Harry was walking down the corridor, holding a note. Written on it was a single word: “Pipes.” Harry could hear the hissing voice on and off, whispering, “Kill ...”. He kept walking. Just after turning the corner, Harry heard the voice again. He pressed his ear against the wall and listened carefully. Following the sound along the wall, he reached the end of the corridor. Harry pulled out his wand and used the Vanishing Spell to make a brick disappear, revealing the entrance to the Chamber of Secrets. He then went inside.
