That sounded like a good lesson to remember, Andrea Price told herself, following her principal down the corridor. The code name, SURGEON, was perfect for her. Precise, smart, thorough. She might even have made a good agent except for her evident discomfort around guns.

It was already a regular routine, and in many ways that was not new. For a generation, the Japanese Air Self-Defense Force had responded to Russian fighter activity out of the forward base at Dolinsk Sokol—at first in cooperation with the USAF—and one of the regular tracks taken by the Soviet Air Force had earned the name "Tokyo Express," probably an unknowing reference to a term invented in 1942 by the United States Marines on Guadalcanal.

For security reasons the E-767's were based with the 6th Air Wing at Komatsu, near Tokyo, but the two F-15J's that operated under the control of the E-767 now aloft over the town of Nemuro at the northeast tip of the island of Hokkaido were actually based on the Home Island at Chitose. These were a hundred miles offshore, and each carried eight missiles, four each of heat-seekers and radar-homers. All were warshots now, requiring only a target.

It was after midnight, local time. The pilots were well rested and alert, comfortably strapped into their ejection seats, their sharp eyes scanning the darkness while fingers made delicate course-corrections on the sticks. Their own targeting radars were switched off, and though their aircraft still flashed with anticollision strobe lights, those were easily switched off should the necessity arise, making them visually nonexistent.

"Eagle One-Five," the digital radio told the element leader, "check out commercial traffic fifty kilometers zero-three-five your position, course two-one-five, angels three-six."

"Roger, Kami," the pilot replied on keying his radio. Kami, the call sign for the orbiting surveillance aircraft, was a word with many meanings, most of them supernatural like "soul" or "spirit." And so they had rapidly become the modern manifestation of the spirits guarding their country, with the F-15J's as the strong arms that gave power to the will of those spirits. On command, the two fighters came right, climbing on a shallow, fuel-efficient slope for five minutes until they were at thirty-seven thousand feet, cruising outbound from their country at five hundred knots, their radars still off, but now they received a digital feed from the Kami that appeared on their own sets, one more of the new innovations and something the Americans didn't have. The element leader alternated his eyes up and down. A pity, he thought, that the hand-off display didn't integrate with his head-up display. Maybe the next modification would do that.

"There," he said over his low-power radio.

"I have it," his wingman acknowledged.
