Chapter 4 - The Ghost in the Machine

Arthur Vance did not waste a second. Within an hour, he had posted my bail—using his own funds to bypass the standard delay. By midnight, I was standing in his high-tech office on the top floor of the Vance Tower, overlooking the glittering skyline of the city.
“We cannot beat them by playing defense,” Arthur said, pacing in front of a massive digital whiteboard. “If we go to court tomorrow and try to prove you didn’t put those drugs in your closet, we lose. The burden of proof will be twisted against us. We must launch an overwhelming offensive. We need to prove Lauren did put them there, and we need to prove she poisoned Noah.”
“How?” I asked, holding a mug of black coffee with both hands to keep them from shaking. “She cleaned up the crime scene at the pool. She probably threw away the rest of the poisoned gummies.”
“She did,” Arthur said. “But Lauren has a weakness. She is arrogant, and she is incredibly vain. She documents her entire life on social media, and she uses a smart-home integration system that records every movement in her house.”
He tapped his tablet, and a map of Lauren’s sprawling mansion appeared on the screen.
“I have a digital forensics expert, Leo, who has been working since we left the precinct,” Arthur continued. “Leo, show her what you found.”
A young man with messy hair and thick glasses spun around in his ergonomic chair, his fingers flying across his keyboard.
“Hey, Rachel,” Leo said, offering a sympathetic smile. “So, here’s the thing. Your sister-in-law uses a highly encrypted home security system. But she also bought a cheap, smart-enabled pet camera to watch her designer French bulldog in the kitchen. That cheap camera? It has a security vulnerability the size of Texas. I bypassed it in ten minutes.”
The screen shifted to show a grainy, night-vision video feed of Lauren’s kitchen from three days ago.
On the screen, Lauren was standing by the kitchen island. She was holding a prescription bottle—the exact liquid diazepam bottle the police had found in my closet. She was carefully transferring the liquid into a batch of homemade, organic elderberry gummies. She was wearing silk pajamas, a smirk on her face, talking on speakerphone.
The audio was muffled, but Leo cleaned it up with a few keystrokes. Lauren’s voice echoed through the office, clear and chilling:
“...I’m telling you, Julian, it’s foolproof. He’s a hyperactive kid. I’ll give him one of these 'special' treats at the pool. He’ll look like he’s having a medical crisis, we’ll call the state, and with Evelyn’s help, the kid will be in our house by the weekend. Once we have guardianship, we access the trust, pay off your gambling debts to the cartel, and Rachel will be sitting in a prison cell wondering where she went wrong.”
My breath caught in my throat. I felt physically sick. My husband’s brother had gambling debts to a cartel. They were going to use my son’s life as a bank account to save themselves.
“This is it,” I whispered, tears of anger stinging my eyes. “This is the evidence. We can take this to the police right now!”
“Not yet,” Arthur said, his voice grave. “This is digital evidence obtained without a warrant. In a criminal court, Lauren’s high-priced lawyers would get this suppressed in an instant. They would claim we hacked her illegally—which we did—and it would be inadmissible. We need to use this to force her hand, to make her confess in a way that is admissible. And we need to secure the safety of the witness.”
“Sophie,” I realized. “They are keeping Sophie isolated.”
“Exactly,” Arthur said. “Tomorrow morning is the custody hearing. Lauren thinks she’s going to walk in, present her sob story, and walk out with Noah. We are going to let her think she’s winning until the very last second. But first, we need to get to Sophie.”

“How?” I asked. “Lauren has guards at her house, and she’s probably keeping Sophie locked in her room.”
Arthur smiled, a dangerous, sharp expression. “We don’t go to the house. We use the one thing Lauren values more than her family: her social standing.”
