"Why, I suppose so. The Crystal Cafe. It's just about a block--"

"I know where it is. Meet you in half an hour!" And the receiver clicked.

The Crystal Cafe was no longer painted red, but the temperature was still up. And they had added piped-in music interspersed with commercials. The advertis.e.m.e.nts were for Frosty-Flip, Marlin Cigarettes--"They're sanitized," the announcer purred--and something called Choco-Bite candy bars that Burckhardt couldn't remember ever having heard of before. But he heard more about them quickly enough.

While he was waiting for Swanson to show up, a girl in the cellophane skirt of a nightclub cigarette vendor came through the restaurant with a tray of tiny scarlet-wrapped candies.

"Choco-Bites are _tangy_," she was murmuring as she came close to his table. "Choco-Bites are _tangier_ than tangy!"

Burckhardt, intent on watching for the strange little man who had phoned him, paid little attention. But as she scattered a handful of the confections over the table next to his, smiling at the occupants, he caught a glimpse of her and turned to stare.

"Why, Miss Horn!" he said.

The girl dropped her tray of candies.

Burckhardt rose, concerned over the girl. "Is something wrong?"

But she fled.

The manager of the restaurant was staring suspiciously at Burckhardt, who sank back in his seat and tried to look inconspicuous. He hadn't insulted the girl! Maybe she was just a very strictly reared young lady, he thought--in spite of the long bare legs under the cellophane skirt--and when he addressed her, she thought he was a masher.

Ridiculous idea. Burckhardt scowled uneasily and picked up his menu.

"Burckhardt!" It was a shrill whisper.

Burckhardt looked up over the top of his menu, startled. In the seat across from him, the little man named Swanson was sitting, tensely poised.

"Burckhardt!" the little man whispered again. "Let's get out of here!

They're on to you now. If you want to stay alive, come on!"

There was no arguing with the man. Burckhardt gave the hovering manager a sick, apologetic smile and followed Swanson out. The little man seemed to know where he was going. In the street, he clutched Burckhardt by the elbow and hurried him off down the block.

"Did you see her?" he demanded. "That Horn woman, in the phone booth?

She'll have them here in five minutes, believe me, so hurry it up!"

Although the street was full of people and cars, n.o.body was paying any attention to Burckhardt and Swanson. The air had a nip in it--more like October than June, Burckhardt thought, in spite of the weather bureau. And he felt like a fool, following this mad little man down the street, running away from some "them" toward--toward what? The little man might be crazy, but he was afraid. And the fear was infectious.

"In here!" panted the little man.

It was another restaurant--more of a bar, really, and a sort of second-rate place that Burckhardt had never patronized.

"Right straight through," Swanson whispered; and Burckhardt, like a biddable boy, side-stepped through the ma.s.s of tables to the far end of the restaurant.

It was "L"-shaped, with a front on two streets at right angles to each other. They came out on the side street, Swanson staring coldly back at the question-looking cashier, and crossed to the opposite sidewalk.

They were under the marquee of a movie theater. Swanson's expression began to relax.

"Lost them!" he crowed softly. "We're almost there."

He stepped up to the window and bought two tickets. Burckhardt trailed him in to the theater. It was a weekday matinee and the place was almost empty. From the screen came sounds of gunfire and horse's hoofs. A solitary usher, leaning against a bright bra.s.s rail, looked briefly at them and went back to staring boredly at the picture as Swanson led Burckhardt down a flight of carpeted marble steps.

They were in the lounge and it was empty. There was a door for men and one for ladies; and there was a third door, marked "MANAGER" in gold letters. Swanson listened at the door, and gently opened it and peered inside.

"Okay," he said, gesturing.

Burckhardt followed him through an empty office, to another door--a closet, probably, because it was unmarked.

But it was no closet. Swanson opened it warily, looked inside, then motioned Burckhardt to follow.

It was a tunnel, metal-walled, brightly lit. Empty, it stretched vacantly away in both directions from them.

Burckhardt looked wondering around. One thing he knew and knew full well:

No such tunnel belonged under Tylerton.

There was a room off the tunnel with chairs and a desk and what looked like television screens. Swanson slumped in a chair, panting.

"We're all right for a while here," he wheezed. "They don't come here much any more. If they do, we'll hear them and we can hide."

"Who?" demanded Burckhardt.

The little man said, "Martians!" His voice cracked on the word and the life seemed to go out of him. In morose tones, he went on: "Well, I think they're Martians. Although you could be right, you know; I've had plenty of time to think it over these last few weeks, after they got you, and it's possible they're Russians after all. Still--"

"Start from the beginning. Who got me when?"

Swanson sighed. "So we have to go through the whole thing again. All right. It was about two months ago that you banged on my door, late at night. You were all beat up--scared silly. You begged me to help you--"

"_I_ did?"

"Naturally you don't remember any of this. Listen and you'll understand. You were talking a blue streak about being captured and threatened, and your wife being dead and coming back to life, and all kinds of mixed-up nonsense. I thought you were crazy. But--well, I've always had a lot of respect for you. And you begged me to hide you and I have this darkroom, you know. It locks from the inside only. I put the lock on myself. So we went in there--just to humor you--and along about midnight, which was only fifteen or twenty minutes after, we pa.s.sed out."

"Pa.s.sed out?"

Swanson nodded. "Both of us. It was like being hit with a sandbag.

Look, didn't that happen to you again last night?"

"I guess it did," Burckhardt shook his head uncertainly.

"Sure. And then all of a sudden we were awake again, and you said you were going to show me something funny, and we went out and bought a paper. And the date on it was June 15th."

"June 15th? But that's today! I mean--"
