Lycon skidded to a stop on the muddy field. He did not need to glance behind him to know he was alone with the beast. Its eyes glowed in the sunset as it turned from the butchered dogs and stared at its pursuer.

Lycon advanced his spear, making no attempt to throw it. As fast as the sauropithecus moved, it would easily dodge his cast. And Lycon knew that if the beast leaped, he was dead-dead as Pentheus after his sisters rent him in their fury. His only chance was that he might drive his spear home, might take his slayer with him-and he thought the beast recognized that.

It crouched like a wrestler advancing upon a foe, its lips drawn in a savage grin-and then it vaulted back over the hedge again.

Lycon tried to make his dry mouth shape a prayer of thanks. Eyes intent on the hedge, he held his spear at ready. Then he heard feet splatting at a clumsy run behind him.

Galerius puffed toward him, accompanied by several of the archers in a straggling clot. "That hut back there caught fire!" he blurted. "Didn't you see it? Just a ball of flame by the time we could get to it. Don't know if anyone was there, or if they got out or…"

He caught sight of the torn bodies of the hounds, and his puffing excitement trailed off. His voice drawled in wonder: "What happened here?"

Lycon finally let his breath out. "Well, I found the lizard-ape we were supposed to be hunting-while you fools were back there gawking at your fire! Now I think Vonones owes you for a pack of dogs."

Lycon waited long enough to make certain the lizard-ape no longer lay in wait beyond the hedge. After seeing the hounds, no one had wanted to be first to wriggle through to the other side. Thinking of those murderous claws, the beastcatcher had no intention of doing so either. There was a gap in the hedge some distance away, and he sent half the men to circle around. There was no sign of the beast other than three more mutilated hounds. In disgust Lycon hiked back to the caravan, letting the others follow as they would.

As he reached the road a shrill voice demanded, "Who's there!"

Lycon swore and yelled before nervous fingers released an arrow. "Don't loose, damn you! Fortune, that's all it would take!"

Vonones thumped heavily onto the roadbed from his perch on the wagon. His face was anxious. "How did it go? Did you get the sauropithecus? Where are the others?"

"Dragging-ass back," Lycon grunted wearily. "Vonones, there isn't one of your men I'd trust to walk a dog."

"They're wagon drivers, not hunters," the dealer protested. "But what about the lizard-ape?"

"We didn't get it."

And while the others slowly drifted back, Lycon told the dealer what had happened. The damp stillness of the dusk settled around the wagons as he finished. Vonones slumped in stunned silence.

Lycon's weathered face was thoughtful. "You got ahold of something from an arena, Vonones. I don't know whose arena or where it came from-maybe the Numidians raided it from some kingdom in the interior of Africa. But the way it moves, the way its claws are groomed-the way it kills for pleasure… Somebody lost a fighting cock, and you bought it!"

Vonones stared at him without comprehension. Licking his lips, Lycon continued. "I can't say who could have owned it, or what sort of beast it is-but I know the arena, and I tell you that thing is a superbly trained killer. The way it ambushed the dogs, slaughtered them without a wasted motion! And that thing moves fast! I'm fast enough that I've jumped back from a pit trap I didn't know was there until my feet started to go through. I knew a gladiator in Rome who moved faster than any man I've seen. He'd let archers shoot at him from sixty yards, then dodge the arrow, and I never could believe I really saw it happen. But that thing out there in the fields is so much faster there's no comparison!"

"How did the Numidians capture it, then?" Vonones demanded.

"Capture? Maybe they took its surrender! A band of mounted archers on a thousand miles of empty plains-they could have run it down and killed it easily, and that damned thing knew it! Then they welded it into an iron cage, and strong as it is, the lizard-ape can't snap iron bars."

"But it can pick locks," Vonones finished his thought.

"Yes."

The dealer took a deep breath, shrugging all over and seeming to fill his garments even more fully. "How do we recapture it, then?"

"I don't know."

Lycon chewed his lips, looking at the ground rather than at Vonones. "If the lizard-ape sleeps, maybe we could sneak up and use our bows. Maybe with a thousand men we could spread out through the hedgerows and gullies, encircle it somehow."

"We don't have a thousand men," Vonones stated implacably.

"I know."

Smoky clouds were sliding past the full moon. With dusk the drizzle at last had lifted; the overcast was clearing. A few stars began to spike through the cobwebby sky. Across the twilit fields, shadows crept out from hedgerows and trees, flowed over the rocky gullies.

"I can lay my hands on a certain amount of money at short notice," Vonones thought aloud. "There will be ships leaving Portus in the morning."

But Lycon was staring at the nearest cage.

"Vonones," the hunter asked pensively. "Have you ever seen a tiger track a man down?"

"What? No, but I've heard plenty of grisly reports about man-killers who will."

"No, I don't mean hunt down as prey. I mean track down for, well, revenge."

"No, it doesn't happen," Vonones replied. "A wolf maybe, but not one of the big cats. They don't go out of their way for anything, not even revenge. That's a human trait you're talking about."

"I saw it happen once," Lycon said. "It was a female, and one of my men had cleaned out her litter while she was off hunting. We figured later she must have followed him fifty miles before she caught up to him."

"She followed her cubs, not the man."

The beastcatcher shook his head. "He'd given me the cubs. The man was three villages away when she got him. Her left forepaw had an extra toe; there was no mistake."

"So what?"

"Vonones, I'm going to let that tiger out."

The dealer choked in disbelief. "Lycon, are you mad? This isn't the same at all! You can't…"

"Have you got a better idea? You know how all the animals hate this thing-that tiger even broke a tooth trying to chew his way to get at the lizard-ape. Well, I'm going to give him his chance."

"I can't let you turn yet another savage killer loose here!"

"Look, we can't get that blue-scaled thing any other way. Once it runs wild through a few more tenant holdings, Domitian isn't going to do any worse to you if you turn the whole damn caravan loose!"

"So the tiger kills the lizard-ape. Then I'm responsible for turning a tiger loose on his estate! Lycon…"

"I caught this tiger once. I know about tigers. This thing, Vonones…"

The dealer's hand shook as he turned the key over to Lycon.

Muttering, the drivers made an armed cluster in the middle of the road, watching Lycon as he unlocked the cage and vaulted to the roof as the door swung down. The tiger bounded onto the road almost before the door touched gravel. Tail lashing, he paused in a half-crouch to growl at the nervous onlookers. Several bows arched tautly.

Lady Fortune, breathed Lycon, let him scent that lizard-ape and follow it.

Turning from the men, the cat moved toward the other cage. He rumbled a challenge into the empty interior, then swung toward where the tracks stabbed into the damp earth. Without a backward glance, the tiger headed off across the field.

Lycon jumped down, boar spear in hand, and stepped across the ditch.
