Part 2: I discovered my husband was having an affair with my best friend while we were all on the same airplane—and neither of them knew I was there. Instead of confronting them, I sent a small, beautifully wrapped gift to their seats.

I couldn't breathe.

I looked toward my mother.

Then toward the photograph of the three children beside the airplane.

Suddenly, I understood why Ryan might have been so desperate to keep Dawson away from our family.

He hadn't merely hidden a child from Dawson.

He might also have been hiding a secret about Lucy.

But before I could ask another question, Teresa gasped.

A man's voice sounded in the background.

"Give me the phone."

Ryan.

I froze.

Teresa whispered, "Claire, I'm sorry."

Then I heard a struggle.

The call disconnected.

A moment later, my phone vibrated.

A new message appeared.

It contained a photograph of Lucy.

She was sitting beside an airplane window.

Tears streamed down her face.

In her hands was a piece of paper.

She'd written four words in thick black marker.

MOM, PLEASE FIND US.

I stared at her frightened face.

Then another message arrived.

From Ryan.
