finds amulet

"Argh, I'm an idiot," I said. I leaned my still-glowing staff against the bike and jerked the silver amulet off my neck. "My mother left this to me. Thomas has one like it. She had forged a link between them so that when one of us was touching both of them we got a... sort of a psychic voice mail."
"Meaning what?" Murphy asked.
I twisted the chain around the index finger of my burned hand, letting it dangle. "Meaning I can use that link to find the other amulet again."
"If he has it," Murphy said.
"He will," I said. "After last night, he won't take it off."
"How do you know that?"
"Because I know it," I said. I held my right hand palm up and tried to focus upon it. I found the link, the channel through which my mother's latent enchantment had contacted Thomas and me, and I poured some of my will into it, trying to spread it out. "Because I believe it."
The amulet quivered on its string and then leaned out toward the night to our left.
"Stay close," I said, and turned in that direction. "Okay, Murph?"
There was no answer.
My instincts clamored in alarm. I dropped my concentration and looked around, but Murphy was nowhere in sight.
Directly behind me there was a muffled sound, and I turned to find Lord Raith standing there with an arm around Murphy's neck, covering her mouth and with a knife pressed up hard against her ribs. He was wearing all black this time, and in the autumn moonlight he looked like little more than a shadow, a pale and grinning skull, and a very large knife.
"Good evening, Mister Dresden."
"Raith," I said.
"Put the staff down. Amulet too. And the bracelet." He pressed the knife and Murphy sucked in a sharp breath through her nose. "Now."
Dammit. I dropped the bracelet, the staff, and my amulet to the grass.
"Excellent," Raith said. "You were right about Thomas keeping his amulet with him. I found it around his neck when I was cutting his shirt off to have him chained down. I was fairly certain that you would judge such an obviously linked item to be too hazardous to employ in any location magic, but on the off chance I was wrong, I kept my own location spell going. I've been watching you since you arrived."
