Chapter One:

He was my brother

Sirius Black was my brother, my real biological brother. I was his younger sister but disregarding the age I felt the need to protect him. My mother disowned me not long after she did so with Sirius. When he ran away I felt as if he abandoned me. That turned out not to be the case. He still wrote to me whenever he could, but mother never knew. Mother would kill me if she did. She did find out after a while. It was the night Sirius came to visit. It was after midnight and Mother went to bed ages ago, so when I seen the red sparks outside my window I ran for the door. Without thinking to check if that rat of a house elf was lurking nearby. Within minutes of me letting Sirius in Mother came bursting into the hall, wand out, and Kreacher at her heels. He snitched. That night mother throw both me and Sirius out and told us never to set foot in her house again. Now with the last of her children gone she was left by herself.

I did stay with Lily and James for sometime till I found a home of my own with Sirius. Lily and James Potter were close friends of Sirius so I relied on them for anything, they swore to help in anyway they could. I was there that night when Sirius argued with James about setting Peter Pettigrew as Secret Keeper for them, explaining " They'll never suspect you to use him," of course he was referring to the Death Eaters who were at large since at the time Voldemort was a great fear in the wizarding world. I was there with Sirius when he received the word that Lily and James were dead and Harry survived. Voldemort had killed James first, then Lily, who stood up to him trying to protect little Harry, but she too was killed, no remorse what-so-ever. Then Voldemort turned on Harry, just a year old, a baby at the time, and tried to kill him as well but was unsuccessful. The curse backfired and Voldemort disappeared. No one knows what happened that night, literally what went wrong and where He-Who-Must-Not-Be-Named has gone. He surely couldn't be dead could he?

Then Sirius made his plan: To kill Peter Pettigrew.

" Sirius, please, don't. I will take care of it." I pleaded. I would do it, no one knew I was Sirius sister. Even those who knew me then wouldn't know now, I easily solved that issue. I haven't looked like myself in years. I had a secret, I was a Metamorphmagus. I could change my appearance at will. No one besides Dumbledore and Sirius knew what I was. So, going through with doing Sirius's evil deed would basically be no harm to me. My pleading though seemed unnecessary.

By the look on his face I couldn't convince him otherwise. The look of rage on his face scared me, he looked as if he could kill me. "Don't tell me that rubbish about you being able to take care of it, Melissa. You know better then I do that you wont, you can't. Fearing them, they wont let you near him. They would be outraged to know you where here now. If they knew they'd surely kill you wouldn't they?" he questioned.

"Yes." I whispered through my teeth.

"Then how could you possibly take care of it? How will you kill Peter with all them watching you like a hulk?" he demanded.

"They wont be watching me, don't you see Sirius, they are all either trying to convince everyone they were bewitched or running for it. The Dark Lord isn't here to protect them from the Ministry anymore. They can't win. They wont be watching me." I repeated again.

"Lets say they are watching you, what makes you think they wont turn on you, huh? Just because you were Voldemort's little pet doesn't mean anything to them. Like you said they didn't like you, they didn't even trust you even though there Master reminded them you were the loyalist of them all. Apparently they didn't know Peter was working for us, but to only find out that Peterwas really passing useful and true information onto Voldemort. He didn't confine in you that he had another reliable source of information too. What makes you think they believe him about you? Supposedly Peter was the most loyal to him." Sirius looked more angry then ever. "What makes you think they wont kill you when you walk through the door back to them tonight?"

"They wont kill me." I said rather loudly.

"And how can you be so sure?"

"The Malfoy's wont allow it." I said truthfully.

They wouldn't let the others kill me. They knew I was most faithful to the Dark Lord. They would believe anything I told them. Even my lies. They'd shield me, keep me from Death. Narcissa wouldn't allow them to kill me, she cared for me, as a sister. Whatever Cissy wants she gets no matter what it is, Lucius Malfoy wont disappoint his loving devoted wife. No one besides the Order knew I was in contact with Sirius , no one knew that I secretly was working on orders from Dumbledore to get inside the close knitted world of the Death Eaters, a mission for the Order of the Phoenix.

"You believe me don't you Sirius? About them? They wont let them harm me." I now stood in front of Sirius, searching his eyes for any sign of understanding.

"You wouldn't be alive today if they didn't think so." he finally said, a guilty look crossed his face.

Sirius believed it was his duty with being the older brother is to protect his younger sister from danger. He feels I shouldn't be involved in any of this. Wishes that there was something he could do to change it.

"Sirius, I swear, if you honestly believe me please let me take care of this myself. There's no need to risk your freedom for this." I pleaded again.

"My freedom? I don't have freedom Melissa. Don't you get it, I'm hiding from the Ministry as we speak, they believe I turned Lily and James over to Voldemort. They are looking for me, to haul me to Azaban, so why not do this myself? I would be hauled off to Azaban no matter what anyway. Why not do something worth being sent there for?"

"Because this isn't your fault, its mine."

"Your fault? How'd you come up with that one?" he bellowed, angry again that I was making this so hard, when me fighting him wasn't needed.

"I should have known, Sirius, known that Peter was a sneaking, lying, deceiving little scum I always believed he was. I only let that point of view pass because you and the others believed in him." I began to cry again. "Its my fault that Lily and James are dead today."

"If its anyone's fault its mine. I should have never convince them to change Peter to Secret Keeper at the last moment. There dead because of me."

He walked away from me over to the fire and stared into for sometime before speaking again.

"Melissa, I have to do it. I cant risk anything happening to you. I swore to protect you since the day you were born." he said softly.

"But Sirius--" I began, pleading in my voice once again.

" Like you said you wont be in danger with the Malfoy's, then don't make them think twice about you. I have to do this. My last forgiving act to Lily and James."

There was no way to convince him. No matter how hard I tried there was no stopping him. Even if he agreed to let me kill Peter myself, as soon as I turn my back on him he'd do it himself. So what was the time wasted on arguing with him. I was basically wasting my breathe for a lost cause.

"Okay," was all I said.

"That's it, you'll let me take care of this, Melissa?" he sounded slightly shocked with me giving in.

"Yes. You can do it. You wouldn't let me take care of it even if you'd agreed. You'd do it as soon as I turned my back." I smiled slightly.

"Yeah, your right about that." he grinned back.

"I love you, Sirius. Remember that, whatever might happen, your my brother and I love you. Always." I whispered as tears began to roll down my face more heavily the before.

He pulled me to him, hugging me tightly as if he was never going to let go. As if he felt a bigger separation or danger on the horizon that was bound to come no matter what our decision was. Then he said "I love you, too."
