Who is disturbing my peace? - The Prologue

Greetings, human.
My name is Adelaide McCarthy. I lived around two centuries ago.
But there is someone in my house. Someone I do not know. I should better see what is happening. Who is this?
Does he know the truth? My truth? My chaos, tragedy, loss and pain?
I do not think so.
And I will do everything I can to keep it that way.
Unless...
Unless he could be useful.
And help me with my vengeance.
