We had enough of that during the Ogorzow case. Everyone in Berlin was convinced that a German couldn’t possibly have murdered all those women. A lot of foreign workers were harassed and beaten up by irate Berliners who thought that one of them must have done it. You don’t want to see any more of that, do you? Christ, there are problems enough on the trains and the underground as it is. It took me almost an hour to come to work this morning.’

‘I wonder why we bother to come in at all given that the Ministry of Propaganda is now deciding what we can and what we can’t investigate. Are we really supposed to find people who look Jewish and check to see if they’re wearing the right embroidery? It’s laughable.’

‘I’m afraid that’s just how it is. Perhaps if there are any more stabbings like this one then we can devote some resources to an investigation, but for now I’d rather you left this Dutchy alone.’

‘All right, Wilhelm, if that’s the way you want it.’ I bit hard on my match. ‘But I’m beginning to understand your twenty-a-day match habit. I guess it’s easier not to scream when you’re chewing down on one of these.’

As I stood up to leave I glanced up at the picture on the wall. The Leader stared me down in triumph but, for a change, he wasn’t saying very much. If anyone needed a yellow star it was him; and sewn just over his heart, assuming he had one; an aiming spot for a firing squad.

The Berlin city map on Ludtke’s wall told me nothing either. When Bernhard Weiss, one of Ludtke’s predecessors, had been in charge of Berlin Kripo, the map had been covered with little flags marking the incidents of crime in the city. Now it was empty. There was, it seemed, no crime to speak of. Another great victory for National Socialism.

‘Oh, by the way. Shouldn’t someone tell the Vranken family back in Holland that their major breadwinner stopped a train with his face?’
