Ok, just a quick clarification. In the first part, Draco states in the letter that his father is in Azkaban. He was. But the night Draco fled, he got out. I actually made a mistake in the first part, I didn't mean to say he was in Azkaban, but I fixed it :D
Narcissa Malfoy knocked hard on a large wooden door. A man with greasy, shoulder length hair opened the door.
"Severus, I need your help. Draco ran away tonight, and Lucius refuses to help me find him. I'm just so scared, I didn't know where else to come!" she cried. The man called Severus led her into a large, dusty sitting room.
"Just calm down Narcissa" he said silkily, "and tell me everything". Narcissa explained everything; the letter, what it had said, Lucius's reaction, everything.
"Please, Severus" she said, grasping her hand, "You have to help me" Tears rolled down her pale face. Severus stood up and walked over to a window.
"The only thing I could do" he started. "Would to be use Occlumency against Draco. I cannot gurantee this will work, as he might be far away. I, however, can try. I believe you know how it works?" He asked Narcissa, who nodded.
"Very well. Just give me a moment" he said. He sat down and closed his eyes. A look of deep concentration came over him. Narcissa watched him intently.
"He is with Blaise Zabini" he said finally. Narcissa stood up.
"Thank you Severus, I don't know how I could ever repay you" she said. And with another loud crack, she was gone.
That looked a lot longer when I wrote it on paper. Ah well
