A shy knock came from the door. It sprang open upon a dismissive gesture of his hand. Sitting with his back to the door, he did not see the slender feminine form clad in a furry cloak with matching hat and boots. He saw neither the hurt expression on her face nor the travel bag she carried.
"Narcissa, what do you want?" , he sounded annoyed. Of course, this was his study; he had work to do. "You are asking what I want?", she huffed indignantly, "I want nothing of you anymore. You are so full of yourself; it makes me sick. May you experience this same sickness someday. I'm leaving Lucius and I will take Draco with me"
She waited a moment, secretly hoping that he would miraculously turn around and beg for her to stay, promise betterment but he did no such thing. Well; he turned around but his words were full of disgust and hatred: "So, you are leaving me? Then get the hell out of my house and remove this monster from my life!"
His words were lost on the empty door frame, his wards informing him that she had just apparated. With her his fury had vanished, leaving him in shock of what had just happened. She had left him. She has left you. She left me. She... His thoughts were chasing one another. Two decades of marriage and here he was alone, with no apt heir to all the materialism around him. No one who cared for him. He felt empty.
Mechanically his hands wandered to the heavy desks drawer and pulled out a bottle of fire-whiskey. Forgoing a glass, he took a swig from the bottle. The smokey aroma burnt down his throat. It had been a while that he had tasted whiskey. Usually he preferred wine. This situation however, called for a stronger beverage.
He had suspected that she was cheating on him for a while now. Ever since the war she was tiptoeing around him, not to be found at the house for hours without leaving a note. Defending the shame of what had once been his spouse. The hut in the darkest corner of the grounds with its heavy wards and fences was built on her insistence. Killing the danger to himself and others was the preferred solution of Lucius to the 'werewolf-problem'. He could not view this foul creature as Draco. His son had died when Fenrir Greyback had bitten him. And that was the official story.
Now there would be no traces of the bodies remnants. Narcissa had to make an unbreakable vow to him, as had this monster. Once they revealed him, both would be dead. A grim smile played around his lips. Yes, he had known it all along and patted himself on his shoulder for his foresight. The marriage contract between him and Narcissa would ensure that she got nothing of his and pay for her mistake. The wolf would never be linked with him again, Severus potions heritage had done wonders. The creature was unrecognizable. He had prepared and cleaned up nicely. He did not need these parasites. They had needed him.
In fact Narcissas departure opened new doors: as pretty as the witch admittedly was, she was uncapable of bearing another child for him, leaving him without a heir. Now that she had discredited herself, he was free to find himself a new witch more befitting for him and his needs. He stoppered the bottle not having drunk another sip after the initial one. Enough of his musing. There was no use in wasting thoughts to her. It was time to celebrate this new beginning...
