He parked where they told him to park, in the Constantine Road at the southern tip of Hampstead Heath. There was no other traffic moving in the street, and Gabriel, as he had made his final approach, detected no signs of surveillance, opposition or friendly. He shut off the engine and pressed the interior trunk release, then opened the center console hatch and dropped the keys inside. A gentle rain had started to fall. As he stepped outside, he cursed himself for failing to bring a hat.

He walked to the back of the car and removed the first duffel. As he was reaching for the second, he heard noises at his back and wheeled around to find a pack of young carolers advancing festively toward him. For a mad instant he wondered whether they might be the Sphinx’s watchers but quickly dismissed that notion as they bade him a Happy Christmas and paraded obliviously by. He placed the second bag in the street and closed the trunk. The carolers were now singing “O Come, All Ye Faithful” outside a small brick cottage strung with holiday lights. A sign in the window read: GIVE US PEACE IN OUR TIME.

Gabriel towed the duffel bags a few yards along the street, then crossed a footbridge over a set of sunken railroad tracks and entered the heath. To his right was a darkened running track. In the cement esplanade outside the padlocked gate, four immigrant men in their twenties were kicking a football about beneath the amber glow of a sodium lamp. They appeared to pay Gabriel no heed as he labored past and started up the slope of Parliament Hill, toward the bench where they had told him to wait for their next contact. He arrived to find it occupied by a small man with a frayed coat and matted beard. His accent, when he spoke to Gabriel, was East London and leaden with drink.

“Happy Christmas, mate. What can I do for you?”

“You can get off the bench.”

“It’s my bench tonight.”

“Not anymore,” said Gabriel. “Move.”

“Piss off.”

Gabriel drew Adrian Carter’s Browning Hi-Power and leveled it at the man’s head. “Get the fuck out of here and forget you ever saw me. Do you understand?”

“Loud and fucking clear.”

The man got quickly to his feet and melted into the darkness of the Heath. Gabriel ran his hand along the back and underside of the bench and found a mobile phone taped to the bottom of the seat on the left side. He quickly removed the battery and searched the phone for any concealed explosive charges. Then he reconnected the battery and pressed the POWER button. When the telephone was back online, he spoke quietly into his throat microphone.

“Nokia E50.”

“Number?” asked Uzi Navot.

Gabriel recited it.

“Any recent activity.”

“It’s clean.”

“Text activity?”

“Nothing.”
