Harwich, ancient port of fifteen thousand souls at the confluence of the rivers Stour and Orwell, lay darkened and slumbering beneath a steady onslaught of rain. The waters of Ramsey Creek were empty of commercial craft, and only a handful of cars had gathered at the ferry terminal for the morning’s first passage to the Continent. The medieval town center was tightly shuttered and abandoned to the gulls.

It was into this setting that six field operatives from the foreign intelligence service of the State of Israel arrived at precisely 4:45 A.M. on Christmas morning. By five o’clock they had confirmed that the warehouse in West Dock Road was indeed occupied, and by 5:15 they had managed to place a small wireless camera in the corner of a broken window at the back. They were now carefully dispersed among the surrounding streets. Yaakov had taken up a post hundred yards from the warehouse in the Station Road. Yossi was encamped in the Refinery Road. Oded and Mordecai had hastily concealed the surveillance van beneath an overpass of the A120. Mikhail and Chiara, who had spent that night atop the BMW bike, were sheltering in the back of the van, staring at the screen of the video receiver. The image there was poorly framed and prone to static. Even so, they could see clearly what was taking place inside the warehouse. Four men dressed in black were loading large drums of liquid into the back of a Vauxhall panel van, under the supervision of a slender Egyptian-looking man in a burgundy V-necked sweater.

At 5:40, the five men slipped out of camera range. Then, ten minutes later, they returned with the final component of their weapon of mass murder—a man in a blue-and-white tracksuit, bound and trussed in packing tape, his face bloodied and swollen.

“Please tell me he’s alive, Mikhail.”

“He’s alive, Chiara.”

“How can you tell?”

“They wouldn’t be putting him in with the bomb if he was dead.”

But the best evidence he was alive, Mikhail thought darkly, was his head. If Gabriel were dead, it wouldn’t still be attached to his shoulders. He didn’t share this observation with Chiara. She’d been through enough that night already.

At 5:55, the four men in black stripped down to their street clothes. Three climbed into a Mercedes cargo truck and departed. The fourth climbed behind the wheel of the Vauxhall panel van, while the Egyptian-looking man with the burgundy sweater joined Gabriel in the back. At precisely six A.M., the van turned into West Dock Street and made its way toward the entrance of the A120. Four vehicles followed carefully after it. Yaakov took the first shift at the point, while Chiara and Mikhail brought up the rear on the BMW bike. Mikhail sat on the back. The gunner’s seat.
