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 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.

I gave my little sister a DNA kit as a gag gift. The results unstitched thirty years of our family in a single afternoon.

He came home from his Saturday run with two coffees and a kiss. I almost didn't read what the barista had scrawled on the side of mine.

I balance our joint account every month out of habit, not suspicion. This time a routine five-hundred-dollar payment to an electrician stopped my hand on the mouse.
