“I knew you’d do that,” said Mick’s voice, and I jumped. I really had forgotten there were other people in the room.

“I’m sorry,” I said, and yanked my eyes from the books and back to the pair of couches. “Excuse me.”

China Black’s face was uninformative, but Mr. Lyle was smiling broadly. “That’s only part of the collection,” he said. “The rest is in the library. I’ll take you there when we’ve finished tea.”

Chango — the rest. “Do you have any” — I fished in my memory for the name — “Marquez?”

“All of his, I think,” said Mr. Lyle gravely. “One of my favorites. Now, sit down and have some tea.”

I saw a wicker chair with a cushion that matched the couches on one side of the fireplace. I carried it over and set it firmly down with its back to the bookcases. Which meant the seating was now U-shaped, with me halfway between the two couches.

Mr. Lyle hadn’t meant tea; he’d meant Tea. On the low table that separated the couches was a brass samovar, a plate of sandwiches, a bowl of dark muffins the size of dandelion puff-balls, a tray of cookies with specks of something in them, and a bowl of strawberries. There were also two cups. I looked to see who else hadn’t gotten tea yet, but Mick, Frances, China Black, and Mr. Lyle were all holding theirs. Maybe the dog had decided to wait.

The tea was mint, the sandwiches were cucumber and basil, the muffins were carrot, and the specks in the cookies were caraway. Then, I didn’t think that was significant. Tasty, but not significant. Now I wonder: How much of what I ate at that meal came from the garden that held that house like a cupped hand?

“You are safe here,” China Black said, “as long as you are our guests.” She was stern and distant, the patron of some church that put mercy after judgment. Her voice was roughened a little, as if from hard use. “It seemed to me we must have safety before we could speak freely. But now I would like to know why you are here.” And she looked at Frances and Mick.

Since her attention was elsewhere, I studied her over the edge of my cup. She wore a long, sleeveless olive-green dress, and a headwrap of green and yellow. Her nose, in profile, was high-bridged, and the nearest eyebrow shone like a streak of sweat. Her eyes were almond-shaped and sleepy-looking. I didn’t think she was sleepy.

“I’d like to know why you ask,” said Frances, smiling blandly.

Trust Frances to put all this amicability to flight. She watched us over her teacup like a panther eyeing a herd of antelope.

China Black was unruffled. “Would you like my credentials?”

“It’s a start,” Frances said.

Our hostess — was she our hostess? — seemed almost pleased. “This is a city divided in power. There is A. A. Albrecht, who sits at what he thinks is the heart, and tries to keep the flow of power all one way, all toward himself. He does not know, or care, perhaps, that the City is an organism, and that without its circulation, it will die. I am a houngan; I was chosen by the snake thirty years ago to serve the spirits, and the living. I and those like me try to keep the City’s lifeblood flowing in spite of Albrecht.”
