Chapter 4 - FIONA’S WARNINGFiona did not leave the hospital.

Security found her inside a locked specimen-preparation room holding Toby’s missing blood tubes against her chest.
She raised both hands when Detective Cole entered.
“I did not steal them.”
“You removed sealed evidence.”
“I replaced it before Malcolm destroyed it.”
Dr. Vane stood behind the officers.
“That woman is experiencing a psychiatric episode.”
Fiona looked directly at Naomi.
“Check the seals.”
Naomi examined the tubes.
The evidence numbers matched, but the rubber caps carried tiny puncture marks. Someone had already inserted a needle into each tube before Fiona reached the laboratory.
“The samples were contaminated,” Fiona said.
“With what?” Cole asked.
“A compound that would make ARX-417 appear harmless.”
Vane’s voice sharpened.
“She is lying to protect her company.”
Fiona laughed without humor.
“You have billed my company for illegal pediatric monitoring for four years.”
Elijah stared at his sister.
“You knew about Toby?”
“I knew a child existed under the T-4 code. I did not know it was him until six weeks ago.”
“Why didn’t you tell me?”
“Because Malcolm sent me photographs of your son sleeping.”
The threat had begun when Fiona discovered ARX-417 leaving the company’s restricted laboratory.
She traced the shipments to Cassandra’s address.
Before she could confront Elijah, someone accessed her voice profile and began calling Cassandra through a cloned laboratory extension.
“I never prescribed that bottle,” Fiona said.
Cassandra’s face twisted.
“You met me at the hotel.”
Fiona shook her head.
“A woman wearing your company badge gave me the first vial.”
“Did you see her face?”
“She looked like Fiona.”
Fiona removed her identification card.
The photograph had recently been replaced in the corporate system. Her face could be copied. Her fingerprints could be duplicated from laboratory scanners. Her voice existed in thousands of recorded meetings.
Someone had built a complete working version of her identity.
Naomi asked the question no one else had considered.
“Why would the impostor need Cassandra to believe Fiona supplied the medicine?”
“To make the evidence lead toward Mercer Biodynamics,” Cole replied.
Fiona nodded.
“And away from whoever modified the formula inside this hospital.”
She opened a secure file on her tablet.
ARX-417 had two components. Mercer produced the inactive base molecule. A second activator had to be added shortly before administration.
The activator found in Toby’s blood was manufactured by Harborview’s experimental pharmacology unit.
Dr. Vane controlled that unit.
Vane turned toward the officers.
“This is a corporate attempt to discredit a hospital investigation.”
Fiona sent the documents to Detective Cole before Vane could order the network disconnected.
Elijah looked at his sister.
“You knew Project ARX continued.”
“I knew the company preserved the files.”
“You became laboratory director.”
“I thought holding the position would let me find who kept using them.”
“You protected the company.”
“Yes.”
“You protected the patent.”
Fiona’s silence answered.
She wanted to expose Vane without destroying Mercer Biodynamics.
The company employed thousands of people and produced legitimate medications. Fiona convinced herself she could isolate the criminal research, preserve the valuable work, and avoid public collapse.
Naomi had heard that logic before.
“Every person who hides this experiment says they are protecting something larger than the child,” she said.
Fiona lowered her eyes.
“Yes.”
Toby’s monitor alarmed in the trauma room.
They ran back.
His blood pressure was dropping again.
The compound in his body had entered a second phase.
Naomi needed the complete activator formula to treat him.
Vane claimed no such formula existed.
Fiona opened a Mercer file containing the original ARX design.
The second phase could be reversed only by a personalized antidote built from the child’s donor profile.
Toby’s donor cells came from Micah and Naomi.
The antidote required a fresh blood sample from Naomi.
She rolled up her sleeve immediately.
Vane stepped between her and the nurse.
“You cannot authorize an experimental transfusion.”
Naomi looked toward Toby.
“I am authorizing a medically necessary rescue treatment.”
“It may kill him.”
“Doing nothing will.”
Vane leaned closer and whispered so only she could hear:
“If Toby survives, the next child becomes unnecessary.”
Naomi stared at him.
“What next child?”
Vane’s expression changed.
He had revealed too much.
Then Toby opened his eyes.

“The girl,” he whispered. “They gave her the other dose.”
👉 Toby’s “other dose” belonged to a hidden girl connected to the same experiment—and Dr. Vane feared Toby’s survival would expose her.
