The day my son was born should have been the happiest day of my life.

Instead, it became the beginning of the biggest mistake I’d ever make.

My wife, Emily, had just delivered a healthy baby boy after nearly twenty hours of labor.

My parents cried.

Her parents hugged each other.

The nurses congratulated us.

But one thought refused to leave my mind.

The timing.

Months earlier, Emily had gone on a weeklong business conference while our marriage was going through a rough patch. We’d argued constantly, and I’d let suspicion grow inside me.

Friends planted ideas in my head.
