Days after my triple-bypass surgery, my daughter-in-law kicked my oxygen tank and snarled, “Just choke and die already, old bat. We’re tired of waiting for your estate.” She dug her nails into my bruised shoulder, convinced my “severe dementia” meant no one would believe me. What she didn’t know was that my confusion had been a year-long act. As sirens echoed outside, her face went pale.

“Oops,” Sarah giggled, watching the mask dangle just out of reach.

With a sharp, practiced kick, she sent the silver oxygen tank spinning toward the edge of the landing. It teetered for a heartbeat—a silver cylinder reflecting the moonlight—before plunging over the side. Clang. Clang. Clang. The sound of metal hitting marble echoed through the cavernous foyer like a death knell. It bounced down twenty-four steps, a frantic, rhythmic percussion that ended with a final, hollow thud on the floor below.
