Disclaimer: I don't own Harry Potter it belongs to the rightful owners. I only own Melissa and any other OCs.

James Potter sat on the couch with his son. Technically the youngest as their son Harry was born twenty minutes after his sister, Harry was a pretty easy baby even at just over a year old. He rarely cried, unlike his sister who cried at little things. His wife Lily was holding Melissa, calming the girl down. He didn't even ask what had set her off this time. James was making lights come out of his wand, entertaining his son.

They heard the gate open and both parents froze. It was almost midnight so there was no way this could be a neighbour or something mundane like that. They started to worry, even though it couldn't be the Dark Lord. He wasn't meant to know where they were, only their friends Sirius Black and Peter Pettigrew knew where they were living with the twins.

"Lily, take the twins and run!" James told his wife, handing her Harry and heading into the hallway. Lily went to hide upstairs in the nursery, taking both twins with her. She heard the front door open and his voice as he used the killing curse on her husband. Lily kept quiet as she heard footsteps move around the house. She tried to think - if she moved from this room he would hear her and she wouldn't be able to run very fast with the twins but she'd never leave her children here alone, especially at his mercy. He had none.

The footsteps were heard again as he approached the staircase. Lily put the twins down in one of the cribs, pulling out her wand and facing the doorway. The door was blasted open and he entered the nursery. He moved towards Harry, the reason he'd come to this cottage. He was here to kill Harry Potter, the boy in the prophecy his follower had told him. He had no quarrel with the other three residents, the prophecy said nothing about the baby girl here just the boy. James Potter had been in the way, but he would leave Lily and her daughter alive if they moved - he'd made an agreement with the follower.
"Lily Potter. Move aside." he told the woman.
"I won't let you kill my children!" Lily glared at the man, moving protectively in front of the crib.
"I only require the death of the boy. The girl may live."
"You won't kill Harry!" Lily pulled out her wand, but before she could cast a spell he had used his.
"Petrificus Totalus." he smirked watching the woman fall to the ground, her body unable to move. He turned to the crib where Harry was watching him. He pointed his wand at the boy. "Avada Kedavra." he watched as the boy fell back into the crib before leaving the room and heading back to his headquarters.

Another visitor entered the cottage, through the open front door. He headed straight upstairs, just knowing where she would be. He entered the nursery, relieved to see Lily was alive and just under a minor spell. He saw the babies in the crib - the girl stood crying while the boy was on his back dead. He knew what would happen if he left the living baby here, his Lily would never speak to him again if her daughter was left here to die or be taken away. He cautiously picked up the baby, who looked up at him with those green eyes so like Lily's. He was relieved when the child stopped crying, instead opting for pulling on his hair and giggling. He used magic to lift Lily's body up and left the cottage with the mother and child.

Nobody knew what had happened to Lily and Melissa Potter. At least, most wizards did not know. Their bodies were never found in that house, only the bodies of James and Harry were recovered. It was a mystery - anyone that knew Lily knew she would never leave one child to save the other and yet only Harry was here.

The truth would not be revealed for eleven years.
