Chapter 6 - The Shadow MechanicThree weeks passed.

I was finally discharged from the hospital, though my recovery was far from over. I moved into a secure luxury apartment complex downtown, protected by twenty-four-hour private security funded by my father’s trust. Emma was back in school, thriving under the care of a child psychologist and loving every second of our peaceful, quiet evenings together.
My casts were replaced with lighter fiberglass boots, allowing me to move around in a wheelchair. The physical wounds were healing, but the mystery of my accident remained an open, agonizing void.
The police investigation into the car crash had hit a dead end. While the brake lines were confirmed to have been severed with a mechanical shear, Caleb had a ironclad alibi for the exact hours the car was tampered with: he had been on a live, televised panel at a business conference in front of three hundred people.
He was guilty of assault, abuse, and embezzlement, but the police couldn't prove he personally touched my car.
"He hired someone," I told Arthur Vance as we sat in my living room, files spread across the glass coffee table. "Caleb is a coward. He never does his own dirty work."
"We checked his phone records, his bank statements, and his private messaging apps," Vance said, rubbing his temples. "There is no record of him communicating with any mechanics or local criminals prior to the crash."
I leaned back in my wheelchair, staring at the photos of my wrecked car taken by the insurance adjuster. The slice through the hydraulic line was clean, precise—done by someone who knew exactly where to cut without causing an immediate leak, ensuring the brakes would fail only after the car reached high speeds on the mountain descent.
"Wait," I said, zooming in on one of the engine bay photos. "Look at the master cylinder."
Vance leaned in closer. "What about it?"
"That’s a custom aftermarket brass fitting," I pointed out, my auditor's eye catching the tiny anomaly. "My car was a standard factory model. Caleb always took the cars to the official dealership for servicing. The dealership would never use non-OEM aftermarket parts."
I grabbed my phone and called the dealership’s service department manager, a man named Marcus whom I had spoken with dozens of times over the years.
"Mrs. Walker!" Marcus said, his voice brimming with sympathy. "We were so sorry to hear about your accident. How are you feeling?"
"Marcus, I need to ask you something about my vehicle service records," I said directly. "Did your shop install an aftermarket brass fitting on my brake master cylinder during its last routine service?"
"Absolutely not," Marcus replied immediately. "We only use certified factory parts. Besides, Mr. Walker picked up your car from our shop two days before the accident. He said he was taking it to a specialized private garage for a 'performance tune-up'."
My pulse quickened. "Which garage, Marcus?"
"He didn't say, but I remember seeing the tow truck driver who picked it up. It wasn't a standard roadside service. It was a flatbed from a local place called Miller’s Performance Auto out in the industrial district."
I looked at Vance, whose eyes broadened with sudden realization.
"Miller’s Performance," Vance repeated softly. "The owner is Greg Miller. He’s Victor Walker’s former brother-in-law."
The missing link. Caleb hadn't contacted the mechanic directly—his brother Victor had arranged it through his own family network, keeping Caleb’s hands completely clean.
"Get the district attorney on the phone," I said, my blood running hot. "We’re going to pay Mr. Miller a visit."
An hour later, two unmarked police cruisers accompanied Vance and me to the grimy, oil-stained garage on the outskirts of the city.
Greg Miller—a burly man in grease-stained overalls—was underneath a hoisted pickup truck when we walked in. When he saw the police officers and me rolling in my wheelchair, he dropped his wrench. It clattered against the concrete floor with a deafening bang.
"Greg Miller?" the lead detective asked, stepping forward with a search warrant.
Miller wiped his hands on a dirty rag, his eyes darting frantically toward the back exit. "What is this about? I haven't done anything wrong."
I rolled my wheelchair closer, looking him dead in the eye. "You cut my brake lines, Greg. You used a brass bypass fitting to delay the fluid pressure loss until I hit fifty miles per hour on the interstate hill."
Miller turned pale. "You... you don't know what you're talking about."
"We have the flatbed transport logs, Greg," Vance interjected smoothly, holding up a stack of subpoenaed records. "We have the security footage from the dealership showing your truck towing her car. And more importantly, we just pulled Victor Walker’s offshore transaction logs. He wired fifty thousand dollars to your wife’s account the morning after the crash."
Miller dropped his rag. His knees shook as he looked at the police officers reaching for their handcuffs.
"It wasn't my idea!" Miller suddenly burst out, terror cracking his voice. "Victor told me it was just an insurance scam! He said the car was empty! He swore nobody was going to be driving it!"
"He lied to you, Greg," I said coldly. "I was inside that car. My nine-year-old daughter was supposed to be in the passenger seat next to me."

Miller fell back against a workbench, tears carving clean streaks through the grease on his cheeks. "Oh God... Oh God, I didn't know... Victor told me Caleb wanted to write off the vehicle for the payout!"
"If you want to avoid spending twenty years in prison as a co-conspirator to attempted murder," the detective said, snapping the handcuffs around Miller's wrists, "you better start talking into a tape recorder. Right now."
