"Oh, I've read that one." She scrunched up her nose, eyes distant for a second, then said, "Two copies, right-hand shelf, third row from the top, eighth and ninth books from the left."

I blinked at her, then went to the shelf and found the book where she'd said. "Wow. Good call."

"Eidetic memory," she said with a pleased smile. "It's… sort of my talent." She gestured vaguely with the hand she'd touched me with.

"Must come in handy during inventory." I checked the shelf. "There's only one copy, though."

She frowned, then shrugged. "Mister Bock must have sold one this week."

"I bet he did," I said, troubled. It bothered me to think about Grevane standing in a store, speaking to people like Bock or Shiela. I pulled the cage closed and started slowly for the front of the store.

I opened the book. I'd heard it referenced before, in other works. It was supposed to deal with the lore around the Erlkoenig, or Elfking. He was supposed to be a faerie figure of considerable power, maybe a counterpart to the Queens of the Faerie Courts. The book had been compiled by Wizard Peabody early last century from the collected notes of a dozen different crusty wizards, most of them dead at the time, and was considered to be a work of nearly pure speculation.

"How much?" I asked.

"Should be on an index card inside the cover," Shiela said, walking politely beside me.

I looked. The book was worth half a month's rent. No wonder I'd never bought a copy. Business hadn't been bad lately, but between handling all of Mouse's licensing and shots and the trucks of food he ate, and Thomas's job troubles, I didn't have anything to spare. Maybe Bock would let me lease it or something.

Shiela and I walked out of the back room and started toward the front of the store. As we came out of the book areas, she said, "Well, I think you know the way from here. It was a pleasure meeting you, Harry."

"You too," I said, smiling. Hey, she was a woman, and pretty enough. Her smile was simply adorable. "Maybe I'll bump into you again sometime."

"I'd like that. Only next time without the gun."

"One of those old-fashioned girls, huh?" I said.

She laughed and walked back toward the rear of the store.

"Find what you needed?" Bock asked. There was an edge to his voice, something I couldn't quite place. He was definitely uncomfortable.

"I hope so," I said. "Uh. About the price…"

Bock looked at me hard from under his thick eyebrows.

"Uh. Would you take a check?"

He looked around the store and then nodded. "Sure, from you."

"Thanks," I said. I wrote out a check, hoping it wouldn't bounce before I got to the door, and sneaked my own glance around the shop. "Did I run out your customers?"

"Maybe," he said uncomfortably.

"Sorry," I said.

"It happens."
