In Monte Appennino, ad fontes Arni, a.d. VI Id. Mart., ad finem secundae vigiliae

The Apennine Mountains, at the source of the Arno, 10 March, end of the second guard shift, midnight

They continued on the ever narrowing road, one closely following the other, black figures in the reddish glow of the torch, moving over the snowy stretches. Publius Sextius forced himself to count the milestones, when they weren’t completely covered, and to keep a lookout for signs of animals that might attack them.

Oppressed by his solitude and worries, he turned to his companion.

‘Don’t you ever talk?’ he asked.

‘Only when I have something to say,’ replied Sura without turning, adding nothing further.

Publius Sextius went back to his thoughts, brooding over the revelation that had upset him most: that Mark Antony had been asked to participate in a plot against Caesar and, even though he hadn’t accepted, hadn’t told Caesar either. That could only mean one thing: he was on no one’s side but his own. Quite a dangerous quality in a man. Antony must have reasoned that, if the plot was successful, the conspirators would be grateful to him for his silence, and if it failed, he would have lost nothing. But how, then, to explain that gesture of his at the Lupercalia festival? If he was really so smart and so cynical, how could he have committed such a huge error? He had chosen to stand out by making such a blatant move at such a sensitive moment. Perhaps he’d always deliberately acted the part of the simple soldier, who knows nothing of politics, in order to hide his bigger ambitions. But even if that were so, what sense did it make to attempt to crown Caesar king in public? Evidently Antony had known, or had thought he knew, how the crowd would react, so why didn’t he worry about Caesar’s reaction? Even if he thought he could continue to hide behind his pretended ingenuousness, Antony couldn’t ignore the fact that — if a conspiracy was being planned — his gesture would contribute to making Caesar more vulnerable and more alone.

So why had Antony chosen to do such a thing? What could the reason possibly be?

Publius Sextius continued turning it over in his mind, again and again, but it was like beating his head against a wall. Finally, he gave up and instead watched the snow descending silently in huge flakes in the light of Sura’s torchlight as they proceeded slowly, ever more slowly, while he would have preferred to race like the wind, to devour the road, to reach his destination before it was too late. Maybe it was already too late. Perhaps all his efforts would prove to be in vain.

There had to be a reason. Fleetingly, when the vice loosened and the cold air let him breathe, he felt he was close to finding a solution. The answer must lie with several key people, not many, perhaps three or four. With the balance of power or interests among them. He forced himself to consider every possibility, the likely motives of each individual and how they might overlap or conflict. He would have liked to jump to the ground and use the tip of his knife to sketch out the complicated connections on the immaculate snow, in the way that he would use the hard ground of an army camp to plan the action for his unit during a battle. But then he would lose track and his thoughts would dissolve into thousands of small, confused fragments, at which point he would realize he was no closer to a solution than he had been at the start and his gaze would drift again to the spinning white flakes.

Now and then he even suspected that the map Nebula had given him in Modena, before disappearing into the morning fog, was leading him straight into a trap. But even if that were so, he convinced himself, he had no choice and had to run this risk. The alternative was arriving too late to pass on his message.

Sura now broke one of his interminable silences to announce that they were close to the source of the Arno river and were on an ancient Etruscan road. He said nothing more.

Publius Sextius rode on, torturing himself with his thoughts all night long.

In Monte Appennino, a.d. V Id. Mart., tertia vigilia

The Apennine Mountains, 11 March, third guard shift, after midnight

Only Rufus was suffering as much pain as he struggled to reach the Via Flaminia Minor in as little time as possible, which meant cutting straight across the mountainside. At first he followed the barely visible path that wound down the slope forming the western embankment of the Reno valley to get to the river. He managed this with considerable difficulty, often having to dismount and lead his horse by the reins, until he arrived at the riverbank. The weather had taken a turn for the worse. The falling snow was now mixed with a fine, relentless drizzle that trickled down his cloak and dripped on to the ground from the hem.

He found the ford by following the sound of the water rushing between the rocks and urged his horse into the river. The water deepened at the centre, rising to the horse’s chest, but they were soon treading on a bed of fine gravel and sand, having reached the opposite bank.

The path on that side ascended steeply, but when Rufus met up with the snow again the low glimmer of the white blanket helped him to get his bearings, enabling him to set forth on the path he had used so many times before. He soon reached the hut of a shepherd he knew well and he stopped there to drink a cup of warm milk and eat a chunk of bread and cheese. The cabin was lit inside by the flames in the hearth. Its walls, plastered with dried mud, were completely blackened by the smoke. The whole place stank of sheep, from his host to the hulking Molossian hound lying on the ash that circled the hearth, a hairy beast that everyone called by a different name. Rufus scratched him behind his flea-ridden ears by way of greeting.

‘What are you doing out here at this hour?’ asked the shepherd, in a mix of Latin and his Ligurian dialect that not everyone could decipher.

‘I have an urgent message to deliver,’ replied Rufus between one mouthful and the next. ‘What’s it like on the summit?’

‘You’ll be able to make it over, but be careful. I’ve seen a pack of wolves up there: an old male, two or three young ones and four or five females. They might get brave in the dark and latch on to your horse’s hocks. You’d best take a brand from the fire and make sure it doesn’t go out until you’ve reached the top.’

‘Thanks for the warning,’ said Rufus.

He left a couple of pennies for what he’d eaten and drunk, then, with firebrand in fist, he went back out into the open. At least here he felt that he could draw breath again, clearing the foul stench that had saturated the hut and filled his nostrils.

He took his horse by the reins and started to make his way up on foot, lighting his path with the brand he held high in his left hand. He wondered from what distance the light could be seen. Perhaps at that very moment his commander was standing on the upper terrace at Lux fidelisand looking his way. He could almost hear him cry out, ‘There he is! I’ll bet a month’s pay that that bastard has already made it to the crest!’

He didn’t have far to go, in fact. Up ahead, less than half a mile away, a group of towering firs marked the ridge.

His horse was the first to sense the wolves and Rufus saw them himself an instant later, the flaming brand reflected in their eyes with a sinister gleam. He didn’t even have a stone to throw at them and they didn’t look likely to retreat. He shouted and waved the brand. The wolves ran, but stopped just a few paces further away.

Rufus shouted again, but this time the wolves did not retreat. In fact, they began to circle around him, growling. This did not bode well. They were carrying out the pack’s strategy for isolating prey and attacking. And he was their prey, or the horse, or both of them.
