Mrs. Norris was patrolling the lonely corridors as usual. She was hated by most students, but that didn't matter. Mr. Filch adored her.
Mrs. Norris scanned the dark corridor one last time, and turned on her paw. It was very wet, the floor. She would go back to Mr. Filch and report that everything was clear tonight. Expect for the flooding water. He didn't like wondering students at night when they should be in bed.
She went around the corner of the hall, and saw something weird on the wall. Mrs. Norris was a strange type of cat, so she could perfectly understand what it said. The Camber of Secrets has been opened. Enemies of the Heir, Beware. Chamber of Secrets had been opened. Enemies of the Heir beware.
Mrs. Norris jumped back a little to look at it clearly. She then went closer to sniff it. It was blood.
She sprinted down the corridor for Mr. Filch, but she was too late. The last thing the poor cat saw was a pair of big yellow eyes in the reflection of the water.
Mrs. Norris wouldn't be able to patrol the corridors for a while now.
