The Kill Artist

for the holidays.
    Tariq sat in a café on the opposite side of the canal, drinking warm sweet tea. He knew other things about David Morgenthau-things that did not appear in the society pages or the world's business journals. He knew that Morgenthau was a personal friend of the Israeli prime minister, that he had performed certain favors for Ari Shamron, and that he had once served as a secret conduit between the Israeli government and the PLO. For all those reasons, Tariq was going to kill him.
    Leila had prepared a detailed surveillance report during her stay in Amsterdam. David and Cynthia Morgenthau left the house each morning to visit museums or go ice-skating in the countryside. During the day the only person who remained in the house was a maid, a young Dutch girl.
    This is going to be too easy.
    A chauffeured Mercedes braked to a halt outside the house. Tariq looked at his watch: 4:00 P.M., right on schedule. A tall, gray-haired man climbed out. He wore a thick sweater and heavy corduroy trousers and was carrying two pairs of ice skates. A moment later an attractive woman emerged, dressed in black stretch leggings and a pullover. As they entered the house the Mercedes drove off.
    Tariq left a few guilders on the table and went out.
    Snow drifted over the Herengracht as he made his way slowly toward the houseboat on the Amstel. A pair of cyclists glided silently past, leaving ribbons of black in the fresh snow. Evening in a foreign city always made him melancholy. Lights coming on, offices letting out, bars and cafés slowly filling. Through the broad windows of the canal houses he could see parents coming home to children, husbands coming home to wives, lovers reuniting, warm lights burning. Life, he thought. Someone else's life, someone else's homeland.
    He thought about what Kemel had told him during their meeting on the train. Tariq's old nemesis, Gabriel Allon, had been brought back to help Ari Shamron find him. The news did not concern him. Indeed, he welcomed it. It would make the next few weeks even sweeter. Imagine, destroying their so-called peace process and settling his score with Gabriel Allon all at the same time…
    Killing Allon would not be easy, but as Tariq drifted along the banks of the Herengracht he knew he already held a distinct advantage over his opponent. The simple fact that he knew Allon was out there searching for him gave Tariq the upper hand. The hunter must come to the prey to make the kill. If Tariq played the game well, he could draw Allon into a trap. And then I'll kill him, the way he killed Mahmoud.
    Intelligence services have two basic ways of trying to catch a terrorist. They can use their superior technology to intercept the terrorist's communications, or they can penetrate his organization by inserting a spy or convincing an existing operative to switch sides. Tariq and Kemel were careful about the way they communicated. They avoided telephones and the Internet whenever possible and used couriers instead. Like the idiot Kemel sent to Samos! No, they would not be able to track him by intercepting his communications, so they would have to try to penetrate his group. It was difficult for an intelligence agency to penetrate any terrorist group, but it would be even harder to get inside Tariq's. His organization was small, tightly knit, and highly mobile. They were committed to the struggle, highly trained, and intensely loyal. None of his agents would ever betray him to the Jews.
    Tariq could use this to his advantage. He had instructed Kemel to contact every agent and give a simple instruction. If any of them noticed anything out of the ordinary-such as surveillance or an approach by a stranger-they were to report it immediately. If Tariq could determine that Israeli intelligence was involved, he would immediately be transformed from the hunted to the hunter.
    He thought of an operation he had conducted while he was still with Jihaz el-Razd, the PLO intelligence arm. He had identified an Office agent working with diplomatic cover from the Israeli embassy in Madrid. The officer had managed to recruit several spies within the PLO, and Tariq decided it was time to pay him back. He sent a Palestinian to Madrid posing as a defector. The Palestinian met with the Israeli officer inside the embassy and promised to turn over sensitive intelligence about PLO leaders and their personal habits. At first the Israeli balked. Tariq had anticipated this, so he had given his agent several
