instincts vs grimalkin

I hadn't been following the little faerie for five seconds before the skin on the back of my neck tried to crawl up over my head and hide in my mouth. I drew up short, and I must have made some kind of noise, because Billy shot a look back at me and asked, "Harry? What is it?"
I lifted a hand to silence him and peered at the darkness around me. "Keep your eyes open," I said. "I don't think we are alone."
From the shadows outside the light came a low hissing sound. The rest of my skin erupted in gooseflesh, and I shook my shield bracelet clear. I lifted my voice and said clearly, "I am the Wizard Dresden, Emissary of the Winter Court, bound to pay a call upon the Winter Lady. I've no time or desire for a fight. Stand clear and let me pass."
A voice - a voice that sounded like a tortured cat might, if some demented being gave it the gift of speech - mewled out of the shadows, grating on my ears. "We know who you are, wizard," the voice said. Its inflections were all wrong, and the tone seemed to come from not far above the ground, somewhere off to my right. Elidee let out a high-pitched shriek of terror and zipped back to me, diving into my hair. I felt the warmth of the light around the tiny faerie like a patch of sunlight on my scalp.
I traded a look with Billy and turned toward the source of the voice. "Who are you?"
"A servant of the Winter Lady," the voice replied from directly behind me. "Sent here to guide you safely through this realm and to her court."
I turned in the other direction and peered more closely toward the sound of the voice. The werelight from my amulet suddenly gleamed off a pair of animal eyes, twenty feet away and a few inches from the floor. I looked back at Billy. He'd already noted the eyes and turned to put his back to mine, watching the darkness behind us.
