the Empire State Building. "Manhattan has other problems. Other gods. It's best we stay separate."
"Other what?" Sadie demanded.
"Nothing." Amos walked past us to the steersman. He plucked off the man's hat and coat--and there was no one underneath. The steersman simply wasn't there. Amos put on his fedora, folded his coat over his arm, then waved toward a metal staircase that wound all the way up the side of the warehouse to the mansion on the roof.
"All ashore," he said. "And welcome to the Twenty-first Nome."
"Gnome?" I asked, as we followed him up the stairs. "Like those little runty guys?"
"Heavens, no," Amos said. "I hate gnomes. They smell horrible."
"But you said--"
"Nome, n-o-m-e. As in a district, a region. The term is from ancient times, when Egypt was divided into forty-two provinces. Today, the system is a little different. We've gone global. The world is divided into three hundred and sixty nomes. Egypt, of course, is the First. Greater New York is the Twenty-first."
Sadie glanced at me and twirled her finger around her temple.
"No, Sadie," Amos said without looking back. "I'm not crazy. There's much you need to learn."
We reached the top of the stairs. Looking up at the mansion, it was hard to understand what I was seeing. The house was at least fifty feet tall, built of enormous limestone blocks and steelframed windows. There were hieroglyphs engraved around the windows, and the walls were lit up so the place looked like a cross between a modern museum and an ancient temple. But the weirdest thing was that if I glanced away, the whole building seemed to disappear. I tried it several times just to be sure. If I looked for the mansion from the corner of my eye, it wasn't there. I had to force my eyes to refocus on it, and even that took a lot of willpower.
Amos stopped before the entrance, which was the size of a garage door--a dark heavy square of timber with no visible handle or lock. "Carter, after you."
"Um, how do I--"
"How do you think?"
Great, another mystery. I was about to suggest we ram Amos's head against it and see if that worked. Then I looked at the door again, and I had the strangest feeling. I stretched out my arm.
Slowly, without touching the door, I raised my hand and the door followed my movement-sliding upward until it disappeared into the ceiling.
Sadie looked stunned. "How..."
"I don't know," I admitted, a little embarrassed. "Motion sensor, maybe?"
"Interesting." Amos sounded a little troubled. "Not the way I would've done it, but very good.
Remarkably good."
"Thanks, I think."
Sadie tried to go inside first, but as soon as she stepped on the threshold, Muffin wailed and almost clawed her way out of Sadie's arms.
Sadie stumbled backward. "What was that about, cat?"
"Oh, of course," Amos said. "My apologies." He put his hand on the cat's head and said, very formally, "You may enter."
"The cat needs permission?" I asked.
"Special circumstances," Amos said, which wasn't much of an explanation, but he walked inside without saying another word. We followed, and this time Muffin stayed quiet.
"Oh my god..." Sadie's jaw dropped. She craned her neck to look at the ceiling, and I thought the gum might fall out of her mouth.
"Yes," Amos said. "This is the Great Room."
I could see why he called it that. The cedar-beamed ceiling was four stories high, held up by carved stone pillars engraved with hieroglyphs. A weird assortment of musical instruments and Ancient Egyptian weapons decorated the walls. Three levels of balconies ringed the room, with rows of doors all looking out on the main area. The fireplace was big enough to park a car in, with a plasma-screen TV above the mantel and massive leather sofas on either side. On the floor was a snakeskin rug, except it was forty feet long and fifteen feet wide--bigger than any snake.
Outside, through glass walls, I could see the terrace that wrapped around the house. It had a swimming pool, a dining
