The photograph felt like a hot coal in her hand. Evelyn had always heard about her great-grandfather’s unwavering devotion to his family. The photo showed him dancing cheek-to-cheek with another woman, a look of pure joy on his face.

Evelyn felt a tremor in her hands. The narrative she’d absorbed all her life seemed to dissolve before her eyes. The silence of the room was overwhelming. She felt a hollow echo inside her, a deep and unyielding void.

She slowly lowered herself to the floor, her back against the cold wall. She felt utterly and completely lost.
