'They just acquired us on radar," the Iranian interjected, as a high-pitched alert sounded from the instrument panel and a line of green warning diodes turned red.

"Right on schedule." Ramirez nodded. "The U.S. Navy never sleeps." He turned and motioned to one of the men crouched on a litter in the main cabin, shouting above the noise. "Peretz, it's time to start earning your share."

Dore Peretz, a veteran of the Weizman Institute, was a specialist in strategic weapons and their delivery. But that was another life. Now he was free-lance. Ramirez had picked him for his technical skills, and his greed.

He rose and made his way forward, working carefully through the jumble of legs and automatic weapons. He was younger than he appeared; his prematurely salt-and-pepper hair made him look late forties, though he actually was only thirty-nine. He settled into the weapons station below Salim, pulling down his black turtleneck, the better to accommodate a flight helmet, and went to work.

"Are you ready?" he asked Salim, in perfect Farsi.

"I am ready if God is ready," the Iranian replied grimly, his eyes beginning to gleam from the strain.

Peretz reached down and switched the radio to 121.50 megahertz, the military emergency channel.

"Mayday. Mayday. Israeli Hawk One requesting permission for emergency approach." He then repeated the announcement in Hebrew. It was, of course, a pointless gesture for the illiterate Americans, but for now verisimilitude counted.

"We copy you, Hawk One. This is USS Glover. We've acquired you on radar," came back the response, a Southern drawl, young and slightly nervous. "What seems to be the problem?"

"One of our turboshafts has started losing oil pressure. We could use a visual check. What's your position?" He glanced down at the green radar screen and grinned. It showed the frigate's coordinates to within meters.
