A novel by

 
 
Dark psychological thriller featuring a wife who isn't who she used to be, a husband who's done this before, and a marble staircase that remembers everything.

He came home from six weeks overseas. She was waiting. So was the truth.

My husband is charming, successful, and adored by everyone who meets him. He built his life from nothing — or that's the story he tells. The beautiful house. The corner office. The Italian marble staircase he loves more than anything in it.

I've been the perfect wife for twenty-two years. I know how he takes his coffee. I know which tie he wears to impress clients. I know about the woman he keeps in a condo across town.

And now I know about the other wife. The first one. The one who fell.

He thinks I don't see him clearly. He thinks none of us do. He's wrong about that. He's wrong about a lot of things.

Then one morning, someone is lying at the bottom of the marble staircase. And nothing — not the wife, not the husband, not a single word you've read to this point — is what you think it is.
