‘This is Kommissar Gunther,’ I said to the operator at the Alex. ‘Connect me with Kriminalassistant Korsch or Becker in the Murder Commission as quickly as possible, if you please.’ After another short wait Becker came on to the line.

‘I’m at Kindermann’s clinic,’ I explained. ‘We stopped to pick up the medical case history on Weisthor and Lange managed to get himself killed. He lost his temper and a piece of his neck. Kindermann was carrying a lighter.’

‘Want me to organize the meat wagon?’

‘That’s the general idea, yes. Only I won’t be here when it comes. I’m sticking to my original plan, except that now I’m taking Kindermann along with me instead of Lange.’

‘All right, sir. Leave it to me. Oh, incidentally, Frau Steininger called.’

‘Did she leave a message?’

‘No, sir.’

‘Nothing at all?’

‘No, sir. Sir, you know what that one needs, if you don’t mind me saying?’

‘Try and surprise me.’

‘I reckon that she needs–’

‘On second thoughts, don’t bother.’

‘Well, you know the type, sir.’

‘Not exactly, Becker, no. But while I’m driving I’ll certainly give it some thought. You can depend on it.’

I drove west out of Berlin, following the yellow signs indicating long-distance traffic, heading towards Potsdam and beyond it, to Hanover.

The autobahn branches off from the Berlin circular road at Lehnin, leaving the old town of Brandenburg to the north, and beyond Zeisar, the ancient town of the Bishops of Brandenburg, the road runs west in a straight line.

After a while I was aware of Kindermann sitting upright in the back seat of the Mercedes.

‘Where are we going?’ he said dully.

I glanced over my right shoulder. With his hands manacled behind his back I didn’t think he’d be stupid enough to try hitting me with his head. Especially now it was bandaged, something the two nurses from the clinic had insisted on doing before allowing me to drive the doctor away.

‘Don’t you recognize the road?’ I said. ‘We’re on our way to a little town south of Paderborn. Wewelsburg. I’m sure you know it. I didn’t think you would want to miss your S S Court of Honour on my account.’ Out of the corner of my eye I saw him smile and settle back in the rear seat, or at least, as well as he was able to.

‘That suits me fine.’

‘You know, you’ve really inconvenienced me, Herr Doktor. Shooting my star witness like that. He was going to give a special performance for Himmler. It’s lucky he made a written statement back at the Alex. And, of course, you’ll have to understudy.’

He laughed. ‘And what makes you think I’ll take to that role?’

‘I’d hate to think what might happen if you were to disappoint me.’
