Harry Potter and the Chamber of Secrets - Pg 310

"Dear Tom, I think I'm losing my memory. There are rooster feathers all over my robes and I don't know how they got there. Dear Tom, I can't remember what I did on the night of Halloween, but a cat was attacked and I've got paint all down my front. Dear Tom, Percy keeps telling me I'm pale and I'm not myself. I think he suspects me.... There was another attack today and I don't know where I was. Tom, what am I going to do? I think I'm going mad.... I think I'm the one attacking everyone, Tom!"
