Shortly after one a.m., the lights were extinguished, signaling the official conclusion of Martin’s annual gala. Within minutes, Gabriel heard the beating of rotors and saw the running lights of a helicopter descending slowly toward Martin’s lawn. It remained there scarcely more than a minute, then rose once again and turned eastward over the lake. Lavon joined Gabriel at the window and watched the helicopter disappear into the darkness.

“Do you suppose Mikhail and Zoe are on that bird?”

“They could be,” Gabriel conceded. “But if I had to guess, I’d say that’s Martin and Monique.”

“Where do you think they’re going?”

“At this hour…I can think of only one place.”

AS IT turned out, it took just fifteen minutes for Graham Seymour to get the two Office computer technicians from the safe house in Highgate to Grosvenor Square. They were quickly joined by four cybersleuths from MI5, along with a team of Iran analysts from the CIA and MI6. Indeed, by midnight London time, more than a dozen officers from four intelligence services were huddled around the computer in the fishbowl, watched over intently by Chiara. As for the four most senior members of Operation Masterpiece, they remained at their posts, staring glumly at the messages streaming across the status boards.

“Looks as if our boy has decided to flee the scene of the crime,” Seymour said, face buried in his hands. “Do you think there’s any way Mikhail and Zoe are still inside that mansion?”

“I suppose there’s always a chance,” said Adrian Carter, “but Martin doesn’t strike me as the sort to leave a mess lying around. Which means the clock is now definitely ticking.”

“That’s true,” said Shamron. “But we have several things working in our favor.”

“Really?” asked Seymour incredulously, gesturing toward the status boards. “Because from where I sit, it looks as though Zoe and Mikhail are about to disappear without a trace.”

“No one’s going to disappear.” Shamron paused, then added gloomily, “At least, not right away.” He laboriously lit a cigarette. “Martin isn’t stupid, Graham. He’ll want to know exactly who Mikhail and Zoe are working for. And he’ll want to know how much damage has been done. Getting information like that takes time, especially when a man like Mikhail Abramov is involved. Mikhail will make them work for it. That’s what he’s trained to do.”

“And what if they decide to take a shortcut?” asked Seymour. “How long do you expect Zoe to be able to hold up?”

“I’m afraid I have to side with Graham,” said Carter. “The only way we’re going to get them back is to make a deal.”

“With whom?” asked Navot.

“At this point, our options are rather limited. Either we call Swiss security or we deal directly with Martin.”
