MY BILLIONAIRE HUSBAND GAVE ME HIS UNLIMITED BLACK CARD—THEN BEGGED ME TO STOP SPENDING

The thirty-seventh notification arrived on Alexander's phone while Sophia was explaining why Paris had become unbearable.

He wasn't listening anymore.

He was staring at the screen.

HARBORLIGHT HERITAGE AUCTION — PAYMENT APPROVED.

Below it appeared an amount large enough to purchase a Manhattan penthouse.

Then another detail caught his attention.

LOT 37: ORIGINAL MERCER HOUSE ARCHIVE — ACQUISITION COMPLETED.

Alexander gripped his phone.

Sophia stopped speaking.

"Alex?"

He scrolled backward through the notifications.

Thirty-seven charges.

Thirty-seven purchases.

All from the same private auction.

None of them jewelry.

None designer handbags.

Every transaction involved an original architectural object, painting, historical manuscript, or documentary collection from Mercer House, a nineteenth-century waterfront estate scheduled for demolition under a redevelopment plan controlled by Grant Global Properties.

Alexander knew the name.

He knew it very well.

"What is it?" Sophia asked.

He stood so abruptly that his chair struck the table behind him.

"Erin."

Sophia frowned.

"Your wife?"

Alexander was already calling me.

Back at the Hudson estate, I watched his name illuminate my screen.

I didn't answer.

Not because I wanted revenge.

Because I wanted to finish reading the letter in front of me before anyone explained what I was supposed to think.

It had arrived electronically with the final auction lot.

Thirty-seven lots had been sold separately by an independent historical auction house under instructions from the previous custodians of Mercer House.

I purchased all thirty-seven.

The auction required immediate payment for each lot. The transactions had been approved using the card Alexander had explicitly given me, although whether the purchases would ultimately remain valid was a separate legal question.

I understood that he could dispute the charges.

I understood that spending permission during a domestic argument was not the same thing as unlimited legal authority.

But I had obtained copies of the purchase confirmations, auction descriptions, and provenance records.

And what I found in Lot 37 mattered more than the money.

The final lot contained an original collection of letters written by a woman named Eleanor Mercer.

My grandmother.

The grandmother I had been told died with nothing but debts.

I unfolded the first letter.

My darling Margaret,

If the trustees ever tell you that Mercer House belongs to the Grant family, ask them to produce the transfer deed. They will have every document except the one that matters.

I stopped breathing.

Margaret was my mother.

She died when I was nineteen.

For most of my adult life, I believed Mercer House had been a property she once visited during childhood.

She never told me it had belonged to her family.

And she certainly never told me the Grant family had any connection to it.

A second document lay beneath the letter.

An old ownership agreement.

The original ink was faded, but one paragraph was clear.

The estate had been placed under a charitable preservation trust intended to support a public arts school and community housing.

The Grant family held administrative responsibilities.

Not unrestricted personal ownership.

I read the paragraph again.

Then I understood why Alexander's grandfather had been obsessed with acquiring the property.

And why Alexander's company wanted to demolish it.

At 12:14 a.m., headlights flooded the dining-room windows.

Alexander was home.

I heard his car door slam.

Then the front entrance opened.

"ERIN!"

His voice echoed through the house.

I remained seated.

He appeared in the dining room, still wearing his charcoal coat.

His face was pale.

"Tell me you didn't do what the auction confirmations say."

I looked up.

"Good evening, Alexander. How was dinner?"

He ignored the question.

"Do you have any idea how much money you've spent?"

"Yes."

"Those weren't personal purchases!"

"They were offered at a publicized, legally conducted private auction."

"That's not what I mean."

I folded my hands.

"Then explain what you mean."

He leaned across the table.

"Those items are connected to an acquisition my company has been negotiating for eighteen months."

"Then your company should have bid on them."

His jaw tightened.

"Erin, don't play games."

I held out one of the purchase documents.

"Why does your redevelopment subsidiary describe Mercer House as an unencumbered corporate asset when my grandmother's archive says it was entrusted to a charity?"

For the first time, Alexander lost his expression of anger.

He stared at the paper.

Then looked at me.

"Where did you get that?"

I placed Lot 37's inventory beside his untouched anniversary dinner.

"Your card helped me find it."

His eyes narrowed.

"Those documents are old."

"Then they should be easy to explain."

He said nothing.

I studied his face.

"Did you know my grandmother was Eleanor Mercer?"
