“ then things got even stranger.Mr. Brunner, who'd been out in front of the museum a minute before, wheeled his chair into the doorway of the gallery, holding a pen in his hand. What ho, Percy! he shouted, and tossed the pen through the air.Mrs. Dodds lunged at me.With a yelp, I dodged and felt talons slash the air next to my ear. I snatched the ballpoint pen out of the air, but when it hit my hand, it wasn't a pen anymore. It was a sword-Mr. Brunner's bronze sword, which he always used on tourement day.Mrs. Dodds spun toward me with a murderous look in her eyes.My knees were jelly. My hands were shaking so bad I almost dropped the sword.She snarled, Die, honey!And she flew straight at me.Absolute terror ran through my body. I did the only thing that came naturally:I swung the sword.The metal blade hit her shoulder and passed through her body as if she were made made of water. Hisss!Mrs. Dodds was a sand castle in a power fan. She exploded into yellow powder, vaporized on the spot, leaving nothing but the smell of sulfur and a dying screech and a chill of evil in the air, as if those two glowing red eyes were still watching me. ”
