Thomas Shelby sees ghosts, many and varied. The ghosts of his mistakes, the ghosts of the war, but the one he sees most clearly is her, his childhood friend, the one who was his ray of sunshine, the one who would have overshadowed his love for Grace if she had been alive Her ghost was always with him, because he couldn't let her go, he wore a small silver pendant with her photo in his watch pocket, always there, always on the left side of his heart.
