“Operation Othello was run by Erich Mielke. I’ve known him for years—since before the Nazis came to power when he was just another KPD cadre with a gun and a Lenin cap. Put a lot of weight on since then. I mean, he wouldn’t recognize himself if the Erich Mielke from nineteen thirty-two was to meet today’s Erich Mielke. He murdered a couple of Berlin cops that year and I helped him to get away from the city before he could be arrested. I helped him escape from Berlin to Antwerp, where he and another Communist called Zimmer were smuggled onto a ship to Leningrad, just like your friends Burgess and Maclean. I wasn’t a party member then myself, but I hated the semi-Fascist government of von Papen and was determined to do all I could to stop Mielke from going to the guillotine. Besides, those two cops had it coming. Everyone said so. I also helped him to escape from a French internment camp at Le Vernet in nineteen forty when I was in the SD. I’d been sent there to try and identify him.”

“How does someone who had helped a KPD killer to escape end up working for the SD?”

“The same way that Burgess worked for MI5, I suppose. I was what they used to call a beefsteak Nazi: brown on the outside but red in the middle. Besides, I wasn’t the only Red working for the RSHA. Heinrich Müller—Gestapo Müller—he was a Red, too.”

“What were your duties in the SD?”

“Mostly I worked for General Reinhard Heydrich,” I said. “The so-called Protector of Bohemia. You might say I was a kind of troubleshooter. If I saw any trouble, I shot it.” I smiled at my own little joke. But no one else did.

“And when did you next see Comrade Mielke?”

“He helped me escape from that labor camp in nineteen forty-seven, which was when I did join the party and the Stasi. Yes, he and I—we’ve been looking out for each other for almost twenty-five years. My ex-wife has known him even longer than that because she helped to raise the young Mielke after his real mother died. He’d do anything for Elisabeth, but the same is not true for me. He’s not my friend. You can’t be friends with a man like Comrade General Erich Mielke. He’d shoot me just as soon as have a beer with me. The same as Heydrich, really. Two chips off the same block of dirty ice.”

“Tell us about the tape,” said the monk. “Whose idea was that?”
