nineteen seventy-eight, then registers of our inventions and inventors’ royalties, way back to before nineteen forty-five, and here’s . . . I can’t open it but the abbreviations might also stand for other chemical companies.’ He turned the machine off. ‘I wanted to thank you very much. Firner called me in and said you’d praised me in your report and that he had plans for me.’
I left a happy person behind. For a moment I could picture Tausendmilch, on whose right hand I’d spotted a wedding ring, coming home after work that day and telling his elegant wife, who had a martini ready for him and in her way was contributing to his rise, about his success today.
At security I sought out Thomas. On the wall of his office hung a half-finished plan of the course for security studies. ‘I had something to do in the plant and wanted to discuss your kind offer of a teaching appointment. To what do I owe the honour?’
‘I was impressed by how you solved our data-security problem. You taught us some things here, Oelmüller in particular. And it would be indispensable for the curriculum to have a freelancer involved.’
‘What would be the subject?’
‘The detective’s work: from the practical to the ethical. With seminars and a final exam if that’s not too much trouble. The whole thing should start in the winter term.’
‘I see a problem there, Herr Thomas. According to your concept, and it also seems sensible to me, I can only teach the students by using my experience with real cases. But think of the business here at the Works we were just discussing. Even if I didn’t mention any names and I went to lengths to disguise the whole thing a bit, it would be a case of the king’s birthday suit.’
Thomas didn’t get it. ‘Do you mean Herr King in export coordination? But he doesn’t have a birthday suit. And besides—’
‘You still had some trouble with the case, Firner told me.’
‘Yes, things were a bit tough with Mischkey.’
‘Should I have been harsher?’
‘He was rather uncooperative when you left him with us.’
‘After everything I heard from Firner he was given the kid-glove treatment. No talk of police and court and prison – that would only encourage a lack of cooperation.’
‘But Herr Self, we didn’t tell him that. The problem lay elsewhere. He virtually tried to blackmail us. We never found out whether he really had something up his sleeve, but he made some noise.’
‘With the same old stories?’
‘Yes, with the same old stories. Threatening to go to the press, to the competition, to the union, to the plant authorities, to the Federal Antitrust Office. You know, it’s tough to say this, and I’m sorry about Mischkey’s death, but at the same time I’m happy not to be burdened with this problem any more.’
Danckelmann came in without knocking. ‘Ah, Herr Self, you’ve been the topic of conversation today already. Why are you still involved in this Mischkey business? The case is long since closed. Don’t go rattling cages.’
Just as I had been when talking to Thomas, I was on thin ice with Danckelmann. Questions that were too direct could make it crack. But nothing ventured, nothing gained. ‘Did Grimm call you?’
Danckelmann ignored my question. ‘Seriously, Herr Self, keep your nose out of this story. We don’t appreciate it.’
‘For me, cases are only over when I know everything. Did you know, for example, that Mischkey took another stroll around your system?’
Thomas pricked up his ears and looked disconcerted. He was already regretting his offer of a teaching appointment.
Danckelmann controlled himself and his voice was tight. ‘Curious notion you have of a job. It’s over when the client says it’s over. And Herr Mischkey isn’t strolling anywhere any more. So please . . .’
I’d heard more than I’d dreamed possible and had no interest in a further escalation. Just one more wrong word and Danckelmann would remember my special ID. ‘You’re absolutely right, Herr Danckelmann. On the other hand, you certainly agree that when security is involved, things can’t always be contained within the narrow limits of a job. And don’t worry, being a freelancer, I can’t afford to invest too much without a fee.’
Danckelmann left the room only partially appeased. Thomas was waiting impatiently for me to be gone. But I still had a treat for him. ‘To return to what you were saying, Herr Thomas, I’m happy to accept the teaching appointment. I’ll draw up a curriculum.’
‘Thank you for your interest, Herr
