I was certain I had uncovered my neighbor’s wife’s secret. Then she told me the man was her husband’s supposedly lost twin. That’s when the real mystery began.

I frowned.

“You mean the man I saw was actually Michael?”

“No.”

She looked at me.

“That’s where things get strange.”

She pulled out her phone and showed me a photograph.

There were two identical men standing beside each other.

I couldn’t tell them apart.

“This is Mark,” she said, pointing left.

“And this is Michael.”

I stared at the picture.

“Why would you have dinner with Michael?”

Her face went pale.

“Because he came back asking for help.”

“What kind of help?”

She hesitated.

“He said Mark was in danger.”

I felt a chill.

“From who?”

“Michael wouldn’t tell me.”

She took a deep breath.

“He only said, ‘You need to believe me. Your husband isn’t the man you think he is.’”
