The terrorists had not noticed him. Gabriel, still on one knee, leveled the Beretta in both hands and took aim at one of the black-suited men pulling the woman toward the van. It was thirty yards, a shot he had made countless times before. He squeezed his trigger twice in quick succession, tap-tap, just as he had been trained to do. An instant later there was a flash of pink and the man spiraled lifelessly to the ground, like a toy released by the hand of a child. Gabriel moved his aim a degree to the right and fired again. Another flash of blood and brain tissue. Another attacker gone.

This time there was answering fire. Gabriel rolled off the footpath and took cover behind the trunk of a tree as a hailstorm of gunfire tore the bark to shreds. When the firing stopped, he pivoted from behind the tree and saw that the terrorists had succeeded in getting the woman into the back of the van. One was closing the rear cargo door; the others were scurrying toward the second van. Gabriel took aim at the one closing the door and fired. The first shot hit the terrorist in the left shoulder blade, spinning him around. The second struck in the center of the chest.

The vans shot forward and started across the broad green, toward Marble Arch and the busy intersection at the northeast corner of the park. Gabriel rose to his feet and sprinted after them, then stopped and fired several shots into the back of the van that he knew contained only terrorists. The vans continued toward the perimeter of the park. Gabriel gave chase for a few more seconds; then, realizing he could not possibly close the gap, he turned and ran back to the site of the assault.

Nine bodies lay scattered over the blood-soaked footpath. The six Americans were all dead, as were the two terrorists that Gabriel had taken down with head shots. The one who a moment ago had been forcing the woman into the back of the van now lay gasping for breath, blood pouring from the mouth of his balaclava. Gabriel kicked the machine pistol from his grasp and tore the hood from his head. The face staring up at him was vaguely familiar. Then he realized it was Samir al-Masri, the Egyptian from west Amsterdam.

The Egyptian’s eyes were beginning to lose focus. Gabriel wanted something from him before he died. He lifted the Egyptian by the front of his jumpsuit and slapped him hard across the face.

“Where are they taking her, Samir? Tell me what you’re going to do with the girl!”

The eyes focused for a moment.

“How do you know my name?”

“I know everything, Samir. Where are they taking the girl?”

He managed a mocking smile. “If you know everything, then why are you asking me?”
