My daughter’s ashes were still warm against my chest when my husband finally answered the phone.

Henri did not wait for the press photographers to clear out. He leaned close to my ear, his breath ragged.

"Madame Bennett," he whispered urgently. "We have a critical situation at the Zurich repository. The private security detail monitoring Beatrice’s legacy vaults has just flagged an unauthorized breach."

My smile vanished. Julian instantly stepped between Henri and the lingering journalists, shielding our conversation.

"What do you mean, a breach?" Julian demanded in a low, sharp voice. "All of Vance's co-conspirators are in federal custody or facing trial in Geneva. Who could possibly have the biological authorization codes to access Beatrice’s vault?"

"That is the problem, Mr. Vance," Henri answered, pulling a folded, encrypted biometric printout from his coat. "The vault was not breached using brute force or hacking. It was opened forty minutes ago using a direct retinal scan and a secondary tier-one genetic match."

Helena had overheard. She gripped the arms of her wheelchair, her breath hitching in her throat. "That is impossible. Only two living people possess the genetic sequence to open Beatrice's private research archives. Clara... and myself."

"There is a third, Madame," Henri said, his hands visibly shaking as he handed the document to me. "The system registered a ninety-nine percent maternal match to Beatrice Castellane. The user did not trigger the alarm. They entered the master pass-phrase left by your mother thirty years ago, accessed the cryogenic research wing, and withdrew one single specimen."

My heart pounded violently against my ribs. "What specimen?"

"Specimen 04-B," Henri whispered. "The embryonic tissue sample Beatrice preserved before her assassination. Clara... Vance didn't just conduct tests on you and Chloe. Before Beatrice was murdered, she was pregnant with twins."

The world seemed to tilt on its axis. The cheers of the crowd below on Michigan Avenue became a distant, muffled roar.

"Twins?" Helena gasped, pressing a trembling hand to her lips, tears springing to her eyes. "Beatrice was pregnant with twins? Vance told me... the coroner reported that the pregnancy was terminated during the initial attack in Zurich!"

"The coroner was on Vance's payroll," Henri said grimly. "And someone has just used that second child's genetic identity to access the deepest underground facility we own."

I stared down at the printout. Under the log-in verification timestamp was a short digital text note left directly in the terminal log, addressed specifically to me:

*Hello, sister. You took down the king on the board, but you forgot that a king always answers to the emperor. Come to the island of Saint Martin if you want to know who really killed our mother. And bring the locket.*

Julian grabbed my arm, his face pale with concern. "Clara, this is a trap. It has to be. Vance's syndicate is sprawling—there are dozens of rogue factions that could have cloned Beatrice's tissue or fabricated this data to draw you out of public protection!"

"A clone cannot know the pass-phrase Beatrice whispered to me on her deathbed," Helena said, her voice shaking with an unearthly terror. "There was a phrase Beatrice made me swear never to write down. Only three words. And according to this security log... that phrase was entered manually at the keyboard."

I looked back at the grand portrait of Chloe inside the glass institute.

I thought the war was over. I thought that by destroying Thomas, Victoria, and Adrian Vance, I had severed every thread of the nightmare that had stolen my daughter’s life.

But the darkness ran deeper than Chicago. It ran deeper than Geneva.
