She had no trouble slipping into the Van Dyke with a group of people going to the top-floor restaurant. When they got off at the top floor, Julie got out with them, but instead of entering the restaurant, she ducked into the short flight of service stairs that led to the roof. From there she had a fine view of upper Manhattan, with the dark mass of Central Park directly in front of her and traffic crawling by a long way below on the street. A cutting wind blew her hair around, and she slipped on a knit cap to hold it in place. “Here we go!” she said aloud.

She fixed her ropes and swung over to the roof of the Plaza. From there she tied her rope to a cornice and, taking a deep breath, swung out again into space, bracing herself with one foot so as not to spin. The stars and the street seemed equally distant as she lowered herself to the level of the apartment windows.

They were open, saving her from having to cut through them with a vibrator tool.

She swung in through the billowing white curtains, landed soundlessly inside the darkened apartment, and rolled to her feet. She could see pretty well with the infrared-enhanced goggles she now snapped on. Her feet were set in a defensive pose, but there was no one there. She gave the rope a snap and it came free from the cornice. She wound it around her waist. Now there was no evidence of her means of entry.

She looked around the apartment. It was large, with a drawing room and a separate bedroom. She checked out the kitchen. The refrigerator was filled with a very good brand of champagne, and there were tins of caviar in the pantry. This Khalil seemed to live on the rarest of fare. The question now was where did he keep the jewelry?

She knew that Gibberman had chosen this mark carefully. Ahmed Khalil was renowned as an international playboy. He loved to give expensive gifts to his ladies of the evening. But where did he keep the trinkets?

She had already learned from inside sources that he didn't entrust them to hotel safes. He wanted them close at hand for the moment when he chose to reward his current lady.

She moved quickly around the apartment Although the place was big, it was still only a hotel suite. The stuff has to be here somewhere….

And then, suddenly, the lights came on.

“Good evening, my dear,” a deep, resonant voice said.

Julie saw a tall, very thin, dark-faced man leaning negligently against the wall. He was wearing a checked headdress. He had a short beard and luxuriant mustache. His face was narrow, and he had a hawk's nose with a large mole in the left corner. Standing beside him was another man, also an Arab, but large — in fact, huge — with a full head of fuzzy black hair and so much facial hair that his features were all but obscured. Julie, however, had no trouble seeing the knife he held in his right hand.

“What are you doing here?” Julie asked. “You're supposed to be seeing an opera.”

Khalil, the tall thin man, smiled. “Your information is reliable, but so was my counterintelligence service. We always keep an eye on Gibberman when we come to New York. He's stung us before. We knew when you visited him to set up the job. Didn't we, Sfat?”

The giant smiled and touched the point of his dagger with the ball of his thumb.

Khalil said, “Gibberman was happy to tell us what he had set up for this evening.”

Julie nodded. Talk about luck.

“You mustn't hold it against Gibberman for talking,” Khalil said. “When Sfat takes the knife to somebody, secrets are shouted from the rooftops. His skill is better than a surgeon's. With that knife he can lay bare a single nerve, in the arm, for example, and play on it as if it were the string on a violin. It is an unforgettable experience, my dear, and one I'm sure you wouldn't want to miss.”

Julie thought of how she had told Stan that nothing ever went wrong. What a laugh! Of course, it was all bad luck. How could she have guessed that Khalil would find out about Gibberman? She had discounted the efficiency of the counterintelligence corps these rich Arabs employed.

“Well, Khalil,” Julie said, “looks like I'm foiled and caught in the act. Have your man step away from the door and I'll leave quietly.”

Khalil smiled. “I'm afraid it's not going to be so easy, my dear.”

“You're going to turn me over to the police?”

“Eventually. If there's enough left of you. First, however, it will be necessary to teach you a lesson. Sfat!”

The big man took a slow step toward her.

Julie said, “I thought it would be like that. Thanks, Khalil.”

“For what?”

“For freeing me of any scruples. If I ever had any, you've put them completely out of my mind.”

She turned to face Sfat, and took two steps toward him while Khalil folded his arms and waited for the fun to begin, a small smile on his lips.

Sfat lifted his arms, hands formed into blades. He bent his knees, feet pointed outward, and Julie recognized the typical fighting stance of a Saudi karate fighter. It was a technique that had its limitations. Sfat advanced, mincingly for so large a man, and his bearded face was set in a mask of cruelty. As he came within range his left hand darted out, the finger's shaped like a hawk's head.

She was ready for it, had been anticipating it. She ducked under the swooping blow and, with a short, economical kick, connected with Sfat's left kneecap. He had been turning as she kicked, and some of the force of the blow was lost. Nevertheless, it was enough to take his feet out from under him. He fell heavily, and Julie pounced.

But this time he caught her unawares. Sfat's clumsy fall had been feigned, and as she came leaping at him his arms and legs were drawn up cat fashion, and he lashed out, expecting to catch her in the solar plexus. She had seen her danger a moment before his counterstroke, however, and turning in midair, managed to avoid his flailing limbs. Her stiffened elbow caught him in the pit of the stomach, knocking the air out of him, and in the second it took him to recover, she rolled away and regained her feet.

Khalil had been watching all this dumbfounded. Now, belatedly, he stirred into action. He stepped forward, crouching in a classic knife fighter's pose. The weapon he carried in his right hand and low against his body was a yata, a traditional Yemeni dagger, about eight inches long, slightly curved, and sharpened to a razor edge. It was made from a Swedish saw blade, and fitted with an elaborate rhino-horn handle. Arabic letters were engraved on the blade. Julie's eyes widened when she saw the weapon.

“You do well to fear the yata” Khalil said, advancing, light twinkling off the point like the gaze of a one-eyed basilisk.

“Oh, I wasn't exactly afraid of it,” Julie said. “Just surprised to see it. Rhino horn is not legally traded. Is it genuine?”

“Of course,” Khalil said, feinting and then making a lightning stab at her. “I always kill with the genuine article.”

“I'm sure glad to hear that,” Julie said. That makes that knife extremely valuable!”

The blade darted toward her midsection. Julie spun, and the thing passed harmlessly along her left side. As it passed, her arm snapped down, trapping the weapon. Khalil began a long and elaborate Arabic curse in the guttural dialect of Omdurman, but got out no more than a couple of syllables before Julie's left elbow crashed with piledriver force into the middle of his face.

Blood streaming from his nose and mouth, Khalil stumbled backward, losing his grip on the knife that was still clamped under Julie's left arm.

“I'll just keep this for you,” Julie said, slipping the knife into her belt. “It might reduce its value if we got blood all over it.”

A feint to the midsection drew down Khalil's guard. Fingers folded in protectively, Julie snapped a blow. The heel of her hand caught Khalil where the upper lip meets the nose. Four of his front teeth cracked off clean at the gum line.
