The Lab Wait

Sarah sat in the lobby of the precinct, the plastic chair digging into her back, but she barely felt it. The cameras were flashing outside, a strobe-lit storm against the glass doors, but the real chaos was unfolding in her inbox.

The results from the independent DNA lab were pending.

"They're taking too long," Maya whispered, her leg bouncing nervously. She was scrolling through Twitter on a new burner phone Helen, the lawyer, had procured. "People are saying the documents are fake. That Robert was a disgruntled employee. That the bomb was yours."

"Let them talk," Sarah said, though her own hands were trembling. "The DNA is the hard stop. It doesn't care about narratives."

She looked at Marcus. He was slumped in the chair next to her, still clutching the evidence bag with the coffee cup. He looked exhausted, his face grey with fatigue.

"Are you sure about the sample?" Sarah asked.

"I took it straight from the cup to the courier," Marcus said. "Chain of custody is solid. The lab is independent. It's in Switzerland. Caldwell can't touch it."

"He can touch anything," Sarah murmured.

Her phone buzzed. An email.

*Subject: Settlement Offer.*

It wasn't from a lawyer. It was from *E*.

Sarah opened it. No text. Just an attachment.

A photo of the DNA lab in Zurich. The building was on fire.

"Mom?" Maya asked, seeing her face.

"He burned it," Sarah whispered. "He burned the lab."

Marcus grabbed the phone. He swore, a harsh, guttural sound. "The digital records are backed up. They have to be."

"Not if he got to the servers first," Sarah said. She looked at the timestamp on the photo. *Ten minutes ago.*

Caldwell wasn't just covering his tracks. He was scorching the earth.

"We still have the cup," Marcus said, holding up the bag. "We can send it somewhere else."

"Where?" Sarah asked. "Every lab in the country is either owned by a conglomerate or susceptible to a federal warrant. If we send it, we lose it."

"We don't need a lab," a voice said from the doorway.

Sarah looked up.

It was Dr. Thorne.

He was wearing handcuffs, flanked by two federal agents. But he wasn't looking at them. He was looking at Sarah.

"I can run the test," he said.

"You're a monster," Sarah said, standing up. "You helped her. You helped them harvest those children."

"I helped them survive," Thorne said, his voice quiet. "Do you think Elena would have stopped at three? Or six? I kept them alive. I kept the doses low. I forged the records to say they were thriving when they were dying."

"Why should I believe you?"

"Because I have the control sample," Thorne said.

Sarah froze. "What control sample?"

"The one from 1988," Thorne said. "From the amniocentesis. Before the treatments started. Before the damage."

"Where is it?"

"It's in the only place Elena never looked," Thorne said. "Because she thought it was trash."

He looked at the evidence bag in Marcus's hand.

"You have the cup," Thorne said. "I have the baseline. If you can get me to a microscope and a sequencer, I can prove Caleb is Thomas's son. And I can prove he's a chimera."

"A what?" Maya asked.

"A chimera," Sarah realized. "Two sets of DNA. One from the donor... and one from the host."

"The treatments altered them," Thorne said. "But the original code is still there. Buried deep. I can find it."

Sarah looked at the agents. They were watching her, impassive.

"He's in custody," Sarah said. "We can't just borrow him."

"You don't have to," Helen said, striding into the lobby, her heels clicking on the tile. She was flanked by two men in dark suits who didn't look like lawyers. They looked like private security. Very expensive private security.

"I just filed a motion for independent verification of evidence," Helen said, handing a paper to the agents. "Dr. Thorne is now a material witness for the defense. And under the Patriot Act, section 412, we have the right to secure his testimony immediately if there is a credible threat to his life."

She pointed to the photo of the burning lab on Sarah's phone.

"I'd say firebombing a Swiss facility constitutes a credible threat," Helen said.

The agents looked at the paper. They looked at Helen. Then they looked at each other.

One of them nodded. He uncuffed Thorne's hands.

"You have two hours," the agent said. "Then he goes to federal lockup."

"Where can we go?" Marcus asked. "We need a lab."

"The university," Sarah said. "My old law professor's husband runs the biology department. He owes me a favor."

They moved fast. Helen’s security team hustled them into a waiting van—armored, bulletproof. As they pulled away from the precinct, Sarah looked back.

A black sedan was idling across the street. Argus.

"They're following us," Maya said.

"Let them," Sarah said. "We're done running."

They reached the university lab in twenty minutes. It was quiet, the students gone for the break. Dr. Thorne went to work immediately, his hands moving with a precision that belied his age and his crimes.

Marcus set up the sequencer. Sarah stood guard by the door, the tire iron heavy in her hand.

"It's going to take time," Thorne said, peering into the microscope. "The markers are faint."

"We don't have time," Sarah said.

Her phone buzzed. A text.

*Check the attic vents.*

It was the same message she had received weeks ago. The one that had started everything.

But the number wasn't unknown this time.

It was from *Caleb*.

Sarah stared at the screen. Caleb was dead. He had died in the explosion.

Unless...

*I'm not dead,* the next message read. *But I'm close.*

Sarah typed back, her fingers trembling. *Where are you?*

*The bridge,* he replied. *Where it started.*

Sarah looked at the map. The bridge where Elena had tried to kill him. Where Robert had created the diversion.

*Why are you there?*

*Because that's where she put the bomb,* Caleb wrote. *The real one.*

Sarah frowned. "What bomb?"

*The one she didn't use on the house,* Caleb typed. *The one she's saving for the courthouse.*

Sarah felt the blood drain from her face.

"Helen," she said. "Call the judge. Clear the building."

"What?" Helen asked, looking up from her legal pad.

"Elena isn't done," Sarah said. "She's not trying to win the case. She's trying to eliminate the court."

"How do you know?"

"Because my dead brother just told me," Sarah said.

And then the lights in the lab went out.
