whose German was awkward and Czech nonexistent, had been born in a shtetl outside of Vilna and had spent most of his life wandering the provinces of imperial Russia, playing the odeons, barns, and market squares of a thousand small towns and villages. He wore suits of an outdated, pigeon-breasted, Valentino cut. Because his diet consisted in large part of tinned fish—anchovies, smelts, sardines, tunny—his breath often carried a rank marine tang. Although a staunch atheist, he nonetheless kept kosher, avoided work on Saturday, and kept a steel engraving of the Temple Mount on the east wall of his room. Until recently, Josef, then fourteen, had given very little thought to the question of his own Jewishness. He believed—it was enshrined in the Czech constitution—that Jews were merely one of thenumerous ethnic minorities making up the young nation of which Josef was proud to be a son. The coming of Kornblum, with his Baltic smell, his shopworn good manners, his Yiddish, made a strong impression on Josef.
Twice a week that spring and summer and well into the autumn, Josef went to Kornblum’s room on the top floor of a sagging house on Maisel Street, in the Josefov, to be chained to the radiator or tied hand and foot with long coils of thick hempen rope. Kornblum did not at first give him the slightest guidance on how to escape from these constraints.
“You will pay attention,” he said, on the afternoon of Josef’s first lesson, as he shackled Josef to a bentwood chair. “I assure you of this. Also you will get used to the feeling of the chain. The chain is your silk pajamas now. It is your mother’s loving arms.”
Apart from this chair, an iron bedstead, a wardrobe, and the picture of Jerusalem on the east wall, next to the lone window, the room was almost bare. The only beautiful object was a Chinese trunk carved from some kind of tropical wood, as red as raw liver, with thick brass hinges, and a pair of fanciful brass locks in the form of stylized peacocks. The locks opened by a system of tiny levers and springs concealed in the jade eyespots of each peacock’s seven tail feathers. The magician pushed the fourteen jade buttons in a certain order that seemed to change each time he went to open the chest.
For the first few sessions, Kornblum merely showed Josef different kinds of locks that he took out, one by one, from the chest; locks used to secure manacles, mailboxes, and ladies’ diaries; warded and pin-tumbler door locks; sturdy padlocks; and combination locks taken from strongboxes and safes. Wordlessly, he would take each of the locks apart, using a screwdriver, then reassemble them. Toward the end of the hour, still without freeing Josef, he talked about the rudiments of breath control. At last, in the final minutes of the lesson, he would unchain the boy, only to stuff him into a plain pine box. He would sit on the closed lid, drinking tea and glancing at his pocket watch, until the lesson was over.
“If you are a claustrophobe,” Kornblum explained, “we must detect this now, and not when you lie in chains at the bottom of the Moldau,strapped inside a postman’s bag, with all your family and neighbors waiting for you to swim out.”
At the start of the second month, he introduced the pick and the torque wrench, and set about applying these wonderful tools to each of the various sample locks he kept in the chest. His touch was deft and, though he was well past sixty, his hands steady. He would pick the locks, and then, for Josef’s further edification, take them apart and pick them again with the works exposed. The locks, whether new or antique, English, German, Chinese, or American, did not resist his tinkerings for more than a few seconds. He had, in addition, amassed a small library of thick, dusty volumes, many illegal or banned, some of them imprinted with the seal of the Bolsheviks’ dreaded Cheka, in which were listed, in infinite columns of minuscule type, the combination formulae,
