Chapter 3 - The Missing Calibration
The storage room was empty.
But the cabinet containing Piper's original exoskeleton parts was open.
One drawer had been pulled out.
Its contents were gone.
Vivienne's security director searched the room while Boone examined the electronic lock.
"No forced entry."
The badge reader showed Martin's credentials.
Yet the hallway cameras showed no one entering.
That meant either the camera feed had been manipulated or Martin's badge had been copied.
Piper remained in her wheelchair at the doorway.
She stared at the empty drawer.
"What was kept there?"
Dr. Warren answered quietly.
"Original components removed during fitting."
"Including spacers?"
"Yes."
Boone looked back at Piper.
Someone had taken the very parts that could prove what belonged in her machine.
Vivienne ordered the penthouse locked down.
Every staff member was interviewed.
Every access record was copied.
Nobody found Martin.
By midnight, Piper was exhausted.
Boone prepared to leave.
She stopped him.
"Will you come back tomorrow?"
He looked surprised.
"You've got engineers now."
"They didn't hear the click."
That landed harder than she intended.
Boone glanced toward Vivienne.
Her mother nodded.
"Come back."
Boone returned the next morning.
He brought no expensive diagnostic equipment.
Just his battered toolbox.
Dr. Cho had spent the night reviewing Piper's exoskeleton data. She had discovered something important.
The right-knee torque limit had been changed repeatedly.
Always slightly.
Never enough to trigger an automatic safety fault.
But over months, the adjustments had created a pattern.
Whenever Piper's gait improved, the right side was recalibrated within days.
Then her performance declined.
Piper stared at the graph.
"So every time I got better..."
Dr. Cho nodded slowly.
"The settings changed."
Vivienne looked sick.
Boone asked the obvious question.
"Who benefited from keeping her in therapy?"
Silence.
Dr. Warren's eyes filled with anger.
"The rehabilitation contract."
Vivienne turned.
"What about it?"
"The vendor receives monthly support fees."
"How much?"
Dr. Warren hesitated.
"Approximately forty-eight thousand dollars."
Boone whistled softly.
"Per month?"
"Yes."
Piper stared at her mother.
Vivienne had never mentioned it.
Perhaps because to Vivienne Larkin, forty-eight thousand dollars was an expense.
To Boone Halloway, it was probably a year.
But money alone did not prove sabotage.
Vivienne called the vendor's CEO.
Within an hour, attorneys were involved.
By noon, corporate representatives insisted Martin Voss had acted outside company procedure.
They also claimed his employment records had been suspended that morning.
Boone laughed when he heard that.
"They're cutting him loose."
Vivienne agreed.
"But why?"
"Because either he did something they don't want connected to them..."
Boone looked at the missing calibration graph.
"...or he knows who did."
Piper spent the afternoon undergoing imaging.
The results brought the first good news she had received in months.
There was inflammation.
There was muscle weakness.
There was strain from compensating for the misalignment.
But there was no evidence that the machine had permanently destroyed her ability to recover.
Piper cried.
Not dramatically.
She simply sat in the examination room and let tears fall.
Vivienne sat beside her.
Neither spoke.
For eleven months, Piper had been told to fight harder.
Now someone was finally telling her the fight might not have been fair.
That changed everything.
Dr. Cho recommended stopping use of the exoskeleton until it could be restored to verified specifications.
Piper agreed.
She returned to basic therapy.
Parallel bars.
Supported standing.
Simple weight shifts.
No motors.
No clicking.
The first time she bent her right knee without the machine, she expected the familiar resistance.
It did not come.
Pain remained.
Weakness remained.
Fear remained.
But the invisible mechanical hand pushing against her was gone.
Boone watched from across the room.
Piper managed one assisted step.
Then another.
She looked at him.
"Did you see that?"
"I did."
"Was it terrible?"
"Pretty terrible."
She laughed.
It was the first real laugh Vivienne had heard from her daughter in months.
Boone smiled.
"But the second one was less terrible."
Piper took a third.
Her leg trembled.
She stopped before exhausting herself.
For once, stopping did not feel like failure.
Later, Boone returned to his shop.
Vivienne had offered to pay him an extraordinary consulting fee.
He refused most of it.
"I fixed a lift and listened to a hinge."
"You may have changed my daughter's life."
"I pointed at a noise."
"You also stayed."
Boone's expression changed.
He accepted enough to cover his time and nothing more.
Vivienne did not understand him.
That made her trust him more.
At his shop, Boone placed photographs of the modified spacer beside images Dr. Cho had sent of the correct factory components.
Something bothered him.
The hand-ground edge was crude.
Martin was a trained technician.
Why would a skilled technician modify a precision part so badly?
Boone enlarged the photograph.
Then he saw it.
A second set of marks.
Not grinding.
Tool-jaw impressions.
Someone had clamped the spacer in a vise.
Boone knew that vise pattern.
His stomach tightened.
Years earlier, his father had owned an unusual set of serrated vise jaws made by a small industrial supplier.
After his father died, Boone inherited the tools.
He walked across his shop.
Opened a drawer.
Pulled out the old jaws.
The pattern matched.
Impossible.
Boone called Vivienne.
"I need to ask where Martin had the machine serviced."
"Here, mostly."
"Anywhere else?"
A pause.
"Once. Three months ago. The transport van broke down while carrying the equipment."
Boone froze.
"Where?"
Vivienne checked.
"Halloway Industrial Repair."
Boone stopped breathing.
"That's my shop."
He remembered the van.
A biomedical equipment transporter had arrived near closing time.
The driver said he needed a bracket straightened.
Boone had been away towing a stranded customer.
His former employee, Ray Mercer, handled the job.
Ray had left two weeks later.
Boone had thought nothing of it.
Until now.
He pulled the old invoice.
The customer name had been abbreviated.
M.V. Technical Services.
Martin Voss.
Boone called Ray.
The number was disconnected.
He searched old payroll records.
Ray's emergency contact listed an address across town.
Boone drove there.
The apartment was empty.
A neighbor said Ray had moved suddenly two months earlier.
"Did he say where?"
"No."
"Did anyone visit him?"
The neighbor thought.
"Some guy in a fancy company car came around a few times."
"Could you describe him?"
"Middle-aged. Neat. Silver badge."
Martin.
Boone returned to his truck.
His phone rang.
Piper.
"My mother said you found something."
"Maybe."
"What?"
He told her about the shop.
She went quiet.
"So the part could have been modified there?"
"Yes."
"By your employee?"
"Former employee."
"Did you know?"
"No."
"I know."
The certainty in her voice surprised him.
"How?"
"Because you heard the click."
Boone looked through his windshield.
Piper continued.
"Everyone who knew what that machine was supposed to sound like ignored it. You didn't even know what it was, and you stopped."
Boone did not know what to say.
Then another call appeared.
Unknown number.
He answered.
A distorted voice spoke.
"Stop looking into the Larkin machine."
Boone sat upright.
"Who is this?"
"You already found enough."
"Ray?"
Silence.
Then:
"Ask the billionaire what happened to the first rehabilitation company."
The call ended.
Boone immediately phoned Vivienne.
She did not answer.
He tried Piper.
No answer.
He drove toward the penthouse.
At the same moment, Piper sat alone in her room upstairs, staring at an envelope someone had slid beneath her door.
There was no name on it.
Inside was a photograph.
It showed Piper standing in the exoskeleton months earlier.
Behind her, reflected in the glass, stood Martin Voss.
And beside him was Vivienne.
On the back, someone had written five words:
YOUR MOTHER KNEW BEFORE YOU DID.
May you like
Piper heard footsteps outside.
The handle began to turn.
