The DNA Test

The lab was a 24-hour facility in Queens, the kind that catered to paternity disputes and immigration cases, places where desperation was the only currency accepted after midnight.

Claire sat in the waiting room, the fluorescent lights buzzing overhead like a trapped insect. David sat beside her, his head in his hands. He was still wearing the clothes from the gala, though the tie was gone and the shirt was stained with soot and blood.

He looked like a man who had survived a crash only to realize he was still falling.

"It takes 48 hours for a full profile," the technician had said, taking the swabs. "But we can do a preliminary screen for compatibility in two."

Two hours.

Two hours to undo thirty-four years of lies.

Claire watched the clock on the wall. The second hand ticked forward with agonizing slowness.

"He loved me," David whispered, his voice cracking. "In his own way, he loved me."

"He owned you, David," Claire said gently. "There's a difference."

"But he saved me. If he hadn't taken me... where would I be? With a single mother in Ohio? Poor? Forgotten?"

"Loved," Claire said. "You would have been loved by the woman who gave birth to you. Not used as a pawn to unlock a trust fund."

David looked up. His eyes were red-rimmed, exhausted.

"What if I am his son?" he asked. "What if Mary is wrong? What if the ledger is wrong?"

"Then we deal with it," Claire said. "But look at the facts, David. Look at the timing. Michael Kovac disappears in 1990. David Vance appears in 1992, but with a birth certificate that says he's two years younger than he looks. Arthur needed a grandson to get the money. He needed you."

"But biologically..."

"Biologically, Arthur is AB positive," Claire said. "I saw his medical file when I was doing the insurance audit last year. And you... you're O negative. The universal donor."

She reached into her bag and pulled out a small, folded piece of paper. It was a printout from a medical website.

"A parent with AB blood can pass on an A or a B," Claire said, pointing to the diagram. "They cannot pass on an O. It's genetically impossible for an AB parent to have an O child."

David stared at the grid. The logic was cold, mathematical, irrefutable.

"So he's not my father," David said. The words were heavy, final.

"No," Claire said. "He's not."

"Then who is?"

"We don't know yet," Claire said. "Mary said Sarah had an affair with Arthur. But if Arthur isn't the father... then Sarah must have been with someone else."

"Who?"

"Someone Arthur hated enough to steal his child," Claire said. "Someone he wanted to erase."

The door to the lab opened. The technician walked out, holding a clipboard.

"Mr. Vance?"

David stood up. "Yes."

"We ran the preliminary screen against the sample you provided from the... subject."

The subject. Arthur. Claire had swiped a hairbrush from his travel kit in the SUV before they fled the airfield.

"And?" David asked.

"There is zero probability of paternity," the technician said. "The alleles don't match at any locus. He's not your father."

David let out a breath he seemed to have been holding for a lifetime. He slumped back into the chair.

"Okay," he said. "Okay."

"But," the technician continued, flipping a page. "We did find something interesting when we ran your profile against the regional database. We have a partial familial match."

"A match?" Claire asked. "With who?"

"It's a second cousin match," the technician said. "Or maybe a great-uncle. Someone in the extended family tree."

"Who is it?" David demanded.

The technician looked at the name on the screen.

"The match is linked to a man named Silas Thorne."

Claire froze.

Silas. The private investigator. The man who had found Michael Kovac. The man who had shot Arthur.

"Silas isn't a Thorne," Claire said. "Marcus is a Thorne. Aris is a Thorne. Silas is just... Silas."

"According to the database," the technician said, "Silas is the estranged brother of Marcus Thorne's father. He changed his name in the 80s."

Claire looked at David.

The pieces slammed together with the force of a physical blow.

Arthur hadn't just hired a PI to find a child. He had hired a relative of his lawyer. A man who knew the family secrets.

But why would Silas be a match for David?

Unless...

"Sarah didn't have an affair with Arthur," Claire whispered.

She looked at the technician.

"Run the sample against Marcus Thorne," she said. "We have his DNA on the gun he dropped."

"I can do that," the technician said. "Give me twenty minutes."

He went back into the lab.

Claire turned to David.

"Mary said Arthur was obsessed with Sarah," she said. "She said he wanted her to be Evelyn. But maybe Sarah didn't want Arthur. Maybe she wanted someone else."

"Marcus?" David asked, repulsed.

"No," Claire said. "Not Marcus. The other brother."

She thought of Simon Vance, the black sheep in the mountains. And she thought of Silas, the PI who had saved them.

"Silas found you," she said. "He kept the file. He kept the secret. He shot Arthur to save you."

"Because Arthur paid him," David said.

"No," Claire said. "Arthur paid him to find a child. But Silas found *you*. And he kept watching you. For thirty years."

The door opened again. The technician looked pale.

"Mrs. Vance," he said. "You were right to ask for the comparison."

"Is Marcus the father?"

"No," the technician said. "But the markers indicate a sibling relationship between the father and Marcus Thorne."

He looked at David.

"Your father isn't Arthur Vance. And he isn't Marcus Thorne."

"It's Silas," David whispered.

The technician nodded.

"Silas Thorne is your biological father."
