Title: A Killer On the Loose
Rating: Mature
Summary: Starts three weeks after the epilogue at the end of Deathly Hollows. Rolf Scamander and Astoria Malfoy are found brutally murdered and in a compromising position. With a killer on the loose, old enemies will have to work together to find this person and stop them before anybody else dies. Draco/Luna, Harry/Ginny, Ron/Hermione.
Author's Notes: I have gotten into Draco/Luna stories here in the past few weeks and the idea for this story came to me a couple of days ago. I am not normally into non canon pairings but there is something about the thought of Luna and Draco that appeals to me. It will be awhile before anything romantic happens between Draco and Luna, given what is going to their spouses and having to each tell their children what has happened.

Three weeks after seeing her twin sons, Lorcan and Lysander off to Hogwarts for the first time, Luna Scamander returned home a day early from a two week trip to Egypt. She apparated right outside of the front door of the cottage by the sea that she shared with her husband, Rolf.
As she walked into her home, loud screams and moans of pleasure were coming from one of the rooms in her house. Tears filled Luna's eyes when she heard a female voice scream out her husband's name. It was only then that she glanced around the living area of her home and saw clothes, among them a pair of robes she knew belonged to Rolf, scattered on the floor. The trail of them led up to the stairs, past both of her sons bedrooms and right outside of the bedroom that she shared with Rolf.
Luna quietly opened the door and had to fight not to gasp in shock at the sight of her husband making love to Astoria Malfoy in their bed. Before she gave into the urge to pull out her wand and throw a killing curse at both of them, Luna ran down the stairs and out the front door of her home, leaving it standing open. A look of sorrow and heartbreak mixed with one of extreme anger flashed into her big blue eyes and she instantly apparated to the one place that Luna had vowed to never go again. The place where she had been held captive during the war: Malfoy Manor. Because Rolf wasn't the only one in that house who was going to pay for his actions.
As soon as Luna apparated, a man came creeping out of the woods that was less than a mile from her home. He had a hunting knife in one hand and a wand in the other as the man made his way up to the house. The sight of the front door standing open made him stop for a second or two before he finally went inside of the house.
As soon as he got upstairs and saw the two people in the bed, who were so wrapped up in each other that they had not noticed him standing there, a smile of malicious delight came over the man's face.
"Petrificus Totalus" He called out, holding his wand towards man first and then repeated it when the woman started to summon her own wand towards her.
It filled him with an immense pleasure to watch his two victims eyes fill with terror as he stood over them with the knife in his hands. These two would pay with their lives for their adulterous actions.
He swiftly brought the knife down into the man's chest, reveling in the look of pain that came into his eyes and the terror in the woman's. All three of them were covered in Rolf's blood as the knife was swiftly brought down into Astoria's chest. He stabbed them both again and watched as Rolf and Astoria died from their wounds before getting up from the bed and writing a message, in his victim's blood, for the Aurors that were sure to come to investigate these murders.
These were just the first two victims, there will be more!
To the boy who lived: Try to stop me, if you can!
As soon as the man was done writing, he cast a cleaning spell on himself to get rid of the blood, took a photograph and a muggle ink pen out of his pocket, wrote something on it and dropped the picture to the floor. He glanced back at the two people lying on the bed and felt a thrill at the pain their families were about to go through before leaving the house the same way he had left.
AN: This is just the set up for the rest of the story, the next chapters will be longer than this one.
