"I think so," someone said to her, and then Ellie turned the radio down. Then they smelled the odor, a garbage stench of putrefaction and decay that drifted up the hillside toward them.

Grant whispered, "He's here."

"She," Malcolm said.

The goat was tethered in the center of the field, thirty yards from the nearest trees. The dinosaur must be somewhere among the trees, but for a moment Grant could see nothing at all. Then he realized he was looking too low: the animal's head stood twenty feet above the ground, half concealed among the upper branches of the palm trees.

Malcolm whispered, "Oh, my God… She's as large as a bloody building…"

Grant stared at the enormous square head, five feet long, mottled reddish brown, with huge jaws and fangs. The tyrannosaur's jaws worked once, opening and closing. But the huge animal did not emerge from hiding.

Malcolm whispered: "How long will it wait?"

"Maybe three or four minutes. Maybe-"

The tyrannosaur sprang silently forward, fully revealing her enormous body. In four bounding steps she covered the distance to the goat, bent down, and bit it through the neck. The bleating stopped. There was silence.

Poised over her kill, the tyrannosaur became suddenly hesitant. Her massive head turned on the muscular neck, looking in all directions. She stared fixedly at the Land Cruiser, high above on the hill.

Malcolm whispered, "Can she see us?"

"Oh yes," Regis said, on the intercom. "Let's see if she's going to eat here in front of us, or if she's going to drag the prey away."

The tyrannosaur bent down, and sniffed the carcass of the goat. A bird chirped: her head snapped up, alert, watchful. She looked back and forth, scanning in small jerking shifts.

"Like a bird," Ellie said.

Still the tyrannosaur hesitated. "What is she afraid of?" Malcolm whispered.

"Probably another tyrannosaur," Grant whispered. Big carnivores like lions and tigers often became cautious after a kill, behaving as if suddenly exposed. Nineteenth-century zoologists imagined the animals felt guilty for what they had done. But contemporary scientists documented the effort behind a kill-hours of patient stalking before the final lunge-as well as the frequency of failure. The idea of "nature, red in tooth and claw" was wrong; most often the prey got away. When a carnivore finally brought down an animal, it was watchful for another predator, who might attack it and steal its prize. Thus this tyrannosaur was probably fearful of another tyrannosaur.

The huge animal bent over the goat again. One great hind limb held the carcass in place as the jaws began to tear the flesh.

"She's going to stay," Regis whispered. "Excellent." The tyrannosaur lifted her head again, ragged chunks of bleeding flesh in her jaws. She stared at the Land Cruiser. She began to chew. They heard the sickening crunch of bones.

"Ewww," Lex said, over the intercom. "That's disgusting."

And then, as if caution had finally gotten the better of her, the tyrannosaur lifted the remains of the goat in her jaws and carried it silently back among the trees.

"Ladies and gentlemen, Tyrannosaurus rex, " the tape said. The Land Cruisers started up, and moved silently off, through the foliage.

Malcolm sat back in his seat. "Fantastic," he said.

Gennaro wiped his forehead. He looked pale.

Henry Wu came into the control room to find everyone sitting in the dark, listening to the voices on the radio.

"-Jesus, if an animal like that gets out," Gennaro was saying, his voice tinny on the speaker, "there'd be no stopping it."

"No stopping it, no…"

"Huge, with no natural enemies…"

"My God, think of it…"

In the control room, Hammond said, "Damn those people. They are so negative."

Wu said, "They're still going on about an animal escaping? I don't understand. They must have seen by now that we have everything under control. We've engineered the animals and engineered the resort…" He shrugged.

It was Wu's deepest perception that the park was fundamentally sound, as he believed his paleo-DNA was fundamentally sound. Whatever problems might arise in the DNA were essentially point-problems in the code, causing a specific problem in the phenotype: an enzyme that didn't switch on, or a protein that didn't fold. Whatever the difficulty, it was always solved with a relatively minor adjustment in the next version.

Similarly, he knew that Jurassic Park's problems were not fundamental problems. They were not control problems. Nothing as basic, or as serious, as the possibility of an animal escaping. Wu found it offensive to think that anyone would believe him capable of contributing to a system where such a thing could happen.

"It's that Malcolm," Hammond said darkly. "He's behind it all. He was against us from the start, you know. He's got his theory that complex systems can't be controlled and nature can't be imitated. I don't know what his problem is. Hell, we're just making a zoo here. World's full of 'em, and they all work fine. But he's going to prove his theory or die trying. I just hope he doesn't panic Gennaro into trying to shut the park down."

Wu said, "Can he do that?"

"No," Hammond said. "But he can try. He can try and frighten the Japanese investors, and get them to withdraw funds. Or he can make a stink with the San Jose government. He can make trouble."

Arnold stubbed out his cigarette. "Let's wait and see what happens," he said. "We believe in the park. Let's see how it plays out."

Muldoon got off the elevator, nodded to the ground-floor guard, and went downstairs to the basement. He flicked on the lights. The basement was filled with two dozen Land Cruisers, arranged in neat rows. These were the electric cars that would eventually form an endless loop, touring the park, returning to the visitor center.

In the corner was a Jeep with a red stripe, one of two gasoline-powered vebicles-Harding, the vet, had taken the other that morning-which could go anywhere in the park, even among the animals. The Jeeps were painted with a diagonal red stripe because for some reason it discouraged the triceratops from charging the car.

Muldoon moved past the Jeep, toward the back. The steel door to the armaments room was unmarked. He unlocked it with his key, and swung the heavy door wide. Gun racks lined the interior. He pulled out a Randler Shoulder Launcher and a case of canisters. He tucked two gray rockets under his other arm.

After locking the door behind him, he put the gun into the back seat of the Jeep. As he left the garage, he heard the distant rumble of thunder.

"Looks like rain," Ed Regis said, glancing up at the sky.

The Land Cruisers had stopped again, near the sauropod swamp. A large herd of apatosaurs was grazing at the edge of the lagoon, eating the leaves of the upper branches of the palm trees. In the same area were several duckbilled hadrosaurs, which in comparison looked much smaller.

Of course, Tim knew the hadrosaurs weren't really small. It was only that the apatosaurs were so much larger. Their tiny heads reached fifty feet into the air, extending out on their long necks.

"The big animals you see are commonly called Brontosaurus, " the recording said, "but they are actually Apatosaurus. They weigh more than thirty tons. That means a single animal is as big as a whole herd of modern elephants. And you may notice that their preferred area, alongside the lagoon, is not swampy. Despite what the books say, brontosaurs avoid swamps. They prefer dry land."

"Brontosaurus is the biggest dinosaur, Lex," Ed Regis said. Tim didn't bother to contradict him. Actually, Brachiosaurus was three times as large. And some people thought Ultrasaurus and Seismosaurus were even larger than Brachiosaurus. Seismosaurus might have weighed a hundred tons!

Alongside the apatosaurs, the smaller hadrosaurs stood on their hind legs to get at foliage. They moved gracefully for such large creatures. Several infant hadrosaurs scampered around the adults, eating the leaves that dropped from the mouths of the larger animals.

"The dinosaurs of Jurassic Park don't breed," the recording said. "The young animals you see were introduced a few months ago, already hatched. But the adults nurture them anyway."

There was the rolling growl of thunder. The sky was darker, lower, and menacing.

"Yeah, looks like rain, all right," Ed Regis said.

The car started forward, and Tim looked back at the hadrosaurs. Suddenly, off to one side, he saw a pale yellow animal moving quickly. There were brownish stripes on its back. He recognized it instantly. "Hey!" he shouted. "Stop the car!"

:'What is it?" Ed Regis said.

'Quick! Stop the car!"

"We move on now to see the last of our great prehistoric animals, the stegosaurs," the recorded voice said.

"What's the matter, Tim?"

"I saw one! I saw one in the field out there!"

"Saw what?"

"A raptor! In that field!"

"The stegosaurs are a mid-Jurassic animal, evolving about a hundred and seventy million years ago," the recording said. "Several of these remarkable herbivores live here at Jurassic Park-"

"Oh, I don't think so, Tim," Ed Regis said. "Not a raptor."

"I did! Stop the car!"

There was a babble on the intercom, as the news was relayed to Grant and Malcolm. "Tim says he saw a raptor."

"Where?"

"Back at the field."

"Let's go back and look."

"We can't go back," Ed Regis said. "We can only go forward. The cars are programmed."

"We can't go back?" Grant said.

"No," Regis said. "Sorry, You see, it's kind of a ride-"

"Tim, this is Professor Malcolm," said a voice cutting in on the intercom. "I have just one question for you about this raptor. How old would you say it was?"

"Older than the baby we saw today," Tim said. "And younger than the big adults in the pen. The adults were six feet tall. This one was about half that size."

"That's fine," Malcolm said.

"I only saw it for a second," Tim said.

"I'm sure it wasn't a raptor," Ed Regis said. "It couldn't possibly be a raptor. Must have been one of the othys. They're always jumping their fences. We have a hell of a time with them."
