“The Nazis killed all the men over fifteen right off the bat,” Libor told me, without waiting for my reply. “They picked out a handful of very young children who looked German and sent those off to be raised as good little Nazis. Then they shipped the women and the rest of the children to concentration camps. They killed all the livestock and all the pets in the village. They looted the village, down to digging up the cemetery, hunting for gold teeth or jewelry. When they were done, they burned the buildings. When that wasn’t complete enough for them, they blew it up. They covered the whole thing with topsoil and planted it. The roads that led in and out of town were rerouted, as was a stream. When they finished, there was no sign that Lidice had ever existed there.”

Delenda est Carthago, said the ghost, just before Libor said the same thing.

“When the Romans destroyed Carthage, they leveled it so not one stone stood upon another,” Libor continued. “Lidice was a multilevel message from the Nazis. The first message was to those under their rule, that any assassination would be punished, and punishment would not just fall on the conspirators but on their families. Second, to the German people, that Heydrich was properly avenged and that it was Czech rebels, not Hitler, who engineered his death. Heydrich was being groomed or grooming himself, accounts vary, to take over the Third Reich from Hitler. Heydrich, unlike Hitler, was tall, blond, athletic, and smart. The German ideal, in fact—which Hitler himself was not.”

Had we killed Heydrich? They asked me, said Danek’s ghost. How could I tell the Nazis that? They would have killed me, too, even though I was working for them. They would have asked why I had not warned them. If I told them nothing, they would have suspected me. So I gave them something else. A rumor, I said, that the assassins came from a little village. They didn’t need the real assassins if they had a village to punish. Lidice didn’t die for a lie. For my lie. Not really. It died so we could go on fighting the Nazis. We won. We beat them. I did the right thing. For Prague. For the resistance.

The other ghosts, including the woman who must, from his description and her behavior, have been Libor’s wife, were backing away from Danek, as if something about him was repellent to other ghosts. They drifted, almost casually, through the walls until, by the end of Danek’s self-justification speech, the only ghost in the garden was Danek’s.

I was working really hard at keeping a calm facade. I’d never done anything like this. I was pretty sure that I should have kept on following my brother’s advice instead of giving in to my temper when Libor pushed me.

“We killed Danek when we found out what he had done,” Libor said. “He knew what the Nazis would do, and he gave them a random target that was away from him. A village small enough to destroy—because that’s what Hitler wanted.”
