When the train reached Leipzig a young SA naval company leader joined our compartment, and Korsch and I went in search of the dining car. By the time we had finished eating the train was in Gera, close to the Czech border, but despite the fact that our SA travelling companion got off at that stop, there was no sign of the troop concentrations we had heard about. Korsch suggested that the naval SA man’s presence there meant that there was going to be an amphibious attack, and this, we both agreed, would be the best thing for everyone, given that the border was largely mountainous.

It was early evening by the time that the train got into the Haupt Station in central Nuremberg. Outside, by the equestrian statue of some unknown aristocrat, we caught a taxi which drove us eastwards along Frauentorgraben and parallel to the walls of the old city. These are as high as seven or eight metres, and dominated at intervals by big square towers. This huge medieval wall, and a great, dry, grassy moat that is as wide as thirty metres, help to distinguish the old Nuremberg from the new, which, with a singular lack of obtrusion, surrounds it.

Our hotel was the Deutscher Hof, one of the city’s oldest and best, and our rooms commanded excellent views across the wall to the steep, pitched rooftops and regiments of chimney-pots which lay beyond.

At the beginning of the eighteenth century, Nuremberg was the largest city in the ancient kingdom of Franconia, as well as one of the principal marts of trade between Germany, Venice and the East. It was still the chief commercial and manufacturing city of southern Germany, but now it had a new importance, as the capital of National Socialism. Every year, Nuremberg played host to the great Party rallies which were the brainchild of Hitler’s architect, Speer.

As thoughtful as the Nazis were, naturally you didn’t have to go to Nuremberg to see one of these over-orchestrated events, and in September people stayed away from cinemas in droves for fear of having to sit through the newsreels which would be made up of virtually nothing else.

By all accounts, sometimes there were as many as a hundred thousand people at the Zeppelin Field to wave their flags. Nuremberg, like any city in Bavaria as I recall, never did offer much in the way of real amusement.

Since we weren’t appointed to meet Martin, the Nuremberg Chief of Police, until ten o’clock the following morning, Korsch and I felt obliged to spend the evening in search of whatever entertainment there was. Especially because Kripo Executive was footing the bill. It was a thought that had particular appeal for Korch.

‘This isn’t bad at all,’ he said enthusiastically. ‘Not only is the Alex paying for me to stay in a cock-smart hotel, but I’m also getting the overtime.’
