Marcus reached for the door lock.

I grabbed his wrist.

“No.”

He looked at me.

I shook my head.

“I want to hear the truth from her.”

I unlocked the door.

Sarah stepped inside.

She looked nothing like the sister who had held me at Liam’s funeral.

Her hair was wet from the rain.

Her eyes were red.

And she was holding something tightly against her chest.

An envelope.

She looked at Marcus.

Then at me.

“Emily,” she whispered, “Liam didn’t die because he discovered the company’s secret.”

She walked toward me.

“He died because he discovered ours.”

I stared at her.

“What do you mean, ours?”

Sarah looked down at the envelope in her hands.

Then she slowly held it out to me.

“This was supposed to be destroyed.”

I took it.

There was only one thing written on the front.

FOR EMILY — OPEN ONLY IF SARAH LIES TO YOU.

PART 3

I stared at the envelope in my hands.

FOR EMILY — OPEN ONLY IF SARAH LIES TO YOU.

I couldn’t even bring myself to open it.

I looked at my sister.

“What is this?”

Sarah wiped the tears from her face.

“It belonged to Liam.”

Marcus stepped closer.

“Sarah, don’t do this.”
