The leather-bound journal lay open on the coffee table. Inside, John's neat handwriting detailed his wife, Emily, in intimate detail. Her morning routine, her favorite flower, her childhood dog’s name, the way she bit her lip when stressed. A wave of nausea surged through him.

He felt rooted to the spot, unable to move, his muscles frozen. He wanted to scream, to lash out, to demand answers. But the words caught in his throat, a silent scream trapped within him. He felt an intense pressure building behind his eyes.
