by lot number, for thousands of the combination locks manufactured in Europe since 1900.
For weeks, Josef pleaded with Kornblum to be allowed to handle a pick himself. Contrary to instructions, he had been working over the locks at home with a hat pin and a spoke from a bicycle wheel, with occasional success.
“Very well,” said Kornblum at last. Handing Josef his pick and a torque wrench, he led him to the door of his room, in which he had himself installed a fine new Rätsel seven-pin lock. Then he unknotted his necktie and used it to blindfold Josef. “To see inside the lock, you don’t use your eyes.”
Josef knelt down in darkness and felt for the brass-plated knob. The door was cold against his cheek. When at last Kornblum removed the blindfold and motioned for Josef to climb into the coffin, Josef had picked the Rätsel three times, the last in under ten minutes.
On the day before Josef caused a disturbance at the breakfast table, after months of nauseous breathing drills that made his head tingle and of practice that left the joints of his fingers aching, he had walked into Kornblum’s room and held out his wrists, as usual, to be cuffed and bound. Kornblum startled him with a rare smile. He handed Josef a small black leather pouch. Unrolling it, Josef found the tiny torque wrench and a set of steel picks, some no longer than the wrench, sometwice as long with smooth wooden handles. None was thicker than a broom straw. Their tips had been cut and bent into all manner of cunning moons, diamonds, and tildes.
“I made these,” said Kornblum. “They will be reliable.”
“For me? You made these for me?”
“This is what we will now determine,” Kornblum said. He pointed to the bed, where he had laid out a pair of brand-new German handcuffs and his best American Yale locks. “Chain me to the chair.”
Kornblum allowed himself to be bound to the legs of his chair with a length of heavy chain; other chains secured the chair to the radiator, and the radiator to his neck. His hands were also cuffed—in front of his body, so that he could smoke. Without a word of advice or complaint from Kornblum, Josef got the handcuffs and all but one of the locks off in the first hour. But the last lock, a one-pound 1927 Yale Dreadnought, with sixteen pins and drivers, frustrated his efforts. Josef sweated and cursed under his breath, in Czech, so as not to offend his master. Kornblum lit another Sobranie.
“The pins have voices,” he reminded Josef at last. “The pick is a tiny telephone wire. The tips of your fingers have ears.”
Josef took a deep breath, slid the pick that was tipped with a small squiggle into the plug of the lock, and again applied the wrench. Quickly, he stroked the tip of the pick back and forth across the pins, feeling each one give in its turn, gauging the resistance of the drivers and springs. Each lock had its own point of equilibrium between torque and friction; if you turned too hard, the plug would jam; too softly, and the pins wouldn’t catch properly. With sixteen-pin columns, finding the point of equilibrium was entirely a matter of intuition and style. Josef closed his eyes. He heard the wire of the pick humming in his fingertips.
With a satisfying metallic gurgle, the lock sprang open. Kornblum nodded, stood up, stretched.
“You may keep the tools,” he said.
However slow the progress of the lessons with Herr Kornblum had seemed to Josef, it had come ten times slower for Thomas Kavalier. The endless tinkering with locks and knots that Thomas had covertly witnessed, night after night, in the faint lamplight of the bedroom the boysshared, was far less interesting to him than Josef’s interest in coin tricks and card magic had been.
Thomas Masaryk Kavalier was an animated gnome of a boy with a thick black thatch of hair. When he was a very young boy, the musical chromosome of his mother’s family had made itself plain in him. At three, he regaled dinner guests with long,
