Her husband's almost home. He'll catch her this time.

There isn't a scrap of curtain, not a blade of blind, in number 212—the rust-red townhome that once housed the newlywed Motts, until recently, until they un-wed. I never met either Mott, but occasionally I check in online: his Linkedin profile, her Facebook page. Their wedding registry lives on at Macy's. I could still buy them flatware.

As I was saying: not even a window dressing. So number 212 gazes blankly across the street, ruddy and raw, and I gaze right back, watching the mistress of the manor lead her contractor into the guest bedroom. What is it about that house? It's where love goes to die.

She's lovely, a genuine redhead, with grass-green eyes and an archipelago of tiny moles trailing across her back. Much prettier than her husband, a Dr. John Miller, psychotherapist—yes, he offers couples counseling—and one of 436,000 John Millers online. This particular specimen works near Gramercy Park and does not accept insurance. According to the deed of sale, he paid $3.6 million for his house. Business must be good.

I know both more and less about his wife. Not much of a homemaker, clearly; the Millers moved in eight weeks ago, yet still those windows are bare, tsk-tsk. She practices yoga three times a week, tripping down the steps with her magic-carpet mat rolled beneath one arm, legs shrink-wrapped in Lululemon. And she must volunteer someplace—she leaves the house a little past eleven on Mondays and Fridays, around the time I get up, and returns between five and five thirty, just as I'm settling in for my nightly film. (This evening's selection: The Man Who Knew Too Much, for the umpteenth time. I am the woman who viewed too much.) I've noticed she likes a drink in the afternoon, as do I. Does she also like a drink in the morning? As do I?
