THE SENATE SELECT COMMITTEE convened one month after the attempt on the president’s life. In their opening statements the ranking members assured the American people that their investigation would be thorough and unsparing, but by the end of the first week senators from both parties were openly frustrated by what they came to regard as a lack of candor by the president’s security and intelligence chiefs. The president’s men explained in painstaking detail how the forces of global Islamic extremism had managed to penetrate the center of Christendom, and how Professor Ali Massoudi had managed to recruit a young Swiss named Erich Müller and insert him into the Pontifical Swiss Guard. But when it came to who had masterminded the two attacks on the Vatican—and more important, who had footed the bill—the president’s men could offer up only informed opinion. Nor could they explain to any of the committee members’ satisfaction the presence at the Vatican of one Gabriel Allon, the now-legendary Israeli agent and assassin. After much internal deliberation, the senators decided to subpoena him for themselves. Because he was a foreign national he was under no obligation to obey the summons and, as expected, he steadfastly refused to appear. Three days later he abruptly changed his mind. He would testify, he told them, but only in secret. The senators agreed, and asked him to come to Washington the following Thursday.

HE ENTERED the subterranean hearing room alone. When the committee chairman asked him to stand and state his name for the record, he did so without hesitation.

“And your employer?”

“The prime minister of the State of Israel.”

“We have many questions we would like to ask you, Mr. Allon, but we have been told by your ambassador that you will not answer any question that you deem inappropriate.”

“That’s correct, Mr. Chairman.”

“We have also been informed that you wish to read a statement into the record before we begin the questioning.”

“That is also correct, Mr. Chairman.”

“This statement deals with the country of Saudi Arabia and America’s relationship to it.”

“Yes, Mr. Chairman.”

“Just a reminder, Mr. Allon. While this testimony is being taken in secret, there will still be a transcript made of your remarks.”

“I understand, sir.”

“Very well. You may proceed.”

With that he looked down and began to read his statement. In the far corner of the room, one man visibly winced. Hercules has come to the United States Senate, the man thought. And he’s brought a quiver full of arrows dipped in gall.

“CONGRATULATIONS, GABRIEL,” said Adrian Carter. “You just couldn’t help yourself, could you? We gave you the stage, and you put it to good use.”

“The senators needed to know about the true nature of the Saudi regime and its support for global terrorism. The American people need to know how all those petrodollars are being spent.”

“At least you kept Zizi’s name out of it.”
