Chapter 1 — Today You Stop Being My Wife

“Today you are going to stop being my wife, and I want everyone here to witness it.”

My husband said those words at his mother’s seventy-fifth birthday party, in front of more than a hundred guests, in the ballroom of an exclusive country club in Greenwich, Connecticut.

I was standing beside his mother when he said it, adjusting the soft cardigan across Eleanor’s shoulders while the catering staff moved down the tables pouring champagne.

Joe had been gone from the room for almost an hour by then, and I already knew why, because I had known for three days exactly what my husband was, and had been waiting, with a terrible patience, to find out how he would choose to show the rest of them.

So when his voice came across that beautiful room, I did not flinch.

I finished settling the cardigan on Eleanor’s shoulders.

I set down the champagne flute I’d been holding for her.

And I turned, slowly, to face the man I had been married to for ten years, and I thought, with a calm that surprised even me: all right, Joe.

Let’s see how far you’ve decided to take this.

Because the thing my husband did not know — the thing that would, within the next ten minutes, turn his carefully staged humiliation of me into the ruin of his own life — was that our ten-year-old son had gotten there first.

Chapter 2 — The Burner Phone

Three days before the party, I had found the second phone.

It was in the back of the bottom drawer of his study desk, behind a box of old business cards, a cheap prepaid thing that was not the phone I knew about, and I want to tell you that I did not go looking for it, that I stumbled onto it, but the truth is I had felt something wrong in my marriage for a long time, the way you feel weather in a bad knee, and some part of me had been looking for months without admitting it.

The phone was not even locked.

That is how little he feared discovery, how thoroughly he had come to believe I would never dare.

There were photographs.

There were messages, hundreds of them, going back more than three years.
