The phone on the nightstand didn’t just ring. It buzzed and vibrated against the dark wood grain of the table at exactly 11:23 P.M., slicing through the quiet house like a dropped glass. I lay there in the dark for three seconds, listening to the harsh, rattling hum of the screen light up the empty bedroom. The name flashing across the glass was Mark. Not an unknown number, not a debt collector, but the man who had vanished from my life two weeks after handing me a stack of court papers in a sterile hospital gown. I reached out, my fingers wrapping around the cold plastic, and pressed accept without a single second of hesitation.
