"Okay," Murphy said. "Getting out of here is good."
"I bet the bad guys are counting on that, trying to flush us out into a dark alley. You carrying?"
Murphy was already drawing her gun from under her jacket, a well-used military-issue Colt 1911. "Are you kidding?"
I noticed that her hands were shaking. "New gun?"
"Old reliable," she said. "You told me magic can jam a flaky gun."
"Revolver would be even better."
"Why don't I just throw rocks and sharp sticks while I'm at it, Tex?"
"Auto bigot." I spotted an EMPLOYEES ONLY sign. "There," I said, and went that way. "Out the back."
We headed for the swinging doors under the sign. I hit them first, shoving them open. A grey wall of mist lay in front of me and I leaned back, trying to stumble to a halt. If I let myself touch the mist, I might not have enough of my wits left to regret it. I stumbled a foot short of it and almost fell forward, but Murphy grabbed my shirt and jerked me sharply back.
We both backed out into the store. "Can't get out that way," Murphy said. "Maybe they don't want to herd you anywhere. Maybe they just want to gas you and kill you while you're down."
I swept my gaze around the store. Cold grey mist rolled forward, slow and steady, in every direction. "Looks like," I said. I nodded down a tall, narrow aisle containing auto parts. "Down there, quick."
"What's down here?" Murphy asked.
"Cover. I have to get us a defense against that mist." We reached the open space at the end of the aisle, and I nodded to Murphy. "Here, stop here and stand close to me."
She did it, but I could still see her shaking as she asked, "Why?"
I looked up. The mist had reached the far end of the aisle and was gliding slowly down it. "I'm going to put up a circle that should keep it off us. Don't step out of it or let any part of you cross outside."
Murphy's voice took on a higher, more tense pitch. "Harry, it's coming."
I twisted open both salt shakers and started pouring them out in a circle around us, maybe three feet across. As I finished the circle, I invested it with the slightest effort of will, of intent, and it closed with a sudden snap of silent, invisible energies. I stood up again, holding my breath, until the mist touched it a moment later.
It roiled up against the circle and stopped, as though a cylinder of Plexiglas stood between it and us. Murphy and I both let out our breath in slow exhalations. "Wow," she said quietly. "Is that like a force field or something?"
"Only against magical energies," I said, squinting around us. "If someone comes along with a gun, we're in trouble."
"What do we do?"
"I think I can protect myself if I'm ready to do it," I said. "But I need to set up a charm on you."
"A what?"
"Charm, short-term magic." I fumbled at my shirt until I found a frayed thread and started pulling it out. "I need a hair."
Murphy gave me a suspicious frown, but she reached under her hat and unceremoniously jerked out several dark gold hairs. I plucked them up and twisted them together with the strand of thread. "Give me your left hand."
She did. Her fingers shook so hard that I could feel it when I put my own around them. "Murph," I said. She kept looking up and down the aisle, her eyes a little wild. "Karrin."
She looked up at me. She looked very young, somehow.
"Remember what I said yesterday," I said. "You're hurt. But you'll get through it. You'll be okay."
She closed her eyes tightly. "I'm scared. So scared I'm sick."
"You'll get through it."
"What if I don't?"
I squeezed her fingers. "Then I will personally make fun of you every day for the rest of your life," I said. "I will call you a sissy girl in front of everyone you know, tie frilly aprons on your car, and lurk in the parking lot at CPD and whistle and tell you to shake it, baby. Every. Single. Day."
Murphy's breath escaped in something like a hiccup. She opened her eyes, a mix of anger and wary amusement easing into them in place of the fear. "You do realize I'm holding a gun, right?"
"You're fine. Hold your hand still." Though her fingers still trembled a little, the wild, panicked spasms had ceased. I wrapped the twist of hair and thread around her finger.
Murphy kept on peering through the mist, her gun steady. "What are you doing?"
"Enchantment like that mist is invasive," I said. "It touches you, gets inside you. So I'm setting you up with a defense. Left side is the side that takes in energy. I'm going to block that mist's spell from going into you. Tie a string around your finger so you won't forget."
I tied the string in an almost complete knot, so that it would need only a single tug to finish. Then I fumbled my penknife out of my pocket and pricked the pad of my right thumb. I looked up at Murphy, trying to clear my thoughts for the spell.
She regarded me, her face pale and uncertain. "I've never really seen you, you know. Do it. Before."
"It's okay," I told her. I met her eyes for a dangerous second. "I won't hurt you. I know what I'm doing."
She lifted the corner of her mouth in a quick smile that made her eyes sparkle. She nodded and returned to peering out through the mist.
I closed my eyes for a moment and then began gathering my focus for the spell. We were already within a circle, so it happened fast. The air tightened on my skin, and I felt the hairs along my arms rise as the power grew. "Memoratum," I murmured. I tied off the improvised string and touched the bead of blood on my thumb to the knot. "Defendre memorarius."
The energy rushed out of me and into the spell, wrapping tight around the string and pressing against Murphy. A wave of goose bumps rippled up her arm, and she drew in a sudden sharp breath. "Whoa."
I looked at her sharply. "Murph? You okay?"
She blinked down at her hand, and then up at me. "Wow. Yeah."
I nodded, and took my pentacle out of my shirt. I wrapped it around my left hand, leaving the five-pointed star lying against my knuckles. "Okay, we're pushing our luck enough. Let's hope this works and get the hell out of here."
"Wait, you don't know if it will work?"
"It should work. It ought to. In theory."
"Great. Would it be better to stay here?"
"Heh, that's a joke, right?"
Murphy nodded. "Okay. How will we know if it works?"
