Well east of the last of the barracks on the South Korean side of the DMZ was scrubland spotted with low-lying hills and occasional thickets. The military held maneuvers beyond the hills; though difficult to see from the north, the sounds of tanks and artillery fire, especially during nighttime activity, could be alarming.

One of the thickets, nearly twenty yards across, grew over a rocky depression nearly a half mile from the DMZ. It was a mined area that Captain Ohn Bock personally checked at least twice a day. There, just seven weeks before, ROK forces had quietly built a tunnel four feet in diameter: unknown to the North Koreans, it allowed the South to keep an eye on activity in the network of tunnels that the enemy had excavated under the DMZ. The South Korean tunnel didn't actually connect with the North Korean tunnel; audio devices and motion detectors had been poked through the tunnel walls to keep track of spies being smuggled into the South from an exit hidden beneath rock and shrubs a quarter mile farther south. These operatives were then followed, their identities reported to both Military Intelligence and the KCIA.

As planned, Captain Bock had arranged his evening trip to the tunnel to coincide with the arrival of his childhood friend Major Kim Lee. The Captain and an aide drove up shortly after Lee arrived. They were already unloading the chemical drums. Bock saluted his superior.

"I was happy to get your call," Bock said. "This has been a great day for you."

"It's not yet over."

"I've heard bodies were discovered on the ferry and that the seaplane pilot returned on time. Colonel Sun's operation, too, appears to be going as planned."

In the two years that he'd known him, and in the year that this operation had been in the planning stage, Bock had never once seen the stoic Major show any emotion. But that was especially true now. Whereas another man might be expected to show relief at what had been accomplished, or anticipation over what was still to come-- Bock himself was more anxious as the hour grew closer-- Lee seemed almost supernaturally calm. His sonorous voice was soft, his movements unhurried, his manner slightly more reserved than normal. And he was the man going into the hole, not Bock.

"You've taken care of the tunnel watch for tonight?"

"Yes, sir. My man Koh is on the monitors. He's my computer genius. He'll make sure the surveillance equipment registers nothing until you've returned."

"Excellent. We're still planning to move at 0800 hours."

"I'll be waiting here for you."

With a smart salute, the Captain turned, climbed into his jeep, and returned to his post and to his job reviewing reports from along the DMZ and shuffling them off to Seoul. If all went well, after tonight he would be reviewing troops and not papers as they prepared to fend off an attack from the North.
