I walked into my bedroom and found my husband’s mistress at my vanity,

The Metropolitan Detention Center in Brooklyn smelled of industrial bleach, floor wax, and misery.

It was 4:00 PM when Naomi and I were escorted into the high-security attorney-client conference room. The room was small, lit by buzzing fluorescent tubes, with a scratched laminate table bolted to the linoleum floor.

The door on the opposite side clicked open, and Sloane Mercer was led in by a female corrections officer.

She had spent eighteen hours in custody. The designer gown had been replaced by a stiff, oversized two-piece uniform of coarse khaki cotton. Her golden hair was pulled back in a tangled, messy knot, and without her makeup, her face looked hollow, young, and utterly terrified.

When she saw me sitting across the table, she stopped. Her shoulders slumped, and for a moment, I thought she might collapse.

“Sit down, Ms. Mercer,” Naomi said, gesturing to the metal chair.

The guard pushed Sloane gently into the seat, clicked her handcuffs to the steel D-ring in the center of the table, and stepped outside, closing the heavy steel door behind her.

Sloane stared down at the scratched table. Her wrists were raw and red from the metal cuffs.

“Are you here to gloat?” Sloane whispered, her voice rough. “Did you come all the way to Brooklyn just to watch me cry?”

“I don't need to gloat, Sloane,” I said calmly, resting my hands on the table. “You put yourself in that chair. I merely stepped out of the way.”

Sloane swallowed hard, tears welling in her rimmed eyes. “Grant told me you were weak. He told me you were just some sheltered heiress who stayed in her library all day, that you didn't care about anything. He swore he had the divorce papers drawn up. He said we were going to announce our engagement in Paris next spring.”

“Grant tells everyone what they want to hear,” I replied. “He told his board he was a genius. He told his mother he was untouchable. And he told you that you could steal my grandmother’s pearls without consequences.”

Sloane flinched. “I didn't steal them! He unlocked the armoire! He handed me the box! He said... he said they were family heirlooms that belonged to whoever was the woman of the house.”

“They belonged to Eleanor Vance,” I said, my voice hardening. “A woman who drove an ambulance in London while bombs were falling, while your ancestors were probably swindling farmers. You put them on your neck like a cheap costume prize.”

Sloane buried her face in her cuffed hands, her shoulders shaking with silent, ragged sobs. “I’m looking at ten to fifteen years. That’s what the public defender told me this morning. Ten to fifteen years for grand larceny, conspiracy, and wire fraud. My life is over. I’m thirty-one years old.”

Naomi leaned forward, opening her briefcase. She laid a single typed document on the table.

“It doesn't have to be fifteen years, Ms. Mercer,” Naomi said.

Sloane lifted her head, sniffing, looking at the paper through swollen eyes. “What is that?”

“A proffer agreement from the United States Attorney’s Office,” Naomi said. “With an annex from the Vance Estate regarding civil restitution.”

Sloane looked at me, bewildered. “You’re offering me a deal? Why? You hate me.”

“Hate is an expensive emotion, Sloane, and I don't waste capital on bad investments,” I said. “I don't care about you. You are a symptom of Grant’s rot, not the cause. But Grant is currently attempting to place the entire blame for the offshore accounts on your shoulders. His legal defense team, headed by Arthur Sterling’s criminal partners, is preparing to claim that you were the mastermind. That you used your consulting firm to embezzle the money without Grant’s knowledge.”

Sloane’s jaw dropped. “That’s impossible! He signed every wire!”

“He used digital authorization keys registered to your IP address,” Naomi explained cold-bloodedly. “He used your laptop in the hotel rooms. He set you up as the fall guy from day one, Sloane. If this goes to trial without your cooperation, Grant will walk away with probation or a minimum-security camp, and you will serve a decade in a federal penitentiary.”

Sloane’s face went pasty white. She began to hyperventilate, clutching her chest. “The bastard... the sick, lying bastard!”

“You have something we want,” I said, cutting through her panic.

Sloane looked up, desperate. “What? What do I have? They seized my apartment, my car, my accounts—”

“Grant’s personal cold-storage hard drive,” Naomi said. “The black SanDisk drive he kept in your apartment safe. We know he transferred the Whitaker family’s shadow ledger onto it two weeks ago when the SEC began its preliminary inquiries.”

Sloane went completely still. Her eyes flickered.

“How do you know about that?” she whispered.

“Because Grant is predictable,” I said. “He never keeps his leverage where his mother can find it, and he never keeps it where I could find it. You were his safety deposit box. Do you have the drive, Sloane?”

Sloane sat in silence for ten long seconds. The hum of the fluorescent lights seemed to grow louder.

Finally, she leaned forward, her voice dropping to a trembling murmur. “It’s not in the safe. The FBI searched the apartment; they didn't find it. I hid it.”

“Where?” Naomi asked.

“If I give it to you,” Sloane whispered, looking directly into my eyes, pleading for her life, “what happens to me?”

“The grand larceny charges regarding the pearls will be reduced to misdemeanor trespass,” Naomi said. “The federal prosecutors will accept your plea as a cooperating witness. You will serve two years at a low-security camp in Danbury, and the Vance Estate will not pursue a civil judgment against whatever personal assets you have left. You will walk out at thirty-three with your life intact.”

Sloane closed her eyes. Two thick tears tracked through the grime on her cheeks.

“It’s inside an antique silver vanity mirror,” Sloane said softly. “The one Grant bought me at a flea market in Paris. You have to unscrew the handle with a jeweler's screwdriver. The flash drive is sealed in the hollow stem. The password is his mother’s maiden name and the date of his father’s death.”

Naomi made a quick note on her legal pad, then stood up, sliding the proffer agreement toward Sloane.

“Sign on the last page, Ms. Mercer,” Naomi said. “The detective is waiting outside.”

Sloane took the pen with trembling, clumsy fingers. She signed her name. When she pushed the paper back, she looked at me with an expression of complete, exhausted surrender.

“He told me you would break,” Sloane whispered. “He told me you didn't have the stomach for blood.”

I stood up, pulling my leather gloves on, smoothing the fingers one by one.

“My grandmother survived the Blitz, Sloane,” I said quietly. “My father broke corporate raiders before breakfast. Grant was just a boy playing with matches in a house he didn't build.”

I walked toward the door. As the guard unlocked it, I looked back one last time.
