“Gabriel will take Elizabeth Halton’s place as a hostage. The Sword of Allah and al-Qaeda will then make demands on the Israeli government instead of ours, and we’ll all be right back at square one.”

“With one important difference,” added Graham Seymour. “Much of the world will be rooting for the Sword to kill him. He is an Israeli and a Jew, an occupier and an oppressor, and therefore in the eyes of many in Europe and the Islamic world he is worthy of death. His murder would be a major propaganda victory for the terrorists.”

“But his cooperation will buy us something we have in exceedingly short supply at the moment,” said Eleanor McKenzie. “If we say yes tonight, we will be granted at least twenty-four additional hours to look for Miss Halton.”

“We’ve been looking for her for two weeks,” said Carter. “Unless someone has made some serious inroads that I’m not aware of, twenty-four additional hours aren’t going to make much of a difference.”

Gabriel looked at Robert Halton. It had been more than a week since Gabriel had seen him last, and in those days the ambassador’s face appeared to have aged many years. The prime minister would have been wise to conduct this conversation without Halton present, because to say no at this moment would be an act of almost unspeakable cruelty. Or perhaps that was exactly the reason the prime minister had invited him here. He had left Gabriel no option but to agree to the scheme.

“They’re going to make additional demands,” Gabriel said. “They’ll demand that I come alone. They’ll warn that if I’m followed, the deal is off and Elizabeth dies. We’re going to abide by those rules.” He looked at Seymour and Carter. “No surveillance, British or American.”

“You can’t go into this thing with no one watching your back,” said the chief of the Metropolitan Police.

“I don’t intend to,” said Gabriel. “MI5 and the Anti-Terrorist Branch of Scotland Yard will give us all the intelligence and support we require, but this will be an Israeli operation from start to finish. I will bring whomever and whatever I need into the country to conduct it. Afterward, there will be no scrutiny and no inquiries. If anyone is killed or wounded during the recovery of Elizabeth, no one from my team will be questioned or prosecuted.”

“Out of the question,” said Eleanor McKenzie.

“Done,” said the prime minister.

“How long will it take you to assemble the cash?”

“Every major bank in the City is already involved,” the prime minister said. “The task should be complete by late tomorrow afternoon. Obviously it’s a large consignment and therefore it will be somewhat unwieldy. They think it will fit into two large rolling duffel bags.”

Gabriel glanced from face to face. “Don’t even think about putting any tracking devices in the cash or the bags.”
