The ice on the back porch glistened like broken glass under the security lights.

The winter air was sharp enough to sting my throat with every breath.

Derek stood in the doorway, his chest rising and falling beneath his charcoal cashmere sweater.

“You’re not listening to me, Monica,” he said.

His voice was quiet, which was always more dangerous than when he shouted.

I stepped back, but my leather boot caught on the frozen edge of the welcome mat.

He didn’t yell when he reached out and shoved my shoulder.

The wood of the deck was slick, and my feet swept out from under me instantly.

I landed hard on my left side, my arm trapping beneath my weight on the frozen planks.

The sound of the bone snapping was loud in the quiet suburban night.

It sounded like a dry branch cracking in the woods.

I couldn’t breathe for a few seconds as the cold air rushed out of my lungs.

“Get up,” Derek said, looking down at me from the warm threshold of the kitchen.

“I think it’s broken,” I whispered, clutching my left wrist to my chest.

“Don’t be dramatic,” he said, stepping back into the warmth.

He checked his watch, a gold piece he bought himself for his thirty-ninth birthday.

“My forty-person dinner is in five days, Monica.”

“I need you presentable, and I need this house immaculate.”

“Do you understand me?”

He shut the sliding glass door and locked it, leaving me in the freezing air.

I managed to stand up using only my right hand, pressing my back against the siding.

The pain in my arm was a cold, sharp blade.

At the emergency room, I told the young doctor I slipped on the driveway while carrying groceries.

They put a heavy fiberglass cast on my left forearm.

When I came home, Derek was asleep in the master bedroom, his breathing heavy and even.

I sat on the living room sofa in the dark, staring at the polished granite of the kitchen island.

I had five days to prepare for forty of his business executives and their spouses.

My left arm was entirely useless.
