In the case of Operation Masterpiece, those computers were tucked away in a redbrick Victorian house located at the end of a hushed cul-de-sac in the Highgate section of London. After working around the clock preparing for the operation in Paris, Gabriel and his team now worked around the clock sorting and analyzing the immense haul. In the blink of an eye, the life of one of the world’s most reclusive businessmen was now an open book. Indeed, as Uzi Navot would describe it to the prime minister during their weekly breakfast meeting, “Anywhere Martin goes, we go with him.”

They listened to his phone calls, they read his e-mail, they peered quietly over his shoulder while he surfed the Web. They negotiated deals with him, ate lunch with him, and went to cocktail receptions tucked in his breast pocket. They slept with him, bathed with him, exercised with him, and overheard a quarrel with Monique over his frequent trips to Paris. They accompanied him on a flying visit to Stockholm and were forced to endure an excruciating evening of Wagner with him. They knew his exact position on the planet at all times, and if he happened to be in motion, they knew the speed he was traveling. They also discovered that Saint Martin liked to spend a great deal of time alone sequestered in his office at Villa Elma, an expansive room located on the southeast corner of the mansion overlooking Lake Geneva, at precisely 1,238 feet above sea level.

There can be an obvious drawback to receiving such a vast amount of intelligence—the possibility that a vital piece of the puzzle might be swamped by a tsunami of useless information. Gabriel sought to avoid this pitfall by making certain that at least half the team remained focused on the true prize of the Paris operation, Martin’s laptop. The haul was not limited to the material contained on the computer the night of the operation in Paris. Indeed, through a clever feat of engineering, the computer automatically sent an update each time data was added or subtracted. It meant that whenever Martin opened a document, Gabriel’s team opened it, too. They even instructed the computer to transmit video from its built-in camera in thirty-minute loops. Most of the video was silent and black. But for an hour or so each day, whenever Martin was at task, he seemed to be peering directly into the Highgate safe house, watching Gabriel’s team as it rummaged through the secrets of his life.
