Emelie was in the laundry room, the dryer tumbling rhythmically in the background. She held a burner phone to her ear.

"Ghost," a voice crackled. It was Dr. Vance. "Your protocol... it's genius. The board is stunned. They want to nominate you for the Lasker Award."

"No names," Emelie whispered.

"Dr. Dillon Hunt is demanding a meeting," Vance said. "He says he knows the syntax. He says only one person writes formulas like that. Garvin Glover."

"Garvin is dead," Emelie said.

"He thinks you're his ghost. Literally. Or a protégé. He's going to be at the Bio-Ethics Summit in Baden-Baden next week. He wants to meet the Ghost."

Baden-Baden.

That was where the Wilder family castle was. Where they were going.

"Tell him Ghost doesn't do meetings," Emelie said.

She hung up and broke the SIM card in half.

She walked past the study. Clifton was shouting.

"...I don't care! The match is perfect! We have to do the transplant now!"

Emelie froze.

Match. Transplant.

"Lily is the only viable donor," Clifton said.

Emelie's heart stopped.

He wasn't just using her mother's samples.

He was using Lily.

Her mother's marrow must have run out or failed. And Lily... Lily shared 25% of her grandmother's DNA.

But that didn't make sense. HLA matching required specific antigen compatibility, not just shared DNA percentages. For Lily to match Eleanora, Eleanora would have to be...

Related.

The realization hit Emelie like a freight train. Eleanora wasn't just a mistress. She was family. But how?

He was taking Lily to Germany to harvest her bone marrow for Eleanora.

The horror was so absolute it nearly knocked Emelie to the floor.

She ran upstairs.

She didn't scream. She didn't cry.

She pulled out a suitcase.

She packed Lily's clothes. She packed her own.

Then she went to the safe.

She took out the laptop. She took out a portable nanopore genetic sequencer-a device no larger than a smartphone but capable of full genome sequencing. She took out a voice recorder.

She packed them all.

She sat on the edge of the bed, shaking.

"You will not touch her," she whispered to the empty room. "Over my dead body."

She opened the secure satellite uplink on her laptop. She found an old encrypted contact ID. Dillon Hunt.

She typed a message.

I will be in Baden-Baden. If you want to meet Ghost, find a way to get into the Wilder Castle.

She hesitated. This was dangerous. Unmasking herself could lose her everything.

But she needed an ally. And Dillon was the only one who respected the science.

She hit Send.

A minute later, a reply came.

I'll be there.

The Teterboro tarmac was windy.

The Wilder corporate jet, a sleek Gulfstream G650, gleamed in the sun.

Emelie held Lily's hand tightly. Her grip was iron.

"Mommy, you're hurting me," Lily complained.

"Sorry, baby," Emelie loosened her grip, but didn't let go.

Eleanora was already at the stairs. She was wearing a white Chanel suit and oversized sunglasses. She looked like she was going on a honeymoon.

She saw Emelie and frowned.

"Oh," Eleanora said. "Clifton said you weren't coming."

"Clifton was wrong," Emelie said, brushing past her.

They boarded.

The cabin was luxurious, with cream leather seats.

Eleanora sat in the main facing seat. Clifton sat next to her.

Emelie took the seat across the aisle, pulling Lily into her lap.

"Can I sit with Daddy?" Lily asked.

"No," Emelie said firmly. "You stay with me."

The plane took off.

As they reached cruising altitude, the pressure changed.

Lily started to cry. "My ears! Mommy, my ears hurt!"

Clifton looked up from his iPad, annoyed. "Can you keep her quiet? Eleanora has a headache."

Eleanora rubbed her temples dramatically. "It's fine, Clifton. Poor thing."

She reached into her purse and pulled out a lollipop. "Here, sweetie. The sugar helps."

Emelie slapped the lollipop out of her hand. It landed on the carpet.

"She doesn't need sugar," Emelie snapped.

She turned Lily's head to the side. She remembered the integrative medicine techniques her father had researched for pediatric pain relief. She found the pressure point behind the earlobe-the Yifeng point. She pressed firmly and massaged in a circular motion. Then she massaged the Eustachian tube down the neck.

"Swallow, baby," Emelie whispered.

Lily swallowed. Her eyes widened. "It popped!"

"Better?"

"Yeah!" Lily smiled. She snuggled into Emelie's chest and closed her eyes.

Clifton watched the whole thing. He looked stunned.

"Where did you learn that?" he asked.

"I read my father's journals," Emelie said coldly. "He knew more than just immunology."

She put on her noise-canceling headphones.

She opened her Kindle. But she wasn't reading a book. She had hacked the Kindle to display PDFs.

She was reading the latest paper on Graft-versus-Host Disease in Pediatric Donors.

Clifton glanced over. He saw dense text, charts, graphs.

He squinted. "What are you reading?"

"A thriller," Emelie said, turning the page. "About a husband who tries to kill his wife."

Clifton looked away, uncomfortable.

Turbulence hit. The plane dropped ten feet.

Eleanora gasped and grabbed Clifton's hand. "Clifton!"

Clifton covered her hand with his, murmuring reassurances.

Emelie watched them.

She felt nothing. No jealousy. No pain.

Only target acquisition.

She looked at Lily, sleeping peacefully.

I will destroy you both, she thought. And I will use your own science to do it.

The pilot's voice came over the intercom. "Preparing for landing in Baden-Baden."
