visualizes werewolf murder

Murphy's face was set in concern, for me, her blue eyes gentle. I saw her wipe the expression away, as quickly as a shadow crosses the floor, a smoothing of lines that left her features neutral. I guess she hadn't expected me to turn to her. "Take a look around a little more," she said. "Then we'll talk."
 "What am I looking for?" I asked her.
"You'll know it," she said. Then added, in a whisper that I think she didn't intend me to hear, "I hope."
I turned back to my work, and looked around the room. Off to one side, one of the windows was broken. Near it was a table, lying askew on the floor, its legs warped and bent. I walked over to it.
Broken glass littered the ground around the collapsed table. Since the glass was on the inside of the building, something must have come in through the window. There was blood on several of the broken pieces of glass. I picked up one of the larger ones and frowned at it. The blood was dark red, and not yet wholly dried. I took a white handkerchief from my pocket, folded the shard of glass into it, and then slipped it into the pocket of my duster.
I rose and paced over the floor, my eyes downcast, studying the dust. In one spot, it was rubbed almost clean off the floor, as though a struggle had taken place there without blood being spilled. In another spot, where the halogen lamps didn't quite reach, there was a pool of silver moonlight below a window. I knelt down beside it.
In the center of the pool was a paw print, in the dust, a paw print almost as big as my spread hand. Canine. Dots at the tips of the paw spoke of heavy nails, almost claws.
I looked up through the window at the rounded silver shape of the almost-full moon.
"Oh, hell," I breathed. "Oh, hell."
Murphy came toward me and watched me silently for a moment, waiting. I licked my lips, stood up, and turned to her. "You've got problems."
"No kidding. Talk to me, Dresden."
I nodded, then pointed at the window. "The attacker probably came in there. He went after the victim, attacked him, got the gun away from him, and killed him. It's the attacker's blood on the window. They struggled a while, over there by that clean spot, maybe, and Spike made a break for the door. He didn't make it there. He got torn to pieces first."
I turned toward Murphy, looking down at her solemnly. "You've had other murders happen in the same way. Probably about four weeks ago, when the moon was last full. Those were the other killings you were talking about."
Murphy glanced at my face for a moment, keeping her eyes off mine, and nodded her head. "Yeah. Four weeks ago, almost exactly. But no one else picked up the full moon angle. Just me."
"Uh-huh. Then you should see this, too," I said. I led her over to the window and showed her the paw print in the dust beneath it. She regarded it in silence.
"Harry," she said after a minute. "Are there such things as werewolves?" She brushed a strand of hair back from her cheek, a small and oddly vulnerable gesture. She folded her arms over her stomach, as though she were cold.
I nodded. "Yeah. Not like you see in the movies, but yeah. I figure that's what you got going here."
