I rolled down my window, thrust my arm out, and pointed straight at Cecil in the truck beside me.

"Cecil, you son of a bitch! You're killing him!"

Cecil sat in the driver's seat and glanced toward my back seat. A flicker of surprise crossed his face.

Then it was replaced by pure, gleeful satisfaction.

His message came through a moment later.

"Ha! My own father never even slapped me, but you had the nerve to. Now your old man's dead, isn't he?"

"Karma. That's what this is. Karma!"

I freed one hand, steadied my phone, and snapped a photo of my father-in-law crumpled in the back seat. I sent it straight to my wife.

"Gretchen! Get it through your head. I am trying to get our father to a hospital. I am driving to save his life!"

Her expression on the screen was dark as a storm. She reached across her car, rummaging for something, then rolled down her window and extended her arm.

A steel wrench glinted in her fist.

I realized what she was about to do.

My heart seized. I screamed, frozen in place.

"Gretchen, no!"

The next instant, her fingers unclenched. The wrench hurtled through the air and slammed into my windshield.

A deafening crack.
