I canceled my ex-mother-in-law’s credit card the moment the divorce was finalized—and when my ex called, furious, I finally said everything I had kept bottled up for years. “She’s your mother, not mine. If she still wants quilted Chanel bags from Fifth Avenue, figure out how to pay for them yourself.”

I threw off the duvet, my bare feet hitting the cold hardwood floor. I didn’t bother reaching for a robe to cover my silk pajamas. I walked with slow, deliberate steps down the hallway toward the foyer.

“I know you are in there, Marissa! Open the door!” Eleanor’s voice had pitched into a shrill, manic screech, completely devoid of the faux-aristocratic restraint she normally projected.

I reached the front door and silently pressed my eye against the brass peephole.

The fisheye lens distorted the hallway, but the image was agonizingly clear. Eleanor Whitford was standing inches from the wood, her face flushed an ugly, mottled crimson. She was immaculately dressed in a tailored cream trench coat and an authentic Hermès silk scarf, her hair perfectly coiffed, but her eyes were wild and feral.

Hovering just behind her right shoulder, shifting uncomfortably from foot to foot, was Anthony. He wasn’t pounding on the door. He wasn’t yelling. He was simply standing there, clutching a leather briefcase, projecting the aura of a cowardly man using his mother as a human shield.

Further down the hall, I saw the heavy mahogany door of apartment 4B crack open. Mr. Henderson, an elderly retired judge who served on the building’s co-op board, peeked his head out, his expression registering a mixture of profound shock and deep disapproval. Other doors were likely unlocking, an audience gathering to witness the impromptu circus.

Eleanor raised her fist to strike the door again.

I reached up and slid the heavy, brass security chain securely into its track. Then, I turned the deadbolt and pulled the door open exactly three inches. The heavy chain snapped taut, halting the door’s momentum.

Eleanor’s fist froze in mid-air. She lowered it, her eyes flashing with a predatory, triumphant gleam as she stared at me through the narrow, vertical gap.
