Though the stranger did not know it, two disparate series of events were by that night already conspiring to lure him back onto the field of battle. One was being played out behind the locked doors of the world's secret intelligence services while the other was the subject of a global media frenzy. The newspapers had dubbed it "the summer of theft," the worst epidemic of art heists to sweep Europe in a generation. Across the Continent, priceless paintings were disappearing like postcards plucked from the rack of a sidewalk kiosk. The anguished masters of the art universe had professed shock over the rash of robberies, though the true professionals inside law enforcement admitted it was small wonder there were any paintings left to steal. "If you nail a hundred million dollars to a poorly guarded wall," said one beleaguered official from Interpol, "it's only a matter of time before a determined thief will try to walk away with it."

The brazenness of the criminals was matched only by their competence. That they were skilled was beyond question. But what the police admired most about their opponents was their iron discipline. There were no leaks, no signs of internal intrigue, and not a single demand for ransom—at least not a real one. The thieves stole often but selectively, never taking more than a single painting at a time. These were not amateurs looking for quick scores or organized crime figures looking for a source of underworld cash. These were art thieves in the purest sense. One weary detective predicted that in all likelihood the paintings taken that long, hot summer would be missing for years, if not decades. In fact, he added morosely, chances were extremely good they would find their way into the Museum of the Missing and never be seen by the public again.

Even the police marveled at the variety of the thieves' game.
