Frankenstein or The Modern Prometheus by Mary Wollstonecraft (Godwin) Shelley
"Yet I fear that the same feelings now exist that made you so miserable a year ago, even perhaps augmented by time. I would not disturb you at this period, when so many misfortunes weigh upon you, but a conversation that I had with my uncle previous to his departure renders some explanation necessary before we meet. Explanation! You may possibly say, What can Elizabeth have to explain? If you really say this, my questions are answered and all my doubts satisfied. But you are distant from me, and it is possible that you may dread and yet be pleased with this explanation; and in a probability of this being the case, I dare not any longer postpone writing what, during your absence, I have often wished to express to you but have never had the courage to begin.
"You well know, Victor, that our union had been the favourite plan of your parents ever since our infancy. We were told this when young, and taught to look forward to it as an event that would certainly take place. We were affectionate playfellows during childhood, and, I believe, dear and valued friends to one another as we grew older. But as brother and sister often entertain a lively affection towards each other without desiring a more intimate union, may not such also be our case? Tell me, dearest Victor. Answer me, I conjure you by our mutual happiness, with simple truth--Do you not love another?
"You have travelled; you have spent several years of your life at Ingolstadt; and I confess to you, my friend, that when I saw you last autumn so unhappy, flying to solitude from the society of every creature, I could not help supposing that you might regret our connection and believe yourself bound in honour to fulfil the wishes of your parents, although they opposed themselves to your inclinations. But this is false reasoning. I confess to you, my friend, that I love you and that in my airy dreams of futurity you have been my constant friend and companion. But it is your happiness I desire as well as my own when I declare to you that our marriage would render me eternally miserable unless it were the dictate of your own free choice. Even now I weep to think that, borne down as you are by the cruellest misfortunes, you may stifle, by the word 'honour,' all hope of that love and happiness which would alone restore you to yourself. I, who have so disinterested an affection for you, may increase your miseries tenfold by being an obstacle to your wishes. Ah! Victor, be assured that your cousin and playmate has too sincere a love for you not to be made miserable by this supposition. Be happy, my friend; and if you obey me in this one request, remain satisfied that nothing on earth will have the power to interrupt my tranquillity.
"Do not let this letter disturb you; do not answer tomorrow, or the next day, or even until you come, if it will give you pain. My uncle will send me news of your health, and if I see but one smile on your lips when we meet, occasioned by this or any other exertion of mine, I shall need no other happiness.
"Geneva, May 18th, 17--"
This letter revived in my memory what I had before forgotten, the threat of the fiend--"I WILL BE WITH YOU ON YOUR WEDDING-NIGHT!" Such was my sentence, and on that night would the daemon employ every art to destroy me and tear me from the glimpse of happiness which promised partly to console my sufferings. On that night he had determined to consummate his crimes by my death. Well, be it so; a deadly struggle would then assuredly take place, in which if he were victorious I should be at peace and his power over me be at an end. If he were vanquished, I should be a free man. Alas! What freedom? Such as the peasant enjoys when his family have been massacred before his eyes, his cottage burnt, his lands laid waste, and he is turned adrift, homeless, penniless, and alone, but free. Such would be my liberty except that in my Elizabeth I possessed a treasure, alas, balanced by those horrors of remorse and guilt which would pursue me until death.
