Deep Six

though operating intermittently, was operating. And any assault from the river side was ruled out because the absence of visibility made it next to impossible to home in on the yacht. The fog, it seemed, was a blessing in disguise.

Blackowl glanced up at the clock. It read one minute before the post change. He quickly reread the security plan that listed the names of the agents, the areas they were scheduled to patrol and the times. He noted that agent Lyle Brock was due to stand post number seven, the yacht itself, while agent Karl Polaski was slated for post number six, which was the pier.

He pressed the transmit button and spoke into the tiny microphone attached to his headset. “Attention all stations. Time zero two hundred hours. Move to your next post. Repeat, move to the next post on your schedule.” Then he changed frequencies and uttered the code name of the shift leader. “Cutty Sark, this is Control.”

A veteran of fifteen years in the service, agent Ed McGrath answered almost immediately. “Cutty Sark here.”

“Tell posts numbers six and seven to keep a sharp watch on the river.”

“They won’t see much in this slop.”

“How bad is it around the dock area?”

“Let’s just say you should have issued us white canes with red tips.”

“Do the best you can,” Blackowl said.

A light blinked and Blackowl cut transmission to McGrath and answered the incoming call.

“Control.”

“This is River Watch, Control. Whoever is screwing up our radar signals seems to be transmitting continuously now.”

“You read nothing?” asked Blackowl.

“The geographic display on the oscilloscope is forty percent blanked out. Instead of blips we receive a large wedge shape.”

“Okay, River Watch, let me pass the word to the special agent in charge. Maybe he can track the interference and stop any further transmission.”

Before he apprised Oscar Lucas at the White House of the radar problem, Blackowl turned and gazed curiously at the television monitors. They reflected no discernible image, only vague shadows wavering in wraithlike undulation.

Agent Karl Polaski refixed the molded earplug of his Motorola HT-220 radio receiver and wiped the dampness from his Bismarck mustache. Forty minutes into his watch on the pier, he felt damp and downright miserable. He wiped the moisture from his face and thought it odd that it felt oily.

His eyes wandered to the overhead floodlights. They gave out a dim yellowish halo, but the edges had a prismatic effect and displayed the colors of the rainbow. From where he stood, about midpoint on the thirty-foot dock, the Eagle was completely hidden by the oppressive mist. Not even her deck or mast lights were visible.

Polaski walked over the weatherworn boards, occasionally stopping and listening. But all he heard was the gentle lapping of the water around the pilings and the soft hum of the yacht’s generators. He was only a few steps from the end of the pier when the Eagle finally materialized from the gray tentacles of the fog.

He called softly to agent Lyle Brock, who was manning post seven on board the boat. “Hey, Lyle. Can you hear me?”

A voice replied slightly above a whisper. “What do you want?”

“How about a cup of coffee from the galley?”

“The next post change is in twenty minutes. You can get a cup when you come on board and take my place.”

“I can’t wait twenty minutes,” Polaski protested mildly. “I’m already soaked to the bones.”

“Tough. You’ll have to suffer.”

Polaski knew that Brock couldn’t leave the deck under any circumstances, but he goaded the other agent good-naturedly. “Wait till you want a favor from me.”

“Speaking of favors, I forgot where I go from here.”

Polaski gave a quizzical look at the figure in the shadows on the Eagle’s deck. “Look at your diagram, numb brain.”

“It got soggy and I can’t read it.”

“Post eight is fifty yards down the bank.”

“Thanks.”

“If you want to know where post nine is it’ll cost you a cup of coffee,” Polaski said, grinning.

“Screw you. I remember that one.”

Later, during the next post change, the agents merely waved as they passed each other, two indistinct forms in the mist.

Ed McGrath could not recall having seen fog this thick. He sniffed the air, trying to identify the strange aroma that hung everywhere, and finally wrote it off as a common oily smell. Somewhere in the mist he heard a dog bark. He paused, cocking one ear. It was not the baying of a hound in chase or the frightened yelps of a mutt, but the sharp yap of a dog alert to an unfamiliar presence. Not too far away, judging by the volume. Seventy-five, maybe a hundred, yards beyond the security perimeter, McGrath estimated.

A potential assassin would have to be sick or brain damaged or both, he thought, to stumble blindly around a strange countryside in weather such as this. Already, McGrath had tripped and fallen down, walked into an unseen tree branch and scratched his cheek, found himself lost three times, and almost got himself shot when he accidentally walked onto a guard post before he could radio his approach.

The barking stopped abruptly, and McGrath figured a cat or some wild animal had set the dog off. He reached a familiar bench beside a fork in a graveled path and made his way toward the riverbank below the yacht. He spoke into his lapel microphone.

“Post eight, coming up on you.”

There was no reply.

McGrath stopped in his tracks. “Brock, this is McGrath, coming up on you.”

Still nothing.

“Brock, do you read me?”

Post number eight was oddly quiet and McGrath began to feel uneasy. Moving very slowly, one step at a time, he cautiously closed on the guard area. He called faintly through the mist, his voice weirdly magnified by the heavy dampness. Silence was his only reply.

“Control, this is Cutty Sark.”

“Go ahead, Cutty Sark,” came back Blackowl’s tired voice.

“We’re missing a man on post eight.”

Blackowl’s tone sharpened considerably. “No sign of him?”

“None.”

“Check the boat,” Blackowl said without hesitation. “I’ll meet you there after I inform headquarters.”

McGrath signed off and hurried along the bank to the dock. “Post six, coming up on you.”

“Aiken, post six. Come ahead.”

McGrath groped his way onto the dock and found agent John Aiken’s hulking figure under a floodlight. “Have you seen Brock?”

“You kidding?” answered Aiken. “I haven’t seen shit since the fog hit.”

McGrath dogtrotted along the dock, repeating the call-warning process. By the time he reached the Eagle, Polaski had come around from the opposite deck to meet him.

“I’m missing Brock,” he said tersely.

Polaski shrugged. “Last I saw of him was about a half-hour ago when we changed posts.”

“Okay, stand here by the dockside. I’m going to take a look below decks. And keep an eye peeled for Blackowl. He’s on his way down from Control.”
