“You could’ve led with that,” said St. George. He stopped on the landing and turned to her. “Why do you think so?”
Her cloak settled around her. “I cannot say,” she admitted. “I am positive something he has said is a lie, yet I cannot confirm why. The uncertainty is frustrating.”
“What did he say?”
Stealth went up the next flight of stairs without a word.
“Well?”
“He knows Billie Carter has a dolphin tattoo.”
“Is that …” He looked up at her and cleared his throat. “Is that wrong? I mean, besides the obvious way it’s wrong he knows that?”
Stealth’s head shifted inside her hood. “No. I performed her screening when we first took survivors into the Mount. The tattoo is on her left pelvic where it would be hidden by most items of clothing or underwear. From the color bleed, I would estimate she received it close to her seventeenth birthday.”
St. George followed her up the stairs. “So what’s the problem?”
“As I said, I am unsure. Yet I am convinced Maxwell has lied to us and it ties back to that statement.”
He pulled open the fourth-floor door and held it for her. The guard in the hallway directed them a few doors down to the pathology lab. Connolly was sitting in front of a microscope attached to a battered laptop computer. She glanced up as they entered, then back at the screen, as if she was worried what she’d been looking at would vanish. Her face was a mix of emotions.
“This had best be important, doctor,” Stealth said. “We do not have much time.”
“It’s important,” said Connolly. She waved them over to the counter and tapped a few keys on the laptop. She turned it so St. George and Stealth could see better.
On the screen St. George saw a trio of delicate shapes. They looked like silver spiderwebs, or maybe simple snowflakes, set against a white background. Each arm or branch looked like it was made of short segments. They drifted in the image, like underwater plants. One of the shapes shifted and St. George realized the arms extended out in several directions, like a Christmas tree ornament.
“Are they some kind of bacteria or something?” asked St. George. “Is it the ex-virus?”
Connolly shook her head. “They’re macromolecular complexes. Those arms are nanotubes, like flagella, but they’re all composed of different chemical compounds. The center mass is a mix of proteins and DNA, like you’d find in a virus. This whole structure’s approximately forty microns across.”
St. George blinked a few times and his mouth twisted up. “None of that means anything to me.”
“They’re nanites,” she said.
“A what?”
“A piece of nanotechnology,” Stealth said. “Machinery built or grown on a cellular level. Where did you find them?”
“They came from Madelyn.”
St. George looked up from the screen. “What?”
“Yesterday morning I decided to do a straight visual inspection of her blood at a higher magnification. Since the ex-virus mimics white blood cells, I thought it might be a way to spot a possible variation. I know it’s not supposed to mutate, but it was the only thing I could think of. That’s when I realized none of her blood cells were actually blood cells.”
She tapped her keyboard and a new image came up. The nanite webs had rolled their arms into coils and wrapped themselves into double-layered discs that were thicker at the edges. “These are from another one of her blood samples.”
Stealth’s head tilted inside her hood. “Their form now resembles erythrocytes. You are certain they are the same structures?”
Connolly nodded. “That’s why I didn’t notice them before. They were shaped like red blood cells and acting like them.” She hit a key and called up another picture. In this one dozens of webs were stretched out long and thin. The arms were gathered in parallel bundles. “These are from a tissue sample we took. Hundreds of them linked together to form bone muscle fibers.”
The doctor cycled the pictures back to the extended spiderweb and took in a controlled breath. “These things reshape themselves to mimic different cells, depending on where in the body they are. Blood cells, muscle cells, skin cells. They can even work together to imitate nerve cells.” She paused for a moment. “Do you have any idea what that means? An artificial neuron? That’s past Nobel Prize, that’s just … It’s impossible.”
“Clearly it is not,” said Stealth.
St. George tipped his head at the microscope image. “So these are in Maddy? They have something to do with her … condition?”
“They’re not in her, George,” Connolly said. “It’s all she is.”
He blinked. “What do you mean?”
“I mean …” The doctor took a breath. “Okay, I’m just guessing here because this is all way, way out of my league, and at this point I haven’t slept in two days.” She looked at Stealth. “You super-genius types can do what you want with this. Maybe you’ll come up with another way to interpret all the data.”
She took another slow breath and collected her thoughts.
“I think Emil Sorensen invented something amazing,” Connolly said. “He figured out how to biochemically engineer the dream nanite sci-fi writers have been talking about since the seventies. Almost a self-guided, synthetic stem cell, if you will. And, for some reason, he used them on his daughter. Maybe she had some injury or a disease or something. I don’t know her history well enough to guess what happened. But they ended up in her body, and they started multiplying and fixing things. Maddy got older, became athletic, and they supported and enhanced her whole system. If anything went wrong—muscle tears, injuries, whatever—the nanites would zoom in, multiply, and replace it until her own systems could catch up.”
“And then she died,” said St. George.
The doctor nodded. “And then she died. And they tried to fix it.”
They looked at the spiderweb on the screen.
“From what you and the captain have told me,” continued Connolly, “she was probably mangled, missing a lot of tissue mass. So the nanites did what they’re supposed to do. They replaced the damaged and missing sections. And they
