I had run because it was my first startled reaction and probably because I knew I was there on what might be considered illegal business; if I succeeded, some poor inventor would be done out of his royalties.

I wished I hadn't run. Besides making me feel like a scared fool, I was sweaty and out of breath. Playing old men doesn't make climbing down fire escapes much tougher than it should be, but it doesn't exactly make a sprinter out of you--not by several lungfuls.

I sat there, breathing hard and trying to guess what next. I had no more idea of where to go for what I wanted than an ancient Egyptian set down in the middle of Times Square with instructions to sneak a mummy out of the Metropolitan Museum. I didn't even have that much information. I didn't know any part of the city, how it was laid out, or where to get the data that May Roberts had sent me for.

I opened the door quietly and looked both ways before going out. After losing myself in the cross-connecting corridors a few times, I finally came to an outside door. I stopped, tense, trying to get my courage.

My inclination was to slip, sneak or dart out, but I made myself walk away like a decent, innocent citizen. That was one disguise they'd never be able to crack. All I had to do was act as if I belonged to that time and place and who would know the difference?

There were other people walking as if they were in no hurry to get anywhere. I slowed down to their speed, but I wished wistfully that there was a crowd to dive into and get lost.

A man dropped into step and said politely, "I beg your pardon. Are you a stranger in town?"

I almost halted in alarm, but that might have been a giveaway. "What makes you think so?" I asked, forcing myself to keep at the same easy pace.

"I--didn't recognize your face and I thought--"

"It's a big city," I said coldly. "You can't know everyone."

"If there's anything I can do to help--"

I told him there wasn't and left him standing there. It was plain common sense, I had decided quickly while he was talking to me, not to take any risks by admitting anything. I might have been dumped into a police state or the country could have been at war without my knowing it, or maybe they were suspicious of strangers. For one reason or another, ranging from vagrancy to espionage, I could be pulled in, tortured, executed, G.o.d knows what. The place looked peaceful enough, but that didn't prove a thing.

I went on walking, looking for something I couldn't be sure existed, in a city I was completely unfamiliar with, in a time when I had no right to be alive. It wasn't just a matter of getting the information she wanted. I'd have been satisfied to hang around until she pulled me back without the data....

But then what would happen? Maybe the starvation cases were people who had failed her! For that matter, she could shoot me and send the remains anywhere in time to get rid of the evidence.

d.a.m.n it, I didn't know if she was better or worse than I'd supposed, but I wasn't going to take any chances. I had to bring her what she wanted.

There was a sign up ahead. It read: TO SHOPPING CENTER. The arrow pointed along the road. When I came to a fork and wondered which way to go, there was another sign, then another pointing to still more farther on.

I followed them to the middle of the city, a big square with a park in the center and shops of all kinds r.i.m.m.i.n.g it. The only shop I was interested in said: ELECTRICAL APPLIANCES.

I went in.

A neat young salesman came up and politely asked me if he could do anything for me. I sounded stupid even to myself, but I said, "No, thanks, I'd just like to do a little browsing," and gave a silly nervous laugh. Me, an actor, behaving like a frightened yokel! I felt ashamed of myself.

He tried not to look surprised, but he didn't really succeed. Somebody else came in, though, for which I was grateful, and he left me alone to look around.

I don't know if I can get my feelings across to you. It's a situation that n.o.body would ever expect to find himself in, so it isn't easy to tell what it's like. But I've got to try.

Let's stick with the ancient Egyptian I mentioned a while back, the one ordered to sneak a mummy out of the Metropolitan Museum. Maybe that'll make it clearer.

The poor guy has no money he can use, naturally, and no idea of what New York's transportation system is like, where the museum is, how to get there, what visitors to a museum do and say, the regulations he might unwittingly break, how much an ordinary citizen is supposed to know about which customs and such. Now add the possible danger that he might be slapped into jail or an insane asylum if he makes a mistake and you've got a rough notion of the spot I felt I was in. Being able to speak English doesn't make much difference; not knowing what's regarded as right and wrong, and the unknown consequences, are enough to panic anybody.

That doesn't make it clear enough.

Well, look, take the electrical appliances in that store; that might give you an idea of the situation and the way it affected me.

The appliances must have been as familiar to the people of that time as toasters and TV sets and lamps are to us. But the things didn't make a bit of sense to me ... any more than our appliances would to the ancient Egyptian. Can you imagine him trying to figure out what those items are for and how they work?

Here are some gadgets you can puzzle over:

There was a light fixture that you put against any part of a wall--no screws, no cement, no wires, even--and it held there and lit up, and it stayed lit no matter where you moved it on the wall. Talk about pin-up lamps ... this was really it!

Then I came across something that looked like an ashtray with a blue electric shimmer obscuring the bottom of the bowl. I lit my pipe--others I'd pa.s.sed had been smoking, so I knew it was safe to do the same--and flicked in the match. It disappeared. I don't mean it was swirled into some hidden compartment. _It vanished._ I emptied the pipe into the ashtray and that went, too. Looking around to make sure n.o.body was watching, I dredged some coins out of my pocket and let them drop into the tray. They were gone. Not a particle of them was left. A disintegrator? I haven't got the slightest idea.

There were little mirror boxes with three tiny dials on the front of each. I turned the dials on one--it was like using three dial telephones at the same time--and a pretty girl's face popped onto the mirror surface and looked expectantly at me.

"Yes?" she said, and waited for me to answer.

"I--uh--wrong number, I guess," I answered, putting the box down in a hurry and going to the other side of the shop because I didn't have even a dim notion how to turn it off.

The thing I was looking for was on a counter--a tinted metal box no bigger than a suitcase, with a lipped hole on top and small undisguised verniers in front. I didn't know I'd found it, actually, until I twisted a vernier and every light in the store suddenly glared and the salesman came rushing over and politely moved me aside to shut it off.

"We don't want to burn out every appliance in the place, do we?" he asked quietly.

"I just wanted to see if it worked all right," I said, still shaking slightly. It could have blown up or electrocuted me, for all I knew.

"But they always work," he said.

"Ah--always?"

"Of course. The principle is simple and there are no parts to get worn out, so they last indefinitely." He suddenly smiled as if he'd just caught the gist. "Oh, you were joking! Naturally--everybody learns about the Dynapack in primary education. You were interested in acquiring one?"

"No, no. The--the old one is good enough. I was just--well, you know, interested in knowing if the new models are much different or better than the old ones."

"But there haven't been any new models since 2073," he said. "Can you think of any reason why there should be?"

"I--guess not," I stammered. "But you never can tell."

"You can with Dynapacks," he said, and he would have gone on if I hadn't lost my nerve and mumbled my way out of the store as fast as I could.

You want to know why? He'd asked me if I wanted to "acquire" a Dynapack, not _buy_ one. I didn't know what "acquire" meant in that society. It could be anything from saving up coupons to winning whatever you wanted at some kind of lottery, or maybe working up the right number of labor units on the job--in which case he'd want to know where I was employed and the equivalent of social security and similar information, which I naturally didn't have--or it could just be fancy sales talk for buying.

I couldn't guess, and I didn't care to expose myself any more than I had already. And my blunder about the Dynapack working and the new models was nothing to make me feel at all easier.

Lord, the uncertainties and hazards of being in a world you don't know anything about! Daydreaming about visiting another age may be pleasant, but the reality is something else again.

"Wait a minute, friend!" I heard the salesman call out behind me.
