‘But you look tired,’ said a third voice, which I took to be Kindermann’s. ‘You’d better let me take a look at you.’

I edged forward and looked through the gap between the cloakroom door and frame, Weisthor was taking off his jacket and hanging it over the back of a chair. Sitting down heavily, he allowed Kindermann to take his pulse. He seemed listless and pale, almost as if he really had been in contact with the spirit world. He seemed to hear my thoughts.

‘Faking it is almost as tiring as doing it for real,’ he said.

‘Perhaps I should give you an injection,’ said Kindermann. ‘A little morphine to help you sleep.’ Without waiting for a reply he produced a small bottle and a hypodermic syringe from a medical bag, and set about preparing the needle. ‘After all, we don’t want you feeling tired for the forthcoming Court of Honour, do we?’

‘I shall want you there of course, Lanz,’ said Weisthor, rolling back his own sleeve to reveal a forearm that was so bruised and scarred with puncture marks, that it looked as if he had been tattooed.

‘I shan’t be able to get through it without cocaine. I find it clarifies the mind wonderfully. And I shall need to be so transcendentally stimulated that the Reichsführer-SS will find what I have to say totally irresistible.’

‘You know, for a moment back there I thought you were actually going to make the revelation tonight,’ said Rahn. ‘You really teased him with all of that stuff about the girl not wanting to get anyone into trouble. Well, frankly, he more or less believes it now.’

‘Only when the time is right, my dear Otto,’ said Weisthor. ‘Only when the time is right. Think how much more dramatic it will be to him when I reveal it in Wewelsburg. Jewish complicity will have the force of spiritual revelation, and we will be done with this nonsense of his about respecting property and the rule of law. The Jews will get what’s coming to them and there won’t be one policeman to stop it.’ He nodded at the syringe and watched impassively as Kindermann thrust the needle home, sighing with satisfaction as the plunger was depressed.

‘And now, gentlemen, if you will kindly help an old man to his bed.’

I watched as they each took an arm and walked him up the creaking stairs.
