I bought the DNA kit to trace my grandfather's village. Two matches came back. One of them carried a surname I had only ever heard in my own jealous nightmares.

I knew one strange fact about the man I suspected. So I sent my spit to a lab and let the math decide whether I was paranoid or right.

She met me at the door with happy tears and a secret she thought would save us. She didn't know the one fact that made her whole story impossible.

She held up the test like a winning lottery ticket. I should have been thrilled. Instead I sat very still, counting backward through a calendar that didn't add up.

My husband couldn't put down a silly little phone pool game with a coworker. I couldn't figure out why a grown man was so obsessed. Then I read between the turns.

A late-night notification from a smart speaker app pinged her phone two hundred miles from home. She only opened it out of habit. Then she pressed play.
