Precisely what was said between Gabriel Allon and Ambassador Robert Halton never became known and was not included in any record of the affair, overt or secret. Their conversation was brief, no more than a minute in duration, and the DS agent standing guard outside the ambassador’s office later described Gabriel as looking damp-eyed but determined as he emerged and made his way toward the ops center. This time the kidnappers did not make him wait. The call, according to the clock above John O’Donnell’s workstation, came at 20:00:14. Gabriel reached for it instantly, though he remembered thinking as he did so that he would be happy never to speak into a telephone again for as long as he lived. His greeting was calm and somewhat vague; his demeanor, as he listened to the instructions, was that of a traffic officer recording the details of a minor accident. He posed no questions, and his face registered no emotion other than profound irritation. At 20:00:57, he was heard to murmur: “I’ll be there.” Then he stood and pulled on his coat. This time Carter made no attempt to stop him as he started toward the stairs.

He paused for a moment in the ground-floor atrium to slip on his miniature earpiece and throat microphone, then nodded silently to the Marine guard as he exited the embassy grounds through the North Gate. Carter’s Vauxhall sedan was parked in a flagrantly illegal space on the corner of North Audley Street. The keys resided in Gabriel’s coat pocket, along with a GPS beacon the size of a five-pence coin. He opened the trunk and quickly inspected the cargo before adhering the beacon near the driver’s-side taillight. Then he climbed behind the wheel and started the engine. A moment later he was turning into Oxford Street and marveling at the crush of last minute shoppers. Carter’s watchers followed him as far as Albany Street, where they photographed him making a left turn and heading north. That would be their last contact with him. As far as the Americans and British were concerned, Gabriel had now disappeared from radar.

That was not the case, however, at the Israeli embassy in South Kensington, where, in one of the more bizarre coincidences of the entire affair, a group of well-meaning Christians had chosen that night to conduct a candlelight vigil calling for peace in the Holy Land. Inside the building, Ari Shamron and Uzi Navot were holding a vigil of their own. Their thoughts were not of peace or the holidays or even of home. They were huddled round a smoky table in the makeshift operations room, moving their forces into place, and watching a winking green light heading along the eastern fringe of Regent’s Park toward Hampstead.
