Then got to work first crossing off anyone who was at the school. A for Away H for Here

Hannah Abbott = H
Mandy Broklechurst =  H
Millicent Bulstrode = H
Terry Boot = H
Vincent Crabbe =  A
Alanah Cragg = H
Monty Cragg = H
Justin Flinch-Fletchley  = H
Semus Finagan = A
Gregory Goyle = A
Hermione Granger  = A
Neville Longbottom = H

Draco Malfoy = A

Jacob Nott =  A
Pancy Parkinson = H
Padma Patil = A
Parvati Patil = A
Harry Potter = H
Dean Tomas = A
Ronald Weasly = H
Blaise Zabinni = H

I went back through the list putting M for mean to them, F for friend and N for neither

Hannah Abbott = H = N
Mandy Broklechurst = H = N
Millicent Bulstrode = H = M
Terry Boot = H = N
Vincent Crabbe = A = M 
Alanah Cragg = H = F
Monty Cragg = H = F
Justin Flinch-Fletchley = H = N
Semus Finagan = A =N
Gregory Goyle = A = M
Hermione Granger = A = F
Neville Longbottom = H = N

Draco Malfoy = A = M

Jacob Nott = A = N
Pancy Parkinson = H = M
Padma Patil = A = N
Parvati Patil = A = N
Harry Potter = H = F
Dean Tomas = A = N
Ronald Weasly = H = F
Blaise Zabinni = H =N

I narrowed the list to all the M's.

Millicent Bulstrode = H = M

Vincent Crabbe = A = M 

Gregory Goyle = A = M

Draco Malfoy = A = M

Pancy Parkinson = H = M

I then removed those who were Here at Hogwarts when the letter that arrived over Christmas.

Vincent Crabbe = A = M

Gregory Goyle = A = M

Draco Malfoy = A = M

I was left with three people two of which were to dumb to do anything like this the other was exactly the kind of person who would. Thinking back on everything it made sense. It had to be Malfoy. I got up and went back to see Headmaster Dumbledore. I showed him the evendince and he said he would look over everything and I left going back to my bedroom to bed but I could not sleep. Who knew what Malfoy was planing next....
