"Regardless of that though, the lizard-ape almost certainly manned the steering oar until it drew close to Rome. At that point it may have then left the barge, but more likely it clung to the hull for the remainder of the distance. In the darkness, it might well have even hidden within the hold-it sees very well in the dark, you understand, while the teamsters had only sputtering rushlights for illumination. Quite possibly it left the barge only at the docks. Now the sauropithecus has all of Rome to hide in-and to hunt in."

Lycon downed half his wine. "An interesting theory. But why hasn't the lizard-ape been seen? And even if it's managed to hide, why haven't we heard reports of wholesale slaughter?"

"I warned you that the lizard-ape is extremely cunning," said N'Sumu, as his eyes returned to the mulling stove. He began scraping with one square-cut nail at the soot that coated the interior of the open cylindrical firebox.

"I think it will have found a lair-a ruin, an abandoned building, perhaps the sewers. I can't say where. But if it hunted by night, and killed only for food instead of sport… Well, how many murdered corpses greet the dawn from Rome's alleyways, or vanish forever during the night? I tell you again, these lizard-apes are very cunning."

"Well," said Vonones, holding in both palms the cup of warm wine from which he had not drunk. "Then we need to set up a reporting network in Rome like the one with which we've covered the countryside. That shouldn't be very difficult, Lycon, should it? We'll operate through the Watch commanders, offer rewards for any information that might be in point-mutilated bodies, or reports of disappearances that center upon one particular district. It won't cost us all that much-and if we do manage to learn something concrete about the lizard-ape's whereabouts, we can call in all our men from the countryside."

The hunter spat into the firebox of the mulling stove. The gobbet of saliva struck the bright metal where N'Sumu's finger had scraped away the soot. The spittle hissed in serpentine anger as it boiled away from the hot bronze. Lycon pointed the index and middle fingers of his right hand at N'Sumu's chest. "So you really think the lizard-ape's lurking about right here in Rome? I find that hard to accept, but it's a new tack, and maybe that will impress Domitian for a while at least. You know you're going to be standing there in the arena beside Vonones and me if this proves to be another waste of time."

"It's unlikely that I will end up in the arena," said N'Sumu, and the other two understood his threat. "I know I'm right. I'd capture the sauropithecus by myself, but I need good men, and that's why I chose to work through you. My authority from our lord and god is as great as may be required for my purposes. But you have the experience-" the smile spread across his face without showing any teeth beneath the broad lips "-of working in local conditions. And you will have the credit when we succeed."

Lycon swallowed the last of his wine without taking his eyes away from N'Sumu's face. "Then we'd better get started, hadn't we."

Lycon's tone gave Vonones the same feeling as would the sight of a lion in the grass-its body taut, its haunches raised slightly, and no part of it moving but the tip of its tail, quivering like the trigger that would shortly launch the beast upon its prey. But after blinking up at his friend, the merchant's gaze returned to the sizzling bronze that N'Sumu's bare finger had cleansed.

Lycon was running-running a hopeless race, for he knew his pursuer could run faster by far than he could. He wanted to risk a backward glance to see how close behind it was, but he knew that with that glance he would die.

The problem was these hedgerows. It was impossible to run when he had to crawl through all these hedgerows, one after another. Their branches already were slippery with blood, and their thorns tore at his flesh as Lycon plunged through. He told them he couldn't run any faster, but Domitian danced easily ahead of him-leaping over the hedges on his scrawny legs-and N'Sumu raced alongside him, laughing at him past his deformed smile.

"Old man! Old man! Old man! Old man!"

He had to keep running. He was too slow, too old-and he desperately feared the thing that pursued him.

There sat Vonones. The Armenian's stout chest had been folded open like a broken loaf of wine-soaked bread, and his hands kept fumbling inside his chest cavity in search of his missing lungs.

"Why didn't you kill it?" Vonones asked in a tone of betrayal. He held out a dripping bag of coins. "Didn't I pay you well?"

"I have to get through this hedge!" Lycon explained, plunging forward into the next thorny barrier.

Pamphilus, the first man he had ever killed in the arena, wagged his head back and forth upon its broken neck, and said: "Here's the door." But Lycon had seen the retiarius' net swimming through the air, and he bolted headfirst through the hedgerow instead.

The lizard-ape was waiting for him this time, and Lycon cursed himself for having paused to talk with dead men while the lizard-ape had vaulted the hedgerow. The lizard-ape had Domitian's face, and N'Sumu and Lacerta were carrying his bright-blue palanquin back and forth about the grain barge.

"You should have killed me when you had your chance," said the blue-scaled Emperor. His long talons reached out for Lycon's face, and needles of agony drove into the hunter's skull.

"Lycon! Lycon! Wake up!" Zoe was shaking him. "You're having another bad dream! Wake up! Please!"

Lycon opened his eyes, gaping at her stupidly. The nightmare was still full in his mind.

"What…?"

"A bad dream, Lycon." Zoe's face was taut with concern. "You're having another bad dream."

Lycon blinked into the darkness, recognized the familiar surroundings of their bedroom. He was sweaty and he was cold, and the familiar shakiness was returning.

"Can I get you something?" Zoe begged. She was slimmer than since they had married and more lovely than Lycon had ever remembered.

"Wine!" he muttered thickly. "Yes, wine. Bring me more wine."

Zoe slipped out of bed and opened the door. The lizard-ape was waiting for her there, and it tore off her face as casually as a man pulls off his hat.

"Zoe!" Lycon's scream pierced the night.

"Lycon! Wake up!" Zoe was shaking him. "You're having another bad dream! Wake up now!" At her breast, Glauce was wailing out her protest.

This time Lycon swung his feet to the floor and sat up-rubbing his face as if to scrape the nightmare from his eyes. Zoe anxiously massaged his shoulders and back, trying to ease the tension there. Lycon considered the opaque greyness within the apartment light shaft beyond his bedroom window, decided it was close enough to dawn. Pulling away from Zoe, he stood up and began to dress in the darkness. He would not risk sleep again this night.

"Where are you going?" Probably there would be no more sleep for Zoe, either. She was crooning to their daughter, trying to soothe her as well.

"Over to the compound. Vonones will be there soon, and maybe there'll be something to report from the Watch. Maybe something from our men who are still positioned between here and Portus. It was N'Sumu's great idea that we concentrate our search here in Rome."

He found her face in the dark for a quick kiss. "At least I get home nights now."

"I'd almost rather have you away on some collecting expedition," Zoe murmured. "I keep thinking you'd be safer off in some far wilderness, stalking the beasts you know."
