"What's the matter?" I asked. "It isn't there!"

"No Wigwam?"

"No Wigwam," she said. Then I guess the tone of my voice gave her a belated hint, because she looked up, her gray eyes wide and accusing. "You knew!"

"I knew we wouldn't find it in the phone book" I said.

"How-"

"It was checked two nights ago along with your personal history and various other things."

She frowned as if completely bewildered. "You knew, and still you had us come all this way? You let me-" She stopped, and said naively, "You might at least have told me!"

I said, "It was your wild-goose chase, glamor girl. I just came along to watch the show." She gasped, and I said, "Sure, I let you put on your act. It was very good. Congratulations. The double-take, the surprised expression… Anybody'd have thought you really expected to find a place called the Wigwam!" I grimaced. "Now, why don't you just break down, Gail, and tell me what your sister really said, and why you went to the trouble of making up this crazy story about an Indian lodge…"

"Excuse me, sir."

The voice came from behind me. Well, I should have known better than to pick a public driveway for the scene, but I was just about through, anyway. I'd done my part to establish the unbearable Mr. Helm for another day. He'd slipped a little last night; he'd been almost human early this morning, but now he was right back in form. I turned.

"That'll be three-eighty for the gas and fifty cents for taking off the chains, plus tax," the filling station man said. His stolid, freckled face said that quarrels between his customers were none of his business, much as he'd like to know what the hell it was all about. "Oil and water okay. I put your chains in back."

I gave him my credit card. The sound of running footsteps told me Gail was gone; I heard the truck door open and close, hard. I followed the man into the station to sign the ticket.

"There wouldn't be a place called The Wigwam in town?" I asked casually. "A motel or a restaurant or something?"

"There's nothing called the Wigwam, Mister, but the Turquoise Motel's a nice place to stay, and if you want something to eat or drink, there's the Chloe Bar and Grill…

When I got behind the wheel, she was sitting at the other end of the seat, looking straight ahead. I started up the truck and drove away. At the end of town I stopped at the junction where our north-south highway intersected the big paved road going east over the mountains to Roswell in the Pecos Valley, and west over the mountains to Socorro, on the Rio Grande. I turned left and drove out of town. A little way down the road a sign- similar to ones we'd seen while crossing the missile range farther south-warned that the road was occasionally closed for one-and-one-half hour periods during tests. Ahead, the road dipped down into a wide, desolate, snow-covered basin.

"The mountains straight across," I said, "are called the Oscuras, I think. The Army's got a lot of stuff back in there, or did the last time I was through. It's all restricted as hell back in there. Those mountains, just visible, to the south are the Manzanitas."

That got a small reaction from her; she deigned to turn her head and look, but she didn't speak.

"Yes," I said, "that's where the underground test will take place shortly, if it goes off on schedule. It's already been postponed once, and this weather is going to make things rough out there." I paused. "We don't think much of your Wigwam story, Gail, but we're inclined to buy Carrizozo. You can see how it might be the logical place for a drop-that's the jargon for an underground station or post office. It's right where the main highways cross. Anybody going into or coming out of the test area wouldn't need much of an excuse to stop off in Carrizozo to pick up instructions or deliver the goods."

She didn't answer, of course. Her profile was very handsome, but as cold and lifeless as the face on a coin. I drove back and zigzagged through the town, saying nothing. It took three quarters of an hour, but she finally broke down and spoke.

"May I ask what we are doing?"

I said, "Giving you the benefit of the doubt, glamor girl. I don't think much of that Wigwam story, but I'm willing to be convinced. Now that you've finally come out of your trance, suppose you watch that side of the street while I watch this one. Any sign you can't read, just holler and I'll stop."

She turned at last to look at me directly. "But-"

"So maybe it isn't in the phone book," I said. "And maybe it isn't a motel or restaurant, maybe it's a little curio shop or candy store without a phone. Maybe it's a private residence with a cute sign out front, only listed under tbe owner's name."

"But you said-" She paused. "You implied… dreadful things!"

"Gail," I said, "in this business, there's a maxim that goes: suspect everybody once except a woman you've slept with; suspect her twice. You will admit it's odd that there's no such place in the directory, won't you?"

"But you don't really believe-"

"At this stage of the proceedings, I don't believe anything," I said. "I don't disbelieve anything, either. What do you want me to do, take you on faith?"

She flushed slightly, "No, but-"

"Hold it," I said. "We can argue about it later. Look over there."

"What is it?" Her voice was suddenly eager. "Is it-"

"Not what we're looking for, but there are an awful lot of government cars congregating at that motel up ahead. They weren't there the last time we came by… I'll be damned!" I said. "There's Rennenkamp, Old Man Atom himself, the director of the test. I've seen his picture in the paper. Looks like something has got him in a real calm and objective mood as befits a scientist of his age and reputation…"

I shouldn't have slowed down, of course. Making a U-turn to avoid passing the place again would have looked too obvious, but I should have driven past rapidly, looking straight ahead, instead of gawking like a tourist at the tall, white-haired old man who was violently haranguing a shorter, darker man in front of a gray car with u.s. GovERNMENT-INTEBAOENCY MOTOR POOL stenciled on the side.

I guess I was curious as to whether the old gent wanted to get started, snow or no snow, and they wouldn't let him, or whether he was telling them he was damned if he was going to risk getting stuck out in the valley today, and to hell with scientific progress and national prestige.

It certainly wouldn't hurt to get some idea as to whether or not the test might be delayed again-but as I came abreast of the place with my bare face showing at the open cab window, a man came out of the motel office and stopped to stare.

"Matt!" he shouted, starting across the sidewalk. "Matt Helm! What the hell are you doing here, you old bastard?"

It was the last question in the world I wanted to be asked in that particular place at that particular time.
