Chapter 3 - The ER Revelation

Sirens cut through the icy night as three ambulances and two fire trucks roared down the winding driveway of the estate. Paramedics spilled out, rushing oxygen masks to the coughing guests scattered across the lawn.
When the lead EMT saw Piper's condition, his face hardened instantly. "High-concentration carbon monoxide exposure! She needs oxygen immediately! Get her on the stretcher!"
I rode in the back of the ambulance, holding Piper's ice-cold hand as the oxygen mask hissed over her mouth and nose. The monitors beeped rhythmically, showing her dangerous carboxyhemoglobin levels.
"Mom..." Piper rasped under the mask, her eyes wet with tears. "She... she locked me in the basement with the old heater... whenever I tried to tell the guests... she called me crazy..."
"Hush, sweetie. Don't talk," I pleaded, kissing her forehead. "Save your strength."
When we arrived at the hospital emergency room, doctors swarmed her gurney. They rushed her into a high-flow oxygen treatment chamber while I was forced to wait behind the sliding glass doors, clutching her dirt-stained apron against my chest.
As I stood in the corridor, shivering in my damp clothes, two police officers walked down the hall toward me. Behind them walked Brooke, flanked by her husband, Julian—a high-powered defense attorney wearing a pristine cashmere coat.
Julian stepped forward, putting on his professional, persuasive voice. "Clare, thank God Piper is getting treatment. This entire situation is a tragic accident. The basement HVAC system malfunctioned—"
"An accident?" I cut him off, stepping toward him until our faces were inches apart. "Julian, the batteries were pulled out of the carbon monoxide detector. My daughter was wearing rags and covered in shoe polish! She was forced to sleep on the floor by the front door!"
Brooke hid behind Julian's shoulder, putting on a tearful performance for the police officers. "Officer, my sister has been under immense stress. Piper has been suffering from severe emotional disturbances since Clare went on her business trips. She... she dressed herself in those clothes! I was trying to protect her from embarrassing herself!"
I let out a harsh, disbelieving laugh. "Protect her? You stamped your muddy boot on her leg ten minutes ago!"
"That's enough," the lead detective said, stepping between us. "Mrs. Vance, we have fire inspectors currently sweeping your sister's home. If there is evidence of foul play or child endangerment, criminal charges will be filed."
"She's lying!" Brooke sobbed theatrically to the officer. "Check her bank accounts! She left Piper with us because she couldn't afford her private school tuition!"
I reached into my coat pocket, pulled out my phone, and opened a saved audio file.
Three days ago, right before I lost cell reception on my flight home, my security app had recorded a brief voicemail left accidentally by Brooke's home intercom system.
I pressed play.
Brooke's crisp, cruel voice blasted through the hospital hallway:

"Make sure you scrub every pair of shoes before the guests arrive, you little parasite. And if you dare open your mouth to anyone about the heat, I'll tell your mother you ran away."
Julian's mouth snapped shut. The police officers' expressions transformed instantly into stone.
