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.

My heart began pounding.

"Whose DNA test?"

A long silence followed.

Then Teresa whispered something that made my entire world turn cold.

"Ryan and Lucy."

I stopped breathing.

"Why would Ryan need a DNA test with his own daughter?"

Teresa began crying.

"Claire, I think that's the reason he started planning all this."

My hands shook.

"What does it say?"

She hesitated.

Then whispered:

"The report says Ryan isn't Lucy's biological father."

For several seconds, I couldn't move.

I had been faithful to Ryan throughout our marriage.

There had never been another man.

Lucy had been born after a difficult pregnancy.

Ryan was the only man I'd been with.

The result made no sense.

"That's impossible," I whispered.

Teresa's voice broke.

"I know."

Then she continued.

"But there's another name on the report."

My heart thundered.

"Whose?"

She hesitated.

Then said the name that made my knees give out.

"Dawson Mercer."
