Ten minutes later I stood up, went into the bathroom, put cold water on my face and eyes. I had not solved anything and had not wholly calmed down, but my nerves were no longer snapping like a flag in a high wind. I had been holding myself in ever since I had begun to suspect that something was seriously wrong, which was - when? When nothing seemed quite right at the fire pit? Later? Well, with utter certainty when I saw one 20,000-ton ship subst.i.tuted for another.

My father used to tell me, 'Alex, there is nothing wrong with being scared... as long as you don't let it affect you until the danger is over. Being hysterical is okay, too... afterwards and in private. Tears are not unmanly... in the bathroom with the door locked. The difference between a coward and a brave man is mostly a matter of timing.'

I'm not the man my father was but I try to follow his advice. If you can learn not to jump when the firecracker goes off - or whatever the surprise is - you stand a good chance of being able to hang tight until the emergency is over.

This emergency was not over but I had benefited by the catharsis of a good case of shakes. Now I could take stock.

Hypotheses:

a) Something preposterous has happened to the world around me, or

b) Something preposterous has happened to Alex Hergensheimer's mind; he should be locked up and sedated.

I could not think of a third hypothesis; those two seemed to cover all bases. The second hypothesis I need not waste time on. If, I were raising snakes in my hat, eventually other people would notice and come around with a straitjacket and put me in a nice padded room.

So let's a.s.sume that I am sane (or nearly so; being a little bit crazy is helpful). If I am okay, then the world is .out of joint. Let's take stock.

That wallet. Not mine. Most wallets are generally similar to each other and this one was much like mine. But carry a wallet for a few years and it fits you; it is distinctly yours. I had known at once that this one was not mine. But I did not want to say so to a ship's petty officer who insisted on, 'recognizing' me as 'Mr Graham'.

I took out Graham's wallet and opened it.

Several hundred francs - count it later.

Eighty-five dollars in paper - legal tender of 'The United States of North America'.

A driver's license issued to A. L. Graham.

There were more items but I came across a window occupied by a typed notice, one that stopped me cold:

Anyone finding this wallet may keep any money in it as a reward if he will be so kind as to return the wallet to A. L. Graham, cabin C109, S.S. KONGE KNUT, Danish American Line, or to any purser or agent of the line. Thank you. A.L.G.

So now I knew what had happened to the Konge Knut; she had undergone a sea change.

Or had I? Was there truly a changed world and therefore a changed ship? Or were there two worlds and had I somehow walked through fire into the second one? Were there indeed two men and had they swapped destinies? Or had Alex Hergensheimer metamorphized into Alec Graham while M. V. Konge Knut changed into S. S. Konge Knut? (While the North American Union melted into the United States of North America?)

Good questions. I'm glad you brought them up. Now, cla.s.s, are there any more questions

When I was in middle school there was a spate of magazines publishing fantastic, stories, not alone ghost stories but weird yarns of every sort. Magic ships plying the ether to, other stars. Strange inventions. Trips to the centre of the earth. Other 'dimensions'. Flying machines. Power from burning atoms. Monsters created in secret laboratories.

I used to buy them and hide them inside copies of Youth's Companion and of Young Crusaders knowing instinctively that my parents would disapprove and confiscate. I loved them and so did my outlaw chum Bert.

It couldn't last. First there was an editorial in Youth's Companion: 'Poison to the Soul - Stamp it Out!' Then our pastor, Brother Draper, preached a sermon against such mind-corrupting trash, with comparisons to the evil effects of cigarettes and booze. Then our state outlawed such publications under the 'standards of the community' doctrine even before pa.s.sage of the national law and the parallel executive order.

And a cache I had hidden 'perfectly' in our attic disappeared. Worse, the works of Mr H. G. Wells and M. Jules Verne and some others were taken out of our public library.

You have to admire the motives of our spiritual leaders and elected officials in seeking to protect the minds of the young. As Brother Draper pointed out, there are enough exciting and adventurous stories in the Good Book to satisfy the needs of every boy and girl in the world; there was simply no need for profane literature. He was not urging censorship of books for adults, just for the impressionable young. If persons of mature years wanted to read such fantastic trash, suffer them to do so - although he, for one, could not see why any grown man would want to.

I guess I was one of the 'impressionable young' - I still miss them.

I remember particularly one by Mr Wells: Men Like G.o.ds. These people were driving along in an automobile when an explosion happens and they find themselves in another world, much like their own but better. They meet the people who live there and there is explanation about parallel universes and the fourth dimension and such.

That was the first installment. The Protect-Our-Youth state law was pa.s.sed right after that, so I never saw the later installments.

One of my English professors who was bluntly opposed to censorship once said that Mr Wells had invented every one of the basic fantastic themes, and he cited this story as the origin of the multiple-universes concept. I was intending to ask this prof if he knew where I could find a copy, but I put it off to the end of the term when I would be legally 'of mature years' - and waited too long; the academic senate committee on faith and morals voted against tenure for that professor, and he left abruptly without finishing the term.

Did something happen to me like that which Mr Wells described in Men Like G.o.ds? Did Mr Wells have the holy gift of prophecy? For example, would men someday actually fly to the moon? Preposterous!

But was it more preposterous than what had happened to me?

As may be, here. I was in Konge Knut (even though she was not my, Konge Knut) and the sailing board at the gangway showed her getting underway at 6 p.m. It was already late afternoon and high time for me to decide.

What to do? I seemed to have mislaid my own ship, the Motor Vessel Konge Knut. But the crew (some of the crew) of the Steamship Konge Knut seemed ready to accept me as 'Mr Graham', pa.s.senger.

Stay aboard and try to brazen it out? What if Graham comes aboard (any minute now!) and demands to know what I am doing in his room?

Or go ash.o.r.e (as I should) and go to the authorities with my problem?

Alex, the French colonial authorities will love you. No baggage, only the clothes on your back, no money, not a sou - no pa.s.sport! Oh, they will love you so much they'll give you room and board for the rest of your life ... in an oubliette with a grill over the top.

There's money in that wallet.

So? Ever heard of the Eighth Commandment? That's his money.

But it stands to reason that he walked through the fire at the same time you did but on this side, this world or whatever - or his wallet would not have been waiting for you. Now he has your wallet. That's logical.

Listen, my r.e.t.a.r.ded friend, do you think logic has anything to do with the predicament we are in?

Well

Speak up!

No, not really. Then how about this? Sit tight in this room. If Graham shows up before, the ship sails, you get kicked off the ship, that's sure. But you would be no worse off than you will be if you leave now. If he does not show up, then you take his place at least as far as Papeete. That's a big city; your chances of coping with the situation are far better there. Consuls and such.

You talked me into it.

Pa.s.senger ships usually publish a daily newspaper for the pa.s.sengers - just a single or double sheet filled with thrilling items such as 'There will be a boat drill at ten o'clock this morning. All pa.s.sengers are requested -' and 'Yesterday's mileage pool was won by Mrs Ephraim Glutz of Bethany, Iowa' and, usually, a few news items picked up by the wireless operator. I looked around for the ship's paper and for the 'Welcome Aboard!' This latter is a booklet (perhaps with another name) intended to make the pa.s.senger newly aboard sophisticated in the little world of the ship: names of the officers, times of meals, location of barber shop, laundry, dining room, gift shop (notions, magazines, toothpaste), and how to place a morning call, plan of the ship by decks, location of life preserver, how, to find your lifeboat station, where to get your table a.s.signment-

'Table a.s.signment'! Ouch! A pa.s.senger who has been aboard even one day does not have to ask how to find his table in the dining room. It's the little things that trip you. Well, I'd have to bull it through.

The welcome-aboard booklet was tucked into Graham's desk. I thumbed through it, with a mental note to memorize all key facts before I left this room - if I was still aboard when the ship sailed - then put it aside, as I had found the ship's newspaper:

The King's Skald it was headed and Graham, bless him, had saved all of them from the day he had boarded the ship... at Portland, Oregon, as I deduced from the place and date line of the, earliest issue. That suggested that Graham was ticketed for the entire cruise, which could be important to me. I had expected to go back as I had arrived, by airship - but, even if the dirigible liner Admiral Moffett existed in this world or dimension or whatever, I no longer had a ticket for it and no money with which to buy one. What do these French colonials do to a tourist who has no money? Burn him at the stake? Or merely draw and quarter him? I did not want to find out. Graham's roundtrip ticket (if he had one) might keep me from having to find out.

(If he didn't show up in the next hour and have me kicked off the ship.)

I did not consider remaining in Polynesia. Being a penniless beachcomber on Bora-Bora or Moorea may have been practical a hundred years ago but today the only thing free in these islands is contagious disease.

It seemed likely that I would be just as broke and just as much a stranger in America but nevertheless I felt that I would be better off in my native land. Well, Graham's native land.
