Maybe thirty yards short of the shop, I crossed some kind of invisible line where the oppressive, dangerous atmosphere of the bad part of town lessened by several degrees. A few steps later I caught my first glance of a U of C campus building, far down the block. I felt myself relax a little in response, but that unspoken promise of safety and the rule of law was only an illusion. The closer you got to campus, the less crime occurred, but there was nothing other than convention and slightly more frequent police patrols to keep the darker elements of the city from pushing the boundaries.

Well, there was one more thing. But I couldn't afford to get involved with it. Mavra's prohibition against involving anyone else meant that even if I wanted extra help, I didn't dare ask for it. I was on my own. And if trouble came looking, I'd have to handle it alone.

Predators respond to body language. I walked like I was on my way to rip someone's face off, until I made it to the shop and entered the store.

Artemis Bock, proprietor, sat behind a counter facing the door. He was a bear of a man in his late fifties, broad-shouldered, unshaven, and heavyset with weathered muscle under a layer of comfortable living. He had knuckles the size and texture of golf balls, marked with old scars from whatever career he'd pursued before he'd become a storekeeper. He wasn't anything so strong as a wizard, but he knew his way around Chicago, around basic magical theory, and his shop was protected with half a dozen subtle wards that did a lot to encourage people looking for trouble to look elsewhere.

The door chimes tinkled as I came in, and there was a deeper chime from somewhere behind the counter. Bock had one arm on the counter and one out of sight under it until he peered over his reading glasses at my face, and nodded. He folded his arms onto the counter again, hunched over what looked like an auto magazine, and said, "Mister Dresden."

"Bock," I replied with a nod.

His eyes flickered over my staff, and I got the impression that he noticed or sensed the gun under the jacket.

"I need to get into the cage," I told him.

His shaggy eyebrows drew together. "The Wardens were here not a month ago. I run a clean shop. You know that."

I lifted my gloved hand in a pacifying gesture. "This isn't an inspection tour. Personal business."
