“Fear not that I shall be the instrument of future mischief. My work is nearly complete. Neither yours nor any man’s death is needed to consummate the series of my being and accomplish that which must be done, but it requires my own. Do not think that I shall be slow to perform this sacrifice.”
– Mary Shelley
