He set the book down next to the cash register, reached into a pocket, found two quarters, and placed them on the counter alongside the book.

“Ah, poor Cowper,” I said, picking up the book. Its binding was shaky, which was why it had found its way to my bargain table. “My favorite’s ‘The Retired Cat.’ I’m pretty sure it’s in this edition.” He shifted his weight from foot to foot while I scanned the table of contents. “Here it is. Page one-fifty. You know the poem?”

“I don’t think so.”

“You’ll love it. The bargain books are forty cents or three for a dollar, which is even more of a bargain. You just want the one?”

“That’s right.” He pushed the two quarters an inch or so closer to me. “Just the one.”

“Fine,” I said. I looked at his face. All I could really see was his brow, and it looked untroubled, and I would have to do something about that. “Forty cents for the Cowper, and three cents for the Governor in Albany, mustn’t forget him, and what does that come to?” I leaned over the counter and dazzled him with my pearly-whites. “I make it thirty-two dollars and seventy cents,” I said.

“Huh?”

“That copy of Byron. Full morocco, marbled endpapers, and I believe it’s marked fifteen dollars. The Wallace Stevens is a first edition and it’s a bargain at twelve. The novel you took was only three dollars or so, and I suppose you just wanted to read it because you couldn’t get anything much reselling it.”

“I don’t know what you’re talking about.”

I moved out from behind the counter, positioning myself between him and the door. He didn’t look as though he intended to sprint but he was wearing running shoes and you never can tell. Thieves are an unpredictable lot.

“In the flight bag,” I said. “I assume you’ll want to pay for what you took.”

“This?” He looked down at the flight bag as if astonished to find it dangling from his fingers. “This is just my gym stuff. You know-sweat socks, a towel, like that.”
