trial came up again for me recently, as well. That’s why I’m glad to be able to talk to you. In San Francisco I met the partner of the late prosecution witness Professor Weinstein and discovered his testimony was false. Someone from the Works and an SS officer put pressure on him. Do you have any idea, or do you even know who could have had an interest in your and Dohmke’s disappearance? I hate to have been used as the tool of unknown interests.’
Tyberg rang a bell, the butler appeared, tidied up, and served sherry. Tyberg sat there, frowning, staring into space. ‘I started pondering this in prison while I was awaiting trial, and to this day I have found no answer. Time and again I’ve thought of Weismüller. That was also the reason I didn’t want to return to RCW immediately after the war. But I’ve no confirmation for this notion. I’ve also been preoccupied for a long time by how Weinstein could have given that testimony. That he made it to my desk, found the manuscript in the drawer, misinterpreted it, and reported me, I found devastating enough. But his testimony about a conversation between Dohmke and myself that never took place was even more devastating. I wondered if it was all for a few advantages at the camp. Now I hear he was forced. It must have been terrible for him. Did his partner know and tell you that he tried to contact me after the war, and I refused? I was too hurt and he must have been too proud to tell me in his letter about the pressure he’d been under.’
‘What happened to your research at the RCW, Herr Tyberg?’
‘Korten kept going with it. It was the result anyway of close cooperation between Korten, Dohmke, and myself. The three of us had also made the decision together that we would only pursue the one path to begin with, and put the other on the backburner. The whole thing was our baby, you see, that we jealously hatched and tended and didn’t let anyone near. We didn’t even let Weinstein into our confidence although he was an important part of our team, scientifically almost on equal footing. But you wanted to know what happened to our research. Since the oil crisis I wonder sometimes if it won’t become highly topical again all of a sudden. Fuel synthesis. We’d gone at it a different way from Bergius, Tropsch, and Fischer because from the outset we attributed great significance to the cost factor. Korten continued the development of our process with great dedication, and readied it for production. That work was, quite rightly, the basis of his swift ascent in the RCW even though after the end of the war the process itself was no longer of importance. Korten, I believe, had it patented, though, as the Dohmke-Korten-Tyberg process.’
‘I don’t know if you realize how dreadful I feel that Dohmke was hanged; and equally how happy I am that you managed to escape. It’s mere curiosity, of course, but would you mind telling me how you did it?’
‘That’s sort of a long story. I want to tell you, but . . . you will stay for dinner, won’t you? How about afterwards? I’ll just let them know so the butler can prepare the food and make a fire. And until then . . . Do you play an instrument, Herr Self?’
‘The flute, but I haven’t had any time to play all summer and autumn.’
He stood up, fetched a flute case from the Biedermeier cupboard and had me open it. ‘Do you think you can play this?’ It was a Buffet. I put it together and played a few scales. It had a wonderfully soft, yet clear tone, jubilant in the high reaches, in spite of my bad intonation after the long break. ‘Do you like Bach? How about the Suite in B minor?’
We played until dinner, after the Suite in B minor, Mozart’s Concerto in D major. He played the piano confidently and with great expression. I had to bluff my way through some of the fast passages. At the end of the pieces Judith laid her knitting aside and clapped.
We ate duck with chestnut stuffing, dumplings, and red cabbage. The wine was new to me, a fruity Merlot from Tessin. By the fire, Tyberg asked us to keep his story to ourselves. It would be made public soon, but until then discretion would be appreciated. ‘I
