‘But to come back to the traitor X: as you know, all of the guests in this house were under suspicion in that respect. However, by a simple process of elimination our intelligence analysts had narrowed down the search for the traitor’s identity to one of six or seven officers. Consequently everything these men said on the least of subjects was of interest to us. Which is why some of the rooms in the Lower Castle have concealed microphones, just in case one of them should let something important slip.’
‘You mean, like the Pension Matzky.’
Heydrich nodded. ‘You know about the microphones, do you?’ He grinned. ‘Yes, like the Pension Matzky.’
‘And do these rooms here include the Morning Room?’
‘Yes, they do.’
My stomach turned over for a moment; not for my own sake – as far as Heydrich was concerned, I was a hopeless case – but for Kurt Kahlo’s, and I started to rack my brains for anything he had said that might have been interpreted as evidence of his disloyalty.
‘So you’ve heard everything that was said in there?’
‘No, not me personally. But I’ve read some of the transcripts.’
‘Kuttner’s room?’
‘No. My fourth adjutant was hardly important enough to have rated that level of surveillance.’ Heydrich made a face. ‘Which is a pity, because if he had been, then of course we would now know who it was who pumped two bullets into his chest.’
I let out a weary sigh and tried to put some sort of tolerant, understanding face on what had just been revealed to me.
‘In my book, a traitor is a traitor. I can easily see why you should wish to employ every method at your disposal in order to catch him. Including secret microphones. But I just hope you’ll excuse some of my Criminal Assistant Kahlo’s looser talk in the Morning Room. You can blame me for a lot of that. He’s a good man. I’m afraid I’ve been a bad influence on him.’
‘On the contrary, Gunther. It’s thanks to you and your unconventional, not to say insubordinate methods, that the traitor has now been revealed. In fact, everything has worked out exactly as I had hoped it would. You, Gunther, have been the catalyst that changed everything. I don’t know who to congratulate more: me for having the inspiration of bringing you here in the first place, or you for your own stubbornly independent cast of mind.’
I felt my face take on an expression of disbelief.
‘Yes, it’s quite true. It seems that we owe you everything in this matter, Gunther. Which makes it all the more unfortunate that your immediate reward should have been to be knocked unconscious by one of our more robust colleagues in the SD. For which, once again, I offer my sincere apologies. You were after all merely doing your job. A job well done. For even as we speak the traitor is under close arrest and on his way to Gestapo headquarters in Prague.’
‘But who was it? The traitor.’
‘It was Major Thummel. Paul Thummel, of the Abwehr.’
‘Thummel. He’s a man with a gold Party badge, isn’t he?’
‘I did say it would turn out to be someone who was apparently above reasonable suspicion.’
‘But he’s also a friend of Himmler.’
Heydrich smiled. ‘Yes. And that is something of a bonus. The acute embarrassment that this particular association will cause the Reichsführer will be a great pleasure to behold. I can’t wait to see Himmler’s face when I tell the Leader. For that same reason, however, it’s by no means certain that we’ll make any of this stick against Thummel. We shall, of course, do our best.’
I nodded. ‘I’m beginning to understand. It has something to do with that letter I received this morning from the Netherlands, doesn’t it?’
‘It does indeed. You asked Major Thummel if he was the same Captain Thummel who was in The Hague in 1939. He denied it, of course. Now why? Why would that be of any interest to you? But this was a lie. It was a matter of only a few minutes to check through a record of his military service. When Thummel was a captain in 1939, he passed through The Hague on his way to Paris. We know he was in The Hague because he visited our military attaché at the German Embassy. But while he was in The Hague we also think he met secretly with his Czech controller, a man named Major Franck. Franck and Thummel shared a Dutch girlfriend named Inge Vranken. I shall want to see your letter of course, but it rather looks as if Inge Vranken was your friend Geert’s little sister.
‘We suspect Thummel has been spying for the Czechos since as early as February 1936. For a long time he was using a radio transmitter to send messages here, to Prague. As you are aware we were intercepting some of that radio traffic; what we called the OTA intercepts. The Czechos called him A54. Don’t ask me why. Call sign probably. The radio messages were forwarded by courier to the Czech government in exile in London. That went on for quite a while. But then Thummel began to get scared. He stopped using the radio transmitter altogether. And to all intents and purposes it looked as if he had closed up shop, thus narrowing our chances of getting him.
