"Oak trees, yes; once the road starts ascending to higher ground at Bovillae, the trees get thicker. The top of the mountain is a veritable forest. I don't suppose you've ever seen a forest, Davus?"

"I've seen what they call groves, growing around temples in the city."

"Not quite the same thing. Well, so much for Bovillae. Not much to it, is there? Not a very special place to breathe your last breath, but that's where Clodius died the next day. The skirmish started farther up the road, but apparently Milo's men chased Clodius to the inn, where he made his last stand. According to Fulvia, it was a senator named Sextus Tedius who came along later and found the body lying in the road. He had his slaves put the corpse into his litter and sent it on to Rome. You and I saw the condition it was in when it reached Fulvia – stabbed and strangled. And after Bovillae, Eco? What's next on the road?"

"The land begins to rise, as you said. Wooded slopes with rich people's estates – pylons set on either side of private roads leading up to big houses that you can barely glimpse as you go by." He cocked his head and squinted. "Something new, closer to the road-a temple of some sort…"

"Not a temple, but a residence: the House of the Vestal Virgins. You're right, it's new, built only in the last few years. Before that, the Vestals lived somewhere higher up the mountain. There's a temple of Vesta somewhere up there. Not a place we men are likely to set foot in. Press on, imaginary rider. What's next along the road?"

"On the opposite side of the road… something else religious… having to do with women. A shrine, not a temple… a shrine to Fauna, the Good Goddess!"

"Excellent! A place for Fauna's female worshippers to leave offerings and make prayers, and another place where we wouldn't be particularly welcome. But according to Fulvia, it was on the stretch of road directly in front of the shrine of the Good Goddess that the skirmish between Clodius and Milo began. Well want to take a careful look at the lay of the land and see whether it looks like a suitable place for an ambush. But let's return to Clodius on the day before his death, on his way from Rome to Aricia. He'll have passed all these places, perhaps without stopping, wanting to press on now that he's so close to his destination. What comes next, Eco?"

"Hmm. I seem to remember some impressive pylons on the left and a road heading up to a villa on the ridge above."

"Yes. If my assumption is correct, that's where we'll be spending the night."

"Pompey's villa?"

"From the directions Baby Face gave me, I think that must be the place."

Eco whistled. "The view must be extraordinary."

"Yes. Pompey seems to like living in places where he's able to look down on the world around him. But don't stop yet What's next along the road?"

"More private estates. One of them must belong, to Clodius."

"Yes, his is that enormous thing that seems to perch on the side of the hill."

"The place where they cut down all those trees and did all that excavating?"

"Yes. Apparently a great deal of the interior space is underground, like a vault – defensible as a fortress, Fulvia told me. From what she said, I gathered that Clodius was especially proud of the place, even happier with it than that palace of a house on the Palatine. We'll get the chance to take a closer look at it. That's where Clodius's journey ended for the day, just a mile or so this side of Aricia. There must have been a few hours of sunlight left. Clodius probably inspected the grounds, talked to the foreman, saw to whatever it is that estate owners see to when they arrive at one of their estates. His cook, prepared a dinner that night to which some of the local elite were invited. It all sounds very respectable, very boring. After all that riding, little Publius junior probably fell asleep on his dining couch. The next morning, Clodius delivered his address to the town senate of Aricia, followed by a brief reception. Then back to his estate by shortly after midday or early afternoon. Fulvia says that he intended to spend at least another night there."

"Did he have more business in the area?"

"I don't know. Let's be sentimental and assume that he wanted to spend some fatherly time with his son, strolling through the wooded grounds around his villa. But then a messenger arrived."

"A messenger?"

"The one that Fulvia dispatched that morning, to give her husband the sad news about Cyrus the architect. She asked Clodius to return to Rome at once."

"Was it really necessary for Clodius to hurry home?"

"Fulvia seemed to think so. Cyrus was close enough to have named Clodius among his heirs, and Fulvia was depending on the man to finish their Palatine house. She felt overwhelmed by his death. She wanted her husband to come home."

"And Clodius dropped everything to come running at her call?"

"You don't find that credible, Eco?"

"I don't know, Papa. You've had more contact with the woman than I have."

"Yes, well, I’ll venture to say that when Fulvia tells a man to do something, the chances are good that the man will do what Fulvia says."

"Even Clodius?"

"Even Clodius. Which is to say that I find what Fulvia told me credible if not necessarily convincing: that Clodius intended to spend another night at his country villa, but instead found himself unexpectedly back on the Appian Way headed towards Rome, because of that message from Fulvia. If that was the case, then there was no premeditated ambush, was there? When Milo and his entourage passed by, Clodius should have been off strolling in the woods with his son; instead, Clodius was on the Appian Way, but only by chance."

"But where was his son, if the boy wasn't with him when the skirmish occurred?"

"Fulvia says that Clodius had promised the boy a stay in the country, and left him at the villa with his tutor."

"Does it strike you as credible that he would leave the boy behind, Papa?"

"Perhaps. You might think Fulvia would have wanted her son brought back to her, but the rich see these things differently. I suppose, if I owned a huge villa in the country with a full staff of slaves to run the place, I might feel comfortable leaving my eight-year-old son in their keeping. Or perhaps the boy is an insufferable brat and a terrible traveller. Perhaps he'd been a complete pest all the previous day and Clodius couldn't abide another long trip with the monster and wanted to be rid of him."

Eco laughed. "That's better! Forget the sentimentality."

"Of course, to some it might look suspicious that Clodius just happened to set out from his villa with an armed company just as Milo was approaching on the Appian Way, and just happened to leave his young son behind, out of harm's way. Another detail to be noted."

"So we finally come to Milo. What was he doing on the Appian Way?"

"You heard his speech in the Forum the other day. He was expected for a religious ceremony in Lanuvium, which is the next town you come to after Aricia, a couple of miles farther south. From what I've been able to tell, the bare facts of the account Milo gave at Caelius's contio are true: he attended a meeting of the Senate in Rome that morning and later he set out at the head of a large retinue, riding with his wife in a carriage. Milo claims they got a late start and didn't pass Bovillae until about the eleventh hour, the last hour of daylight. If that's true, it would seem to contradict Fulvia's story about Clodius heading home, because the eleventh hour of a winter day is too late for anyone with a scrap of sense to set out on a journey of several hours with a troop of men on foot. It would have been long after dark before Clodius got to Rome, and travelling by night is a dangerous business, if only because of the chance that a man or beast will trip in the dark and break a leg. So did the incident really occur that late? Fulvia says that Clodius's body, carried in a litter, arrived at her house on the Palatine at the first hour of the night – only an hour or two after Milo claims the skirmish began, which is impossible."
