“Oh, yes. I followed you last night and over-heard Vicky telling Konstanze’s life story. It wasn’t hard to figure out what it meant, so far as the hiding place of the shrine was concerned. I had prepared the tunnel with no specific plan in mind—an emergency reserve, you might say—but I had to get you down there right away, before you could use your information. I had plenty of time after that to search.”

“I hope you haven’t told anyone else where it is,” Tony said.

I wished George would stop grinning. He looked like an Aztec death mask—the kind that is half teeth.

“I’m not such a fool as that.”

Tony wasn’t as calm as he seemed. I could see the tension of bunched-up muscles in his legs and shoulders. I kept very still and watched him. He was leading up to something and I wanted to be ready to back him up, whatever he did.

“I don’t know, Nolan,” he said. “I find your position somewhat shaky. What are you going to do with Irma?”

“Somnambulists are accident-prone, old son. They even have fatal accidents.”

“And you can always go down after you throw her off and make sure.”

“What’s one more?” said George.

It took me a couple of seconds to understand what he meant.

“Now, wait,” I said energetically. “Let’s not be hasty. You haven’t killed anybody yet. We can’t even accuse you of attempted murder; shutting us up in that hole was just a boyish prank, right? Why kill anybody? Just take the shrine and split. We haven’t any proof.”

“Wouldn’t work,” said George promptly. He waved the gun at Tony, who tried not to cringe. “He’s been too nosy. Sending cables all over the place.”

“You’ve been reading my mail!” Tony said angrily.

“Only the cables that arrived today. You know too much about the state of my finances, brother. And you were too inquisitive about Herr Schmidt.”

“You crook,” I said to Tony. “Were those the cables you sent that day it rained? How did you know where to inquire about Schmidt? Why didn’t you tell me?”

“You have a lot of nerve talking about cheating,” Tony shouted. “Squatting like a setting hen on all those little tidbits you dug up—”

“Sssh!” George danced irritably up and down. “Somebody will hear you!”

I expected Tony to jump him then; I braced myself, ready to move. There was a nasty cold lump at the pit of my stomach. I had never seen a gun from quite that angle. It is a disconcerting sight, and I had no desire to see it any closer. But we had to do something; I didn’t intend to let myself be herded back into that hellish tunnel without putting up a fight. We would be in a better position to attack if we waited till George had us on the stairs. But we couldn’t wait. He was going to kill Irma first.

Tony settled back.
