Grum got hold of Murphy's foot and started dragging her back toward him. She let out a hollow gasp, then twisted and wriggled. She slipped out of her sneaker and hauled herself away from the ogre, her face gone white and drawn.

I ran up behind Grum, pulling my left hand out from behind my back, the fingers of my right hand still curled around the flickering flame I'd shown the ogre. A large yellow-and-green pump-pressure water gun sloshed a little in my left fist. I lowered it and squeezed the trigger. A stream of gasoline sprayed out all over Grum's back, soaking the ogre's skin. Grum whirled toward me halfway through, and I shot the gasoline into his eyes and nose, eliciting another scream. He bared his fangs and glared at me through eyes swollen almost shut.

"Wizard," he said, hardly understandable through the fangs and the drool, "your spellflame will not stop me."

I turned my right hand slowly, and showed Grum the burning can of Sterno I'd been palming. "Good thing I've got this plain old vanilla fire, then, huh?"

And I tossed the lit can of Sterno onto the gasoline-soaked ogre.

Hamstrung and blazing like a birthday candle, Grum screamed and thrashed. I skipped back and around him, helping Murphy up to her feet as the ogre slammed himself against the ground and then against the back wall of the Wal-Mart. He did that in a frenzy for maybe twenty seconds, before uttering an odd, ululating cry and hurling himself at a deep shadow behind a trash bin-and vanished, the light from the flames simply disappearing.

Murphy got up only with my help, her face pale with pain. She could put no weight at all on her wounded leg. "What happened?"

"We whipped him," I said. "He packed up and headed back to Faerie."

"For good?"

I shook my head. "For now. How's your leg?"

"Hurts. Think I broke something. I can hop on the other one."

"Lean on me," I said. We went a few paces, and she swayed dangerously. I caught her before she toppled. "Murph?"

"Sorry, sorry," she gasped. "Hopping, bad idea."

I helped her back down to the ground. "Look, stay here, against the wall. I'll get the Beetle and pull it around here to you."

Murphy was in enough pain to keep her from arguing. She did draw her gun, switch the safety on, and offer it to me. I shook my head. "Keep it. You might need it."

"Dresden," Murphy said, "my gun has been about as useful as fabric softener in a steel mill tonight. But someone out there has a rifle. If they're using one, it's because they're a human, and you don't have most of your magic stuff with you. Take the gun."

She was right, but I argued anyway. "I can't leave you defenseless, Murph."

Murphy hauled up the leg of her jeans and pulled a tiny automatic from an ankle holster. She worked the slide, checked the safety, and said, "I'm covered."
