'What waz that all about Margrethe?'

'I had to see something. Alec, you were wondering what had become of Alec Graham. I now know the answer.'

'Yes?'

'He's right here. You are he.'

At last I said, 'That, just from looking at a few square inches on my behind? What did you find, Margrethe? The strawberry mark that identifies the missing heir?'

'No, Alec. Your "Southern Cross".'

'My what?'

'Please, Alec. I had hoped that it would restore your, memory. I saw it the first night we -' She hesitated, then looked me square in the eye.'- made love. You turned on the light, then turned over on your belly to see what time it was. That was when I noticed the moles on your right buttock cheek. I commented on the pattern. they made, and we joked about it. You said that it was your Southern Cross and it let you know which end was up. '

Margrethe turned slightly pink but continued to look me firmly in the eye. 'And I showed you some moles on my body. Alec, I am sorry that you do not remember it but please believe me: By then we were well enough acquainted that we could be playful about such things without my being forward or rude.'

'Margrethe, I don't think you could ever be forward or rude. But you're putting too much importance on a chance arrangement of moles. I've got moles all over me; it doesn't surprise me that some of them, back where I can't see easily, are arranged in a cross shape. Or that Graham` had some that were somewhat similar.'

'Not "similar". Exactly the same.'

'Well - There is a much better way to check. In the desk there is my wallet. Graham's wallet, actually. Driver's license. His. His thumbprint on it. I haven't checked it because I have never had the slightest doubt that he was Graham and that I am Hergensheimer and that we are not the same man. But we can check. Get it out, dear. Check it yourself. I'll put a thumbprint on the mirror in the bath. Compare them. Then you will know.'

'Alec, I do know. You are the one who doesn't believe it; you check it.'

'Well -' Margrethe's counterproposal was reasonable; I agreed to it.

I got out Graham's driver's license, then placed a print on the bath mirror by first rubbing my thumb over my nose for the nose's natural oil, so much greater than that of the pad of the thumb. I found that I could not see the pattern on the glass too well, so I shook a little talcum onto my palm, blew it toward the mirror.

Worse. The powder that detectives use must be much finer than shaving talcum. Or perhaps I don't know how to use it. I placed another print without powder, looked at both prints, at my right thumb, at the print on the driver's license, then checked to see that the license did indeed designate print of right thumb. It did. 'Margrethe! Will you come look, please?'

She joined me in the bath. 'Look at this,' I said. 'Look at all four - my thumb and three prints. The pattern in all four is basically an arch - but that simply trims it down to half the thumbprints in the world. I'll bet you even money that your own thumbprints have an arch pattern. Honest, can you tell whether or not the thumbprint on the card--was made by this thumb? Or by my left thumb; they might have made a mistake.'

'I cannot tell, Alec. I have no skill in this.'

'Well - I don't think even an expert could tell in this light. We'll have to put it off till morning; we need bright sunlight out on deck. We also need glossy white paper, stamp-pad ink, and a magnifying glass ... and I'll bet Mr Henderson will have all three. Will tomorrow do?'

'Certainly. This test is not for me, Alec; I already know in my heart. And by seeing your "Southern Cross". Something has happened to your memory but you are still you... and someday we will find your memory again.'

'It's not that easy, dear. I know that I am not Graham.

Margrethe, do you have any idea what business he was in? Or why he was on this trip?'

'Must I say "him"? I did not ask your business, Alec. And you never, offered to tell me.'

'Yes, I think you must say "him", at least until we check that thumbprint. Was he married?'

'Again, he did not say and I did not ask.'

'But you implied - No, you flatly stated that you had "made love" with this man whom you believe to be me, and that you have been in bed with him.'

'Alec, are you reproaching me?'

'Oh, no, no, no!' (But I was, and she knew it.) 'Whom you go to bed with is your business. But I must tell you that I am married.'

She shut her face against me. 'Alec, I did not try to seduce you into marriage.'

'Graham, you mean. I was not there.'

'Very well. Graham. I did not entrap Alec Graham. For our mutual happiness we made love. Matrimony was not mentioned by either of us.'

'Look, I'm sorry I mentioned the matter! It seemed to have some bearing on the mystery; that's all. Margrethe, will you believe that, I would rather strike off my arm - or pluck out my eye and cast it from me - than hurt you, ever, in any way?'

'Thank you, Alec. I believe you.'

'All that Jesus ever said was: "Go, and sin no more.' Surely you do not think I would ever set myself up as more severely judgmental than was Jesus? But I was not judging you; I was seeking information about Graham. His business, in particular. Uh, did you ever suspect that he might be engaged in something illegal?'

She gave a ghost of a smile. 'Had I ever suspected anything of the sort, my loyalty to him is such that I would never express such suspicion. Since you insist that you are not he, then there it must stand.'

'Touch~!' I grinned sheepishly. Could I tell her about the lockbox? Yes, I must. I had to be frank with her and had to persuade her that she was not being disloyal to Graham/me were she to be equally frank. 'Margrethe, I was not asking idly and I was not prying where I had no business to pry. I have still more, trouble and I need your advice.'

Her turn to be startled. 'Alec... I do not often give advice. I do not like to.'

'May I tell you my trouble? You need not advise me... but perhaps you may be able to analyze it for me.' I told her quickly about that truly damning million dollars. 'Margrethe, can you think of any legitimate reason why an honest man would be carrying a million dollars in cash? Travelers checks, letters of credit, drafts for transferring monies, even bearer bonds - But cash? In that amount? I say that it is psychologically as unbelievable as what happened to me in the fire pit is physically unbelievable. Can you see any other way to look at it? For what honest reason would a man carry that much cash on a trip like this?'

'I will not pass judgment.'

'I do not ask you to judge; I ask you to stretch your imagination and tell me why a man would carry with him a million dollars in cash. Can you think of a reason? One as farfetched as you like... but a reason.'

'There could be many reasons.'

'Can you think of one?'

I waited; she remained silent. I sighed and said, 'I can't think of one, either. Plenty of criminal reasons, of course, as so-called "hot money" almost always moves as cash. This is so common that most governments - all governments, I believe - assume that any large amount of cash being moved other than by a bank or by a government is indeed crime money until proved otherwise. Or counterfeit money, a still more depressing idea. The advice I need is this: Margrethe, what should I do with it? It's not mine; I can't take it off the ship. For the same reason I can't abandon it. I can't even throw it overboard. What can I do with it?'

My question was not rhetorical; I had to find an answer that would not cause me to wind up in jail for something Graham had done. So far, the only answer I could think of was to go to the only authority in the ship, the Captain, tell him all my troubles and ask him to take custody of that awkward million dollars.
