The guard got off a few rounds before being mowed down by the snarling onslaught. Two creatures jumped on the Aussie's back, pushing him to the floor. Another creature lunged toward Trout, but stopped halfway and stared. In that brief instant, Trout could swear that he saw a glimpse of humanity in the thing's face. When he saw Trout wasn't wearing a uniform, he pounced instead on the Aussie.

Trout bolted for the door and bowled over the man who'd been guarding the prisoners. One of the creatures who'd followed Trout out the door saw the fallen guard and made short work of him.

Trout yelled at Gamay to drive the truck. He slid behind the steering wheel of the Mercedes and reached for the ignition key. Gone. He remembered that the Aussie had taken it with him. Gamay called out that the truck key was missing as well. Trout jumped out of the car, grabbed Gamay and told everyone to run for their lives.

From the sudden quietness from the Zoo, Trout guessed that the creatures were enjoying having the guards over for dinner. He didn't want to be around at dessert time.

AUSTIN AND Zavala were about a mile from the compound when they heard feet pounding along the road in the darkness ahead. They scuttled off the gravel road and threw themselves belly-down in the tall grass.

As the footfalls approached, they were intermingled with the low murmur of voices and a wheezing that suggested that some of the people coming toward them were not in the best of physical condition. Then he heard a familiar voice pleading. "Please move it along, folks. We'll have plenty of time to rest later."

Trout stopped short as two figures materialized from the darkness.

"You're a long way from Lost City," Austin said.

"Kurt and Joe?" Trout said with relief. "Damn. This is like old home week."

Gamay threw her arms around her NUMA colleagues.

"These are my friends, Mac and Sandy," Trout said. "I'll introduce the others later. Do you have a boat?"

Austin said, "I'm afraid we burned our bridges behind us. We saw a patrol boat out on the water earlier. Do you know where they keep it tied up?"

"I know where it might be." Trout cocked his ear and he frowned. "We've got to get out of here."

Austin had heard the noise, like the distant howling of the wind. "What's that?" He listened again. "Sounds like a pack of wolves chasing a deer." .

"I wish it were," Trout said. "Are you armed?"

"We've got handguns."

The howling was getting louder. Trout glanced back along the road again.

"Shoot anything that moves, especially if it's got red eyes," he said without further explanation. Austin and Zavala recalled the red-eyed furies from the video and didn't need any persuasion.

Trout took Gamay by the arm and called out to the others to get moving again. Austin and Zavala took up the rear.

The group walked in silence for fifteen minutes, urged on by the growing volume of the howling, until they could see the lights in the windows of the patrol boat barracks. Their pursuers were so close now that individual howls could be heard.

The noise must have penetrated the barracks walls because a couple of guards burst out of the building into the night as the fugitives were making their way around the blockhouse on their way to the dock.

The guards saw the faces reflected in the light coming from the door and yelled at the group to halt or be killed. One guard called into the building, and seconds later two more men emerged. One was half-dressed and the other, a big bearded man, must have been asleep because he was in his underwear. He grinned and said, "Looks like we caught ourselves a bonus from Strega."

His comrades roared with laughter, but their mirth was cut short, quickly turning to fear, as they heard the howling. The terrifying noise seemed to be coming from every direction. They huddled together, their guns facing outward, staring at the eyes that glowed like coals in the darkness.

The guard with the black beard sprayed the darkness with bullets. Cries of pain indicated that some bullets had hit a target. The gunfire triggered an onslaught. The creatures attacked from every direction, going after anyone wearing a uniform. The scientists and NUMA people took advantage of the bloody confusion and slipped away, with Trout showing the way to the dock where the patrol boat was tied up.

Austin got into the boat and started the engine. He climbed back onto the dock to help the others. MacLean was herding his fellow scientists into the boat. Then, as he was about to get in, shots rang out and he crumpled to the dock.

The shots had come from the bearded guard, who was running toward the boat. His slovenly lack of a uniform had protected him from being singled out by the creatures. Austin got off a quick shot that missed. The guard hadn't expected anyone to shoot back, but he quickly recovered, dropped to one knee and leveled his weapon.

A gunshot exploded in Austin's ear. Gamay had fired over his shoulder. She was an expert marksman, but in her haste her aim was off. The bullet caught the bearded man in the left shoulder. He screamed in rage and pain, but managed to swing his weapon around. Although he was deaf and dizzy from the shot near his ear, Austin stepped in front of his friends to shield them, raising his gun at the same time.

A chorus of howls came from behind the bearded guard. He turned and raised his gun, but he was buried under a pile of snarling creatures. Austin holstered his gun and he and Zavala were lifting MacLean into the boat when one of the creatures broke away from the others. It staggered toward the edge of the pier. Gamay raised her gun to shoot the creature. Trout, who was preparing to cast off the dock lines, stopped and grabbed her wrist. He recognized the creature as the one he had encountered in the blockhouse. "He's wounded," Trout said.

The creature's chest was dark with blood. He stared at Trout, and then his legs buckled and he pitched forward, dead, into the boat. Austin yelled at Trout to take the wheel while he tended to MacLean As soon as Gamay had cast off the lines, Trout gunned the throttle and pointed the bow into the darkness.

The boat sped from the island of horror at full throttle. Trout turned the wheel over to Gamay and went to MacLean who was lying on his back. The other scientists had made room for him. Austin had tucked a life jacket under MacLean's head as a pillow and he was kneeling beside the mortally wounded scientist. His ear was close to MacLean's mouth. He raised his head when he saw Trout and said, "He wants to talk to you."

Trout kneeled down on the other side of the dying scientist. "We got away, Mac," he said. "We'll get you to a doctor and get you fixed up in no time."

MacLean replied with a gurgling laugh and blood seeped out of the corner of his mouth. "Don't try to fool an old Scotsman, my friend."

When Trout went to reply, MacLean lifted a weak hand. "No.

Let me talk." His eyes started to roll back in his head, but he pulled himself together.

"The formula," he said.

"What about it?"

MacLean's eyes went to Austin's face. And then he died.

GERTRUDE CAME OUT to say good-bye. The AUV picked up the sound of the departing patrol boat and intercepted it about a mile from the island. Zavala saw the vehicle first. He was probing the darkness with a spotlight, looking for rocks, when the tall fin came into view. He thought it was a killer whale, but as it grew closer he saw rivets in the metallic fin and knew exactly what it was.

The vehicle paced them for a few hundred feet, then peeled off and went about its routine patrol. No one aboard the patrol boat knew how close they had come to disaster. Back at the command center, Max had sent the AUV to pursue the escaping boat and had armed all four of the torpedoes. He had set the launch switch and was about to hit the fire button when his throat had been ripped out by a red-eyed demon.
