A chill ran down his spine despite the crackling fire in the hearth. Thomas held the letter to the light, the unfamiliar handwriting a stark contrast to the sterile white envelope. It was from his brother, a man he hadn’t spoken to in fifteen years. The years melted away as he read. Memories, sharp and vivid, flooded back: the boisterous laughter, the shared secrets, the abrupt silence that had followed their argument. His hand trembled as he carefully folded the letter, a lump forming in his throat. He leaned back in his chair, the comfort of the fire offering little warmth. The room seemed to expand, filled with the ghosts of yesterday.
