The face was long and narrow at the chin, with wide cheekbones and a slender nose that looked as though it had been carved from wood. The eyes were an unnatural shade of green; the hair was dark and shot with gray at the temples. It was a face of many possible origins, and the restorer possessed the linguistic gifts to put it to good use. Over the course of a long career, he had worked in Italy and elsewhere under numerous pseudonyms and nationalities. The Italian security services, aware of his past exploits, had tried to prevent his entry into the country but had relented after the quiet intervention of the Holy See. For reasons never made public, the restorer had been present at the Vatican several years earlier when it was attacked by Islamic terrorists. More than seven hundred people were killed that day, including four cardinals and eight Curial bishops. The Holy Father himself had been slightly wounded. He might very well have been among the dead had the restorer not shielded him from a shoulder-fired missile and then carried him to safety.

The Italians had imposed two conditions upon the restorer’s return-that he reside in the country under his real name and that he tolerate the presence of occasional physical surveillance. The first he accepted with a certain relief, for after a lifetime on the secret battlefield he was anxious to shed his many aliases and to assume something of a normal life. The second condition, however, had proved more burdensome. The task of following him invariably fell to young trainees. Initially, the restorer had taken mild professional offense until he realized he was being used as the subject of a daily master class in the techniques of street surveillance. He obliged his students by evading them from time to time, always keeping a few of his better moves in reserve lest he find himself in circumstances that required slipping the Italian net.
