He climbed off the high scaffolding with the agility of a house cat and dropped silently onto the stone floor of the chapel. A knot of tourists had been watching him work for several minutes. As a rule the restorer did not like spectators-indeed, some days he shrouded the platform in a gray tarpaulin. Tonight’s crowd dispersed as he pulled on a reefer coat and woolen watch cap. Softly, he bid them buona sera, instinctively recording each face in his mind, as permanently as if they were rendered with oil on canvas.

An attractive German girl tried to engage him in conversation. She spoke to him in poor Italian. In rapid, Berlin-accented German-his mother had lived in Charlottenburg before the war-the restorer said he was late for an appointment and could not talk now. German girls made him uneasy. Reflexively his eyes wandered over her-across her large, rounded breasts, up and down her long legs. She mistook his attention for flirting, tilted her head, smiled at him through a lock of flaxen hair, suggested a coffee in the café across the square. The restorer apologized and said he had to leave. “Besides,” he said, looking up at the soaring nave, “this is Stephansdom, Fraülein. Not a pickup bar.”

A moment later he passed through the entrance of the cathedral and struck out across the Stephansplatz. He was of medium height, well below six feet. His black hair was shot with gray at the temples. His nose was rather long and angular, with sharp edges across the bridge that left the suggestion it had been carved from wood. Full lips, cleft chin, cheekbones broad and square. There was a hint of the Russian steppes in his eyes-almond shaped, unnaturally green, very quick. His vision was perfect, despite the demanding nature of his work. He had a confident walk, not an arrogant swagger or a march but a crisp, purposeful stride that seemed to propel him effortlessly across the snowbound square. The box containing his paints and brushes was under his left arm, resting on the metal object that he wore, habitually, on his left hip.
