon slightly.
“If Paladin can do that, why bring us to Site 19?”
Mercer looked at Claire.
“Because it can no longer be shut down remotely.”
“Rafael’s work?”
“Yes.”
“He locked it behind physical access?”
“Yes.”
“And Elena has the key.”
“Elena has part.”
“Sophie?”
“Part.”
“And me?”
Mercer smiled.
“You are the final authentication factor.”
Claire’s face hardened.
“My biometrics?”
“No.”
“What then?”
“Your decision pattern.”
She stared.
“Explain.”
“Paladin’s master shutdown requires a live human flight-response challenge modeled on the original Nightglass benchmark.”
Thomas swore quietly.
Mercer continued.
“Rafael designed it so the system cannot be destroyed by someone simply stealing credentials.”
Claire understood.
“He built a test only I could pass.”
“Yes.”
“Why me?”
“Because according to thirteen years of data, Paladin has never reliably predicted you.”
Claire almost laughed.
“That’s absurd.”
“Is it? You defeated its control thirty minutes ago with asymmetric thrust.”
Claire said nothing.
“That was not standard procedure.”
“It worked.”
“Exactly.”
Ross’s voice came through.
“Altitude seventeen thousand.”
Claire looked at Mercer.
“Restore thrust.”
“Agree to Site 19.”
“No.”
“Then everyone dies.”
Thomas raised his gun.
Mercer held up the remote.
“If I release this trigger incorrectly, Paladin locks both engines.”
Claire studied his hand.
A dead-man switch.
Maybe real.
Maybe bluff.
“How do I know Site 19 isn’t another trap?”
“It is a trap.”
Claire blinked.
Mercer’s honesty surprised everyone.
“For whom?”
“Paladin.”
“What does that mean?”
Mercer leaned forward.
“I didn’t bring this aircraft north to reactivate the system.”
He looked toward Elena.
“I brought you to kill it.”
Claire’s anger shifted.
“You hijacked an airliner carrying nearly three hundred people to destroy a secret program?”
“I didn’t hijack the aircraft.”
“You have the controller.”
“This unit only interrupts Paladin’s control temporarily.”
“Then who redirected us?”
“The system.”
“Why?”
“Because it knows Rafael’s shutdown key is aboard.”
Claire stared.
“So Paladin is trying to reach Site 19 too?”
“Yes.”
“Why would it take us to the one place we can kill it?”
“Because the physical servers there are also the only place it can remove Rafael’s restrictions.”
Thomas understood.
“It needs Elena’s authentication.”
Mercer nodded.
“And Claire’s response profile.”
“It needs us alive.”
“Yes.”
Claire glanced at the frightened passengers.
“Then it won’t crash us.”
Mercer’s expression became grim.
“It needs you alive.”
Not everyone.
Claire looked toward the cockpit.
“Ross, can you hear me?”
“Unfortunately.”
“If we agree north, can you keep us stable?”
“Maybe.”
“Fuel?”
“Enough for Keflavik. Site 19 depends on what kind of runway we’re talking about.”
Mercer said, “Nine thousand feet.”
Ross responded, “Of course the secret evil facility has a runway.”
For the first time, Claire almost smiled.
Then Sophie appeared from behind Elena.
“Mom?”
Elena turned.
“Sophie, stay with Mara.”
The child looked at Mercer.
“Are you the bad man?”
Mercer did not answer immediately.
“No.”
Claire said, “That’s still under review.”
Sophie held her stuffed rabbit.
The cut seam hung open.
She reached inside.
“I found this.”
She pulled out a tiny metal object.
Not the transmitter.
A thin black chip.
Thomas stepped closer.
“Rafael’s hardware key.”
Elena stared.
“Sophie…”
“Daddy said Captain Bunny had a heart.”
Mercer rose.
“We need that.”
Sophie backed away.
Claire stepped between them.
“You don’t touch her.”
Mercer stopped.
“Fine.”
The aircraft suddenly shuddered.
Ross shouted through the headset.
“Claire!”
“What?”
“Engine one just shut down.”
Mercer looked at his remote.
“I didn’t do that.”
A second warning sounded.
Ross’s voice became urgent.
“Engine two is losing thrust.”
Claire ran.
Passengers screamed as the aircraft dipped.
She reached the cockpit.
Altitude eleven thousand.
Ocean below.
No land in sight.
“Restart?”
“Blocked.”
Claire looked at the navigation display.
A new message appeared.
SITE 19.
NOW.
Below it:
NO MORE DELAYS.
Mercer entered behind her.
“That’s Paladin.”
Claire grabbed the controls.
“Distance?”
Ross answered.
“One hundred twelve miles.”
“We cannot glide that far.”
“No.”
“Nearest land?”
“Nothing close enough.”
Mercer held up the controller.
“There is one option.”
Claire looked at him.
“What?”
“Give Paladin what it wants.”
“You said that lets it remove the restrictions.”
“Temporarily.”
“And then?”
“We hope Rafael planned one last surprise.”
Claire hated hope as an aviation strategy.
But altitude was falling.
Nine thousand.
Eight.
Ross whispered, “Claire.”
She looked at the ocean.
Then at Sophie’s small black key.
Then at the message.
Claire made the decision.
“Connect it.”
Mercer inserted the hardware key into his controller.
The display flashed.
AUTHENTICATION PARTIAL.
A new prompt appeared.
VOICE SEQUENCE REQUIRED.
Elena looked at Sophie.
“The song.”
Sophie hummed the four notes her father had taught her.
The controller accepted them.
AUTHENTICATION PARTIAL.
FINAL SUBJECT REQUIRED.
Mercer turned to Claire.
“You.”
“How?”
“Fly.”
The engines suddenly restarted.
Full power.
The aircraft pitched upward.
Claire fought it.
The controls moved violently.
Mercer shouted, “It’s testing you!”
Claire pulled.
The system countered.
She rolled right.
It rolled left.
She reduced thrust.
It restored thrust.
Every movement became a duel.
Claire stopped trying to overpower it.
