The Slav, not much taller than the piano tuner but far stronger, took him by the shoulders. “Sit,” he whispered gently, pushing the man down on the bench then turning him to face the piano.

“What do you want?” A quaking voice, tears in his eyes.

“Shhh.”

Shaking with fear, the piano tuner thought madly, What a fool I am! I should have fled the moment the man commented on the Bosendorfer’s German ancestry. Anyone with a true understanding of the keyboard knew the instruments are made in Austria.

When he was stopped at Krakow’s John Paul II airport, he was certain his offense had to do with what he carried in his briefcase.

The hour was early and he’d wakened much earlier at the Pod Roza, “Under the Rose,” which was his favorite hotel in Poland, owing both to its quirky mix of scrolly ancient and starkly modern, and to the fact that Franz Liszt had stayed there. Still half asleep, without his morning coffee or tea, he was startled from his stupor by the two uniformed men who appeared over him.

“Mr. Harold Middleton?”

He looked up. “Yes, that’s me.” And suddenly realized what had happened. When airport security had looked through his attaché case, they’d seen it and grown concerned. But out of prudence the young guards there had chosen not to say anything. They let him pass, then called for reinforcements: these two large, unsmiling men.

Of the twenty or so passengers in the lounge awaiting the bus to take them to the Lufthansa flight to Paris, some people looked his way—the younger ones. The older, tempered by the Soviet regime, dared not. The man closest to Middleton, two chairs away, glanced up involuntarily with a flash of ambiguous concern on his face, as if he might be mistaken as his companion. Then, realizing he wasn’t going to be questioned, he turned back to his newspaper, obviously relieved.

“You will please to come with us. This way. Yes. Please.” Infinitely polite, the massive guard nodded back toward the security line.

“Look, I know what this is about. It’s simply a misunderstanding.” He larded his voice with patience, respect and good nature. It was the tone you had to take with local police, the tone you used talking your way through border crossings. Middleton nodded at the briefcase. “I can show you some documentation that—”

The second, silent guard picked up the case.

The other: “Please. You will come.” Polite but inflexible. This young, square-jawed man who seemed incapable of smiling held his eye firmly and there was no debate. The Poles, Middleton knew, had been the most willful resisters of the Nazis.
