Chapter 12: The Ink on the Foot

*Exchange.*

The word was scratched into the metal with jagged, angry force. It wasn't written. It was gouged.

I sat back on my heels, the dusty air of the back parlor swirling around me. Ben was silent, the beam of his flashlight fixed on the contents of the box spread out on the floor.

"What does it mean?" he asked finally.

"It means exactly what I was afraid of," I said.

I picked up the birth certificate for Leo Sterling again. *June 14, 1988.* Clara's son.

Then I picked up the intake form for Baby Girl Doe. *June 15, 1988.* The foundling. Me.

The dates aligned perfectly with the lie Edith had told me my entire life. She said she adopted me as a baby. She said my mother was a "troubled girl" who couldn't keep me.

She just left out the part where she traded one baby for another.

"She swapped us," I whispered. "She took Clara's son, Leo. And she replaced him with... with me."

"Why?" Ben asked. "If she wanted a baby, why not just keep Clara's?"

"Because Clara wouldn't give him up," I said, pointing to the letter. "She was running. She had a go-bag packed. She was going to disappear with him."

I looked at the intake form again. *Abandoned at Fire Station 4.*

A chill went through me. Fire Station 4 was in the city, miles away from the Sterling estate. But it was only a few blocks from where Edith had lived in her "bachelorette" apartment before she married into the family money.

"She needed a baby," I said, the pieces clicking into place like the tumblers of a lock. "She needed an heir to secure the grandfather's estate. The will said 'the first grandchild born of my body.' But Edith couldn't have children. Everyone knew that."

"So she stole Clara's," Ben said.

"She stole Clara's," I agreed. "But she couldn't just produce a baby out of thin air if Clara was still around screaming about a theft. She needed Clara gone. Institutionalized. And to do that, she needed to prove Clara was unstable."

I looked at the metal box. At the word *Exchange*.

"She swapped a live baby for a foundling," I said. "She probably told everyone Clara had lost the baby, or killed it, or... God knows what. And then she 'adopted' the poor, abandoned foundling out of the goodness of her heart."

"And Clara's son?" Ben asked. "What happened to Leo?"

I looked at the gold ring in the velvet pouch. *For my Leo. Always.*

"Edith raised him," I said. "She raised him as her own."

Ben looked confused. "But Edith only has one son. Mark."

I stared at him. The room seemed to tilt.

Mark.

Mark Sterling. The Golden Child. The one who looked nothing like Edith. The one who had always been treated like a prince while I was the scullery maid.

I scrambled for my phone. I pulled up a picture of Mark from his Facebook profile. He was grinning on a boat, wearing sunglasses.

I swiped to a picture of Clara I had taken yesterday at the facility. It was blurry, her face slack with age and medication.

But the eyes.

Mark had Clara's eyes. The same deep, startling blue.

And the chin. The slight cleft that Edith definitely didn't have.

"Oh my god," I whispered. "It's Mark. Mark is Leo."

Ben looked at the phone, then at me. "Edith raised her sister's son as her own? And she raised you... the random baby she picked up... as her niece?"

"It explains everything," I said. "Why she hates me. Why she treats me like an employee. I'm not blood. I'm just a prop she used to cover her tracks."

I looked down at my own hands. They were shaking.

I wasn't a Sterling. I wasn't even a poor relation. I was *Baby Girl Doe*. A throwaway child used as a placeholder in a dynasty.

And Clara? The woman I had just started to hope was my mother? She wasn't my mother either.

She was just another victim.

But there was one thing that didn't fit.

The footprint.

I grabbed the birth certificate I had found in the first lockbox—the one Edith had forged for me. The one with *my* name and *my* birth date.

It had footprints on it.

I grabbed the intake form for Baby Girl Doe. It had footprints too.

I held them side by side under the flashlight beam.

They didn't match.

The arch on the Baby Girl Doe print was high. The toes were long.

The arch on my birth certificate—the forgery—was flat. The toes were shorter.

"They're different," I said. "Ben, look. These aren't the same baby."

Ben squinted at the papers. "You're right. The heel shape is totally different."

My mind raced. If I wasn't Baby Girl Doe... and I wasn't Clara's son...

Then who was I?

I looked back at the metal box. I shook it. Something rattled inside, stuck under the lip of the bottom.

I dug my fingernail in and pried it out.

It was a hospital bracelet. Plastic, yellowed with age. The kind they put on newborns.

I held it up to the light.

The name on the bracelet wasn't Doe. And it wasn't Sterling.

It was typed in faded blue ink.

*Baby Girl Thorne.*

Thorne.

Dr. Thorne. The family doctor who had signed the fake death certificate. The man Edith had paid off.

I stared at the bracelet.

I wasn't a foundling.

I was the doctor's daughter.
