Imagine if you will, that you have an older brother.
He's an admirable kind of brother, the same as your parents. He has an interest in the natural sciences and is a bit of a nerd, but he's a great brother. Alongside your older brother, of course you have your parents, a younger brother (who is practically an angel to everyone who has ever known him), a cousin who is sort of your sister (and also your brother's one true love or whatever), your older brother's lifelong best friend, and a servant girl who is practically family.
Life is easy. You live everyday with great pleasure in your native home where the icy-capped mountains are beautiful and the lake serene.
Of course, like any other human being, you experience a great tragedy. One day, your cousin-sister gets sick. In her kindness, your mother takes care of her but gets sick herself and dies. It's tragic... but it happens.
Afterwards, your older brother leaves for university, and you spend your life full of enjoyment. The only thing you wish is that your father would allow you to take leave and become a soldier. Unlike your older brother, you had no fondness for the academia and would rather go out and find glory in battle.
In this time, your older brother's letters begin to slowly dwindle, that almost two years have gone by since his last writing. It bothers you, but as you are just a youth, it doesn't bother you as much as it does your father, your cousin-sister, and your older brother's best friend (who eventually does leave to go to the same university as your older brother).
From your brother's best friend, you're informed that your brother has gotten ill, but at least his best friend is there to care for him. Gradually, your brother begins to write to your family again and all seems well.
One day, you go out with your family to enjoy the nature. You and younger brother go out into the forest to play hide and seek. You seek, but do not find. You return to your family, hoping your brother went back but he didn't. You and your family try to find him for the entire night.
In the morning, you find him murdered.
A part of you blames yourself. After all, you were the last to see him. Maybe you even proposed that game of hide and seek. Maybe if you hadn't lost him he'd still be alive. Your older brother is told to come back home, and while waiting for him, you find out that your family's servant (who your family has loved like their own) was the murderer.
It's all so strange and horrible, but her trial is set, and your older brother has come home. He is visibly shaken when you first meet him after many years apart. He's changed, but he's still your brother. He raves a bit to you about how he knows who the murderer is, but instead of the servant, he mentions some other fiend.
This thought is quickly swept away by the ensuing trial and execution of someone you once held dearly. Your older brother is so distraught. He has decided to stay home, but his misery is palpable and you feel sorry for him, your father, your cousin-sister, and yourself. Although, you try your best to be happy.
Months past, your older brother has returned from a trip to some neighboring cities. Your father has been casually mentioning the possible marriage between your older brother and your cousin-sister. Instead of agreeing immediately, as you thought he would, your older brother instead decides to go to England with his best friend. Which is really strange to you, but hopefully he comes back better.
A year nearly passes... your older brother's best friend is dead and your brother has been accused of his murder. Your father has to travel all the way to Ireland to save him. Eventually they return, and your brother is a wreck - though that's to be expected after the murder of his best friend. Still, he decides to go on with the marriage - and there is happiness in your household once again.
Though somehow, your ever unlucky brother sails away with his new wife... and comes back stating that she has been murdered. The news literally kills your father, leaving you and your brother alone.
The next few months are torture as you watch your brother turn into a shell of himself, further falling into the miseries that you have both suffered. However, somehow a part of you can tell that there's something deeper in his despair, though you can't exactly know what.
Then you hear from a magistrate about your older brother's ravings about that fiend... the murderer he'd once mentioned a long time ago. The talks of a madman.
Your older brother leaves, promising to kill whoever enemy he had conjured up in his mind.
He's gone for months... maybe even years.
He comes back dead, though not alone. His body escorted by a ship captain.
He has a tale to tell you.
Oh, btw, your name is Ernest Frankenstein.
