‘Be careful, sir,’ he said as he got behind the driving wheel and started the engine. I told him not to worry.

After they had driven away, I waited in the car for half an hour or so, and then walked back down Caspar-Theyss Strasse. The wind was getting up a bit and a couple of times it rose to such a pitch in the trees that lined the dark street that, had I been of a rather more fanciful disposition, I might have imagined that it was something to do with what had taken place in Weisthor’s house. Disturbing the spirits and that sort of thing. As it was I was possessed of a sense of danger which the wind moaning across the cloud-tumbling sky did nothing to alleviate, and indeed, this feeling was if anything made all the more acute by seeing the gingerbread house again.

By now the staff cars were gone from the pavement outside, but I nevertheless approached the garden with caution, in case the two SS men had remained behind, for whatever reason. Having satisfied myself that the house was not guarded, I tiptoed round to the side of the house, and to the lavatory window I had left unlocked. It was well that I stepped lightly, because the light was on and from inside the small room could be heard the unmistakable sound of a man straining on the toilet-bowl. Flattening myself in the shadows against the wall, I waited until he finished, and finally, after what seemed like ten or fifteen minutes, I heard the sound of the toilet flushing, and saw the light go off.

Several minutes passed before I judged it safe to go to the window and push it up the sash. But almost immediately upon entering the lavatory, I could have wished to have been elsewhere, or at least wearing a gas-mask, since the fecal smell that greeted my nostrils was such as would have turned the stomachs of a whole clinicful of proctologists. I suppose that’s what bulls mean when they say that sometimes it’s a rotten job. For my money, having to stand quietly in a toilet where someone has just achieved a bowel-movement of truly Gothic proportions is about as rotten as it can get.

The terrible smell was the main reason I decided to move out into the cloakroom rather more quickly than might have been safe, and I was almost seen by Weisthor himself as he trudged wearily past the open cloakroom door and across the hallway to a room on the opposite side.

‘Quite a wind tonight,’ said a voice, which I recognized as belonging to Otto Rahn.

‘Yes,’ Weisthor chuckled. ‘It all added to the atmosphere, didn’t it? Himmler will be especially pleased with this turn in the weather. No doubt he will ascribe all sorts of supernatural Wagnerian notions to it.’

‘You were very good, Karl,’ said Rahn. ‘Even the Reichsfuhrer commented on it.’
