Tiro squinted. "I'm not sure. I know the insignia of every cohort and legion, but they're not close enough for me to tell."

"They soon will be, at the speed they're marching. There must be thousands of them! The column goes on for miles. I can't see the end of it." I looked back at the wagon. "I suppose we'll have to pull off the road as best we can and wait for the whole army to pass. That could take all day."

Tiro fretfully shook his head. "What does it mean? They don't have the look of a defeated army, that's for sure. Too disciplined. Too many of them! If they're Pompey's men, they can't have reached the mountains without encountering Caesar. That can only mean that Caesar's been defeated. Pompey's crushed him, and now Pompey and the senators who fled are heading back to Rome. The crisis is over- if this is Pompey…"

I nodded, wondering what that would mean to Davus, to Meto. The tramping and clattering grew louder moment by moment, booming and bouncing across the rarefied mountain air until it seemed to emanate from the empty sky like constant thunder.

"And if they're Caesar's men?" I asked.

Tiro shook his head. "I don't know. Maybe Pompey escaped from Brundisium before Caesar could reach him, and now Caesar has turned back, empty-handed. Or did Caesar trap him there, annihilate his forces, and then turn back toward Rome? But there can't have been time enough for a siege. It makes no sense. These must be Pompey's men…"

He sucked in a breath. "Numa's balls!" Tiro cursed so rarely that I stared at him in wonder. His face was ashen. "Of course! Not Pompey's men, and not Caesar's either!"

"Tiro, you're making no sense."

"There, do you see those advance scouts riding ahead of the rest? See the band of polished copper around their helmets?"

I squinted. "I can't quite-"

"I'm sure of it: a copper band. And the officers will have copper disks on their breastplates, showing a lion's head. Domitius owns copper mines. These are his cohorts, the men who betrayed him in Corfinium."

"Coming after Domitius to claim lost pay?" I suggested.

Tiro was not amused. "Perhaps they've turned against Caesar. But no, surely they'd be marching to join Pompey, if that were the case." He looked frantically back at the wagon, where the driver and Fortex stared up at us, perplexed. "Infernal Pluto! There's no way we can hide the wagon- the road's hemmed by boulders and trees, and we haven't passed a branch road for miles." He shook his head. "I should have traded the driver and wagon for horses this morning. On horseback, we might have had some chance to hide ourselves."

"Does it matter? We could simply be innocent travelers crossing the mountains."

"On this road, Gordianus, there are no innocent travelers."

He seemed close to panic. I tried to calm him. "We'll hide among the rocks, Tiro. The driver can stay with the wagon and tell them he's traveling alone."

"The driver would tell them everything at the first rattle of a sword."

"Take the driver with us, then."

"And leave an abandoned wagon by the side of the road? That would be even more suspicious. They'd be sure to search for us then, and they'd find us in minutes. How would that look- four men with something to hide, skulking in the woods?"

"You're right. We have no choice but to stay with the wagon. When the advance scouts arrive, we'll wave and smile and remark on what fine weather we're having."

Tiro took a deep breath. "You're right. We must simply brazen it out. You'll be the master and I'll be your slave. Why shouldn't you be heading for Caesar's camp? You have a son under his command."

"Yes, that's the story, all the better because it's partly true. First, I suggest we leave this hilltop. Peering down at them like this- it makes us look like spies, don't you think?"

He managed a crooked smile. "Start back without me. I need to relieve myself."

"Go ahead. Don't be shy."

He winced. "No, Gordianus, it's not my bladder. A fright like this- it goes straight to my bowels."

Tiro hurried into the woods. I cast a final look at the endless stream of men pouring up the mountain, then scrambled down the hillside and rejoined the others.

Tiro arrived at the wagon just before the first scout on horseback came through the pass. The soldier rode slowly toward us, warily scanning the trees and boulders behind us. He stopped several paces away.

He noted the iron ring on my finger. "Who are you, citizen? What business do you have on this road?"

"My name is Gordianus. I'm traveling from Rome. Are you one of Caesar's men?"

"I'll ask the questions, citizen. Who are these others?"

"The driver comes with the wagon. I hired both from his master, at an inn on the other side of the mountains. We weathered a nasty storm, let me tell you. May the gods grant you fairer skies than we had."

"And these others?"

"Slaves. That one's a bodyguard, as you can tell by the look of him. A good thing I brought him along. We weren't a mile out of Rome when some bandits attacked us; would have killed us if they had the chance, I'm sure. But we haven't had a bit of trouble since."

"And the dark one?"

"Another slave. A philosopher. His name is Soscarides."

The scout looked at us disdainfully. He was the sort who had little use for civilians. "You still haven't stated your purpose for being on this road."

I looked at the copper band around his helmet and cleared my throat. He and his fellows had once been loyal to Domitius. Now he had sworn allegiance to Caesar- or so we presumed. What if we were wrong? What if Domitius's troops had turned on their new master? Caesar might be dead, for all we knew, and these troops might be marching back to Rome with his head on a stake. But I had to give the man an answer. I thought of the gamblers in the Salacious Tavern back in Rome, casting dice and crying "Caesar!" for luck, and I took a deep breath.

"I have a son in Caesar's service, on his personal staff. Soscarides here was the boy's tutor when he was young. Call me soft, but I can't stand the worry any longer- can't stand waiting idly in Rome for news. So here I am."

"You're looking for Caesar, then?"

"Yes."

The man looked at me sternly for a long moment, then came to a decision. He smiled." Just keep following the road then, citizen. You'll find him." His tone changed as completely as his face, like an actor putting aside a mask.

"At Brundisium? That's the rumor along the road."

He smiled but didn't answer. He was ready to be friendly, but not that friendly.

A second scout rode up. The two of them withdrew to the far side of the road and conferred, casting glances at us. The second scout rode on. The first returned. "You might as well get comfortable, if you can. You'll be here for a bit. Some troops will be marching past."

"Are there many?"

He laughed. "You'll see. I'll stay here with you until the head of the column arrives. No need for you to answer the same questions for my commander. He'll decide whether or not to cut your heads off." He grinned to let me know it was a joke.

I glanced at Fortex, who snorted to show that he wasn't impressed. Tiro looked calm- philosophical, even. The driver looked nervous.

The column came up through the pass. We saw horsehair-crested helmets first, then the officers who wore them, mounted atop magnificent chargers. They were followed by drummers. The steady tattoo of the marching beat reverberated between the steep hillsides. The officer wearing the helmet with the most elaborate crest signaled to the others to proceed while he broke from the column and cantered over to the wagon. A lion's head roared from the copper disk on his breastplate.

"Report!" he said to the scout, who saluted him crisply.

"A traveler from Rome and three slaves, cohort commander. The man's name is Gordianus."
