'If you don't know, sir, I don't see how I can explain it.

Won't you try? Please!' (Could it be one of those cyclic emotional disturbances women are heir to?)

'Uh... Mr Graham, I knew it could not last beyond the end of the voyage - and believe me, I did not count on any more. I suppose it means more to me than it did to you. But I never thought that you would simply end it, with no explanation, sooner than we must.'

'Margrethe... I do not understand.'

'But you do know!'

'But I don't know.'

'You must know. It's been eleven days. Each night I've asked you and each night you've turned me down. Mr Graham, aren't you ever again going to ask me to come back later?'

'Oh. So that's what you meant! Margrethe -'

'Yes, sir?'

'I'm not "Mr Graham".' 'Sir?' 'My name is "Hergensheimer". It has been exactly eleven days since I saw you for the first time in my life. I'm sorry. I'm terribly sorry. But that is the truth.'

Now therefore be content, look upon me;

for it is evident unto you if I lie.

Job 6:28

MARGRETHE is both a warm comfort and a civilized adult. Never once did she gasp, or expostulate, or say, 'Oh, no or 'I can't believe it!' At my first statement she held very still, waited, then said quietly, 'I do not understand.'

'I don't understand it either,' I told her. 'Something happened when I walked through that fire pit. The world changed. This ship - 'I pounded the bulkhead beside us. '- is not the ship I was in before. And people call me "Graham"... when I know that my name is Alexander Hergensheimer. But it's not just me and this ship; it's the whole world. Different history. Different countries. No airships here.'

'Alec, what is an airship?'

'Uh, up in the air, like a balloon. It is a balloon, in a way. But it goes very fast, over a hundred knots.'

She considered it soberly. 'I think that I would find that frightening.'

I 'Not at all; it's the best way to travel. I flew down here in one, the Count von Zeppelin of North American Airlines. But this world doesn't have airships. That was the point that finally convinced me that this really is a different world - and not just some complicated hoax that someone had played on me. Air travel is so major a part of the economy of the world I knew that it changes everything else not to have it. Take - Look, do you believe me?

She answered slowly and carefully, 'I believe that you are telling the truth as you see it. But the truth I see is very different.'

'I know and that's what makes it so hard. I - See here, if you don't hurry, you're going to miss dinner, right?'

'It does not matter.'

'Yes, it does; you must not miss meals just because I made a stupid mistake and hurt your feelings. And if I don't show up, Inga will send somebody up to find out whether I'm ill or asleep or whatever; I've seen her do it with others at my table. Margrethe - my very dear! - I've wanted to tell you. I've waited to tell you. I've needed to tell you. And now I can and I must. But I can't do it in five minutes standing up. After you turn down beds tonight can you take time to listen to me?'

'Alec, I will always take all the time for you that you need.'

'All right. You go down and eat, and I'll go down and touch base at least - get Inga off my neck - and I'll meet you here after you turn down beds. All right?'

She looked thoughtful. 'All right. Alec - Will you kiss me again.'

That's how I knew she believed me. Or wanted to believe me. I quit worrying. I even ate a good dinner, although I hurried.

She was waiting for me when I returned, and stood up as I came in. I took her in my arms, pecked her on the nose, picked her up by her elbows and sat her on my bunk; then I sat down in the only chair. 'Dear one, do you think I'm crazy.

'Alec, I don't know what to tink.' (Yes, she said 'tink'. Once in a long while, under stress of emotion, Margrethe would lose the use of the theta sound. Otherwise her English accent was far better than my tall-corn accent, harsh as a rusty saw.)

'I know,' I agreed. 'I had the same problem. Only two ways to look at it. Either something incredible did happen when I walked through the fire, something that changed my whole world. Or I'm as crazy I as a pet 'coon. I've spent days checking the facts... and the world has changed. Not just airships. Kaiser Wilhelm the Fourth is missing and some silly president named "Schmidt is in his place. Things like that.'

'I would not call Herr Schmidt "silly". He is quite a good president as German presidents go.'

'That's my point, dear. To me, any German president looks silly, as Germany is - in my world - one of the last western monarchies effectively unlimited. Even the Tsar is not as powerful.'

'And that has to be my point, too, Alec. There is no Kaiser and there is no Tsar. The Grand Duke of Muscovy is a constitutional monarch and no longer claims to be suzerain over other Slavic states.'

'Margrethe, we're both saying the same thing. The world I grew up in is gone. I'm having to learn about a different world. Not a totally different world. Geography does not seem to have changed, and not all of history. The two worlds seem to be the same almost up to the beginning of the twentieth century. Call it eighteen-ninety. About a hundred years back something strange happened and the two worlds split apart... and about twelve days ago something equally strange happened to me and I got bounced into this world.' I smiled at her. 'But I'm not sorry. Do you know why? Because you are in this world.'.

'Thank you. It is important to me that you are in it, too.'

'Then you do believe me. Just as I have been forced to believe it. So much so that I've quit worrying about it. Just one thing really bothers me - What became of Alec Graham? Is he filling my place in my world? Or what?'

She did not answer at once, and when she did, the answer did not seem responsive. 'Alec, will you please take down your trousers?'

'What did you say, Margrethe?'

'Please. I am not making a joke and I am not trying to entice you. I must see something. Please lower your trousers.'

I don't see - All right.' I shut up and did as she asked not easy in evening dress. I had to take off my mess jacket, then my cummerbund, before I was peeled enough to let me slide the braces off my shoulders.

Then, reluctantly, I started unbuttoning my fly. (Another shortcoming of this retarded world - no zippers. I did not appreciate zippers until I no longer had them.)

I took a deep breath, then lowered my trousers a few inches. 'Is that enough?'

'A little more, please - and will you please turn your back to me?'

I did as she asked. Then I felt her hands, gentle and not invasive, at my right rear. She lifted a shirttail and pulled down the top of my underwear pants on the right.

A moment later she restored both garments. 'That's enough. Thank you.'

I tucked in my shirttails and buttoned up my fly, reshouldered, the braces and reached for the cummerbund. She said, 'Just a moment, Alec.'

'EM I thought you were through.'

'I am. But there is no need to get back into those formal clothes; let me get out casual trousers for you. And shirt. Unless you are going back to the lounge?'

'No. Not if you will stay.'

'I will stay; we must talk.' Quickly she took out casual trousers and a sports shirt for me, laid them on the bed. 'Excuse me, please.' She went into the bath.

I don't know whether she needed to use it or not, but she knew that I could change more comfortably in the stateroom than in that cramped shipboard bathroom.

I changed and felt better. A cummerbund and a boiled shirt are better than a straitjacket but not much. She came out, at once hung up the clothes I had taken off, all but the shirt and collar. She removed studs and collar buttons from these, put them away, and put shirt and collar into my laundry bag. I wondered what Abigail would think if she - could see these wifely attentions. Abigail did not believe in spoiling me - and did not.
