Hell Hath no fury like a woman scorned.
Emelia Ricoletti, white as death, mouth like a crimson wound. She came back from death in her bloody wedding dress to avenge her torments. One shot and her husband hit the ground, she disappeared in the fog; becoming an avenging ghost.
M.Holmes is the British government, though he seems to be overthrown by an invisible army. Contacting an old friend, he backs down and lets his younger brother discover for himself the silent revolt forming.
