Chapter 16 - THE HEARTBEAT ON TWO SCREENSThe two newborns did not share one heartbeat.
They shared one signal.
Dana Whitaker ordered technicians to disconnect every neonatal monitor from the DeLuca network. Dr. Nora Gaines switched the infant in Evelyn’s arms to independently verified equipment while federal agents entered the abandoned laboratory through three separate routes.
The second screen went dark.
Then returned with a different rhythm.
One hundred forty-eight beats per minute in Evelyn’s room.
One hundred thirty-six inside the laboratory elevator.
Bianca had copied the first baby’s monitor data and transmitted it beside the second child.
She wanted the family to believe the infants were biologically synchronized.
She wanted urgency to replace careful examination.
“Where is Matthew going?” Vittorio demanded.
The laboratory’s elevator descended rather than rising toward the street. Architectural records showed no lower floor.
Dana found the answer inside Isabella’s original fertility ledger.
The abandoned facility connected to a private railway tunnel built decades earlier for transporting research materials between DeLuca Biomedical properties.
Matthew had not entered an ordinary elevator.
He had entered an underground transport car.
Federal agents shut down power at both ends of the tunnel. Emergency brakes engaged automatically.
The car stopped beneath a wooded section of the DeLuca estate.
Matthew remained inside with the infant.
He held no weapon.
Only Grant’s wedding ring, a portable incubator, and a sealed envelope marked:
E-4—SECOND LIVING RESULT.
“Open the door,” an agent ordered through the intercom.
“Bianca controls the incubator remotely.”
“Then step away while technicians isolate it.”
“She said the child will stop breathing if the signal is lost.”
Dr. Gaines listened from the hospital.
“That is probably another control mechanism, but no one will test the claim on a newborn. Keep the local power stable. Disconnect only the outside communication.”
The technicians did exactly that.
The incubator continued functioning.
No alarm sounded.
Matthew looked toward the child.
Bianca had taught every participant the same lesson: only she understood which hidden danger would become real.
Once independent specialists examined the machine, her authority disappeared.
Matthew opened the transport-car door.
He surrendered the infant without resistance.
His face resembled Grant’s more closely than old photographs suggested because he had undergone reconstructive surgery after the mountain accident. The accident had been real. His death had not.
Isabella and Bianca found him injured before public rescue teams reached the mountain. Matthew had discovered records connecting Vale Reproductive Institute to his employer and carried copies during the climb.
Bianca offered medical treatment if he disappeared.
Isabella believed a legally dead witness could investigate the institute without being followed.
Matthew agreed for six months.
Then six months became eleven years.
“I thought I was exposing them,” he said after his arrest.
“You entered the laboratory with a hidden infant,” Dana replied.
“I was taking her away from Bianca.”
“You used your brother’s stolen ring.”
“It opened the Mercer authorization route.”
“You did not call police.”
“I did not know which officers were connected to Vale.”
“You knew Dana’s compliance team had secured the hospital.”
“I believed Bianca would kill the baby before they arrived.”
Again, an adult described secrecy as the only safe option after safer routes became visible.
The second infant entered independent neonatal care under the temporary designation Infant Two.
No DeLuca, Mercer, Voss, or Moretti surname appeared.
A postpartum patient was found inside the laboratory’s recovery wing.
Her name was Sofia Reyes.
She had been told she was carrying an embryo for an anonymous family through a lawful compensated-surrogacy program. Three days earlier, she delivered a girl.
Bianca’s staff showed Sofia an empty bassinet and told her the baby had suffered respiratory failure.
Sofia had heard the infant crying in the corridor.
When she attempted to leave her bed, she was sedated.
“They said the intended mother did not want me to see her,” Sofia whispered.
“Did you choose a name during pregnancy?” the advocate asked.
“I called her Iris when we were alone.”
The hospital used Iris as a temporary personal name while preserving Infant Two as the neutral evidence designation.
Sofia did not request immediate custody.
“I need to understand whose pregnancy they made me carry before anyone asks me to become someone’s mother.”
The decision was respected.
Independent laboratories collected samples from both infants, Evelyn, Eva, Bianca’s preserved medical materials, Isabella, Vittorio, Grant, Matthew, Sofia, and the remaining donor archives.
The tests were performed through multiple facilities using separate chain-of-custody teams.
No historical profile was accepted without physical verification.
The first result answered why Evelyn’s child appeared related to Matthew.
Matthew was the biological father.
Not Grant.
The egg belonged to Evelyn.
It had been created from the ovarian tissue stolen during her false appendectomy at fourteen.
Evelyn closed her eyes.
She was the infant’s genetic mother and gestational mother.
That did not make the conception consensual.
Her child had been created from tissue taken while she was a minor and sperm Matthew originally provided for limited fertility preservation at Vale’s institute.
Neither had authorized this embryo.
Grant had ordered B-19.
Lydia intercepted the carrier.
Eva believed she substituted an embryo created from her own tissue.
She had been deceived too.
The E-4 container placed inside Evelyn carried Evelyn’s egg, not Eva’s.
A second embryo had been implanted during the same procedure.
It was I-7—the preserved embryo created years earlier from Isabella and Vittorio.
That embryo stopped developing during the first trimester.
Its placental cells remained, distorting early DNA results and activating Isabella’s audit clause when Evelyn delivered.
The child in Evelyn’s arms had never been Isabella’s embryo.
The vanished pregnancy had been.
The second infant’s report arrived next.
Iris’s genetic mother was Eva.
Her biological father was an unrelated research donor named Julian Hart, whose sample had been authorized only for a discontinued fertility study. He had never consented to reproduction.
Bianca had created two E-4 embryos.
One from Evelyn.
One from Eva.
Then she allowed every conspirator to believe there was only one.
Eva stared at Iris through the secure video.
“She is mine.”
Nora answered carefully.
“She is genetically connected to you. Sofia carried and delivered her. Those facts matter. Neither gives you immediate possession.”
“I created the substitution to bring her into the DeLuca family.”
“You changed Evelyn’s medication and entered the neonatal room using a cloned badge.”
“I was trying to expose Bianca.”
“You endangered a mother and newborn while trying to expose her.”
Eva looked toward Evelyn.
“I believed the embryo inside you was mine.”
Evelyn held her daughter closer.
“You believed that made my body available.”
Eva lowered her eyes.
“Yes.”
The laboratories had identified the two babies.
They had not yet solved the older question.
Who had given birth to Evelyn and Eva?
The mitochondrial profiles confirmed both adult women came from Bianca’s maternal line.
Their birth dates matched.
Their father profiles differed.
Vittorio was Evelyn’s biological father.
Matthew was Eva’s biological father.
Evelyn and Eva were twins conceived during the same cycle from different fathers.
Bianca had carried and delivered them both.
Isabella had raised Evelyn.
The woman Evelyn called Mother had not given birth to her.

The woman who gave birth had spent decades teaching Eva that Evelyn stole her life.
👉 The infants’ true genetic origins were finally established, but the report also proved Bianca had given birth to both Evelyn and Eva—and deliberately allowed one twin to grow up believing the other had replaced her.
