My interview with Terentia and the Vestal Fabia had yielded some new information about Cassandra, if not much. I decided next to consult Fulvia the twice-widowed; I had rendered her a service in the past by investigating the murder of her husband, Clodius-as partial payment she had given me Mopsus and Androcles-and I could expect at least a cordial welcome at her door. And so, after leaving Cicero's house and returning to my own for a frugal midday meal and a fitful nap during the hottest part of the day, I set out as the sun was lowering to the house of Rome's most famous widow.

As before, I took Davus with me for protection. As we walked down the familiar streets of the Palatine, I was reminded of the days when Davus first entered my household as a slave, only shortly after I first met Fulvia as a stunned and grieving widow. It seemed a memory from another age. Could it actually have been only four years ago that Clodius was murdered on the Appian Way? Rome had been wracked with riots. Clodius's radical supporters had burned the Senate House. Pompey had been called upon to restore order and given almost dictatorial powers; he had exploited the situation to engineer a series of trials that banished many of his enemies from Rome, upsetting once and for all the precarious constitutional balance between his interests and those of Caesar. In retrospect, the murder of Clodius had been the temporal fulcrum between the moment when civil war seemed unthinkable and the moment when it became inevitable. The murder of Fulvia's first husband had been the beginning of the end of our tattered Republic.

Her grief for Clodius had been deep and genuine. They had been true lovers, I think, as well as partners in a broader sense; for Fulvia, as a politician's wife, had always been the exact opposite of Cicero's Terentia. She was a woman with opinions, plans, projects, allies, and enemies. She plotted and schemed alongside her husband and served as his closest advisor. His death had robbed her not only of a husband and a father to their two children; it had robbed her of her role in the political sphere. Women can play no part in the Senate or the magistracies. Women cannot vote. By law they cannot even own property in their own names, although clever women find ways around such technicalities, just as women who care about the course of worldly events find ways to wield their influence, usually through their husbands. While Clodius lived, Fulvia had been one of the most powerful people in Rome, male or female. When he died, she was like a strong man suddenly paralyzed and stricken mute.

But a woman as intelligent, wealthy, and ambitious as Fulvia-who was also a striking woman, if not beautiful-did not have to endure the helplessness of widowhood for long. To a certain kind of man, her combination of qualities must have been almost maddeningly attractive. When she consented to marry Gaius Curio, many people thought that she had found the perfect match. He had been a part of her circle for many years, one of that coterie of ambitious, bright young men with voracious appetites and endless schemes to remake the world in their own image, men like Dolabella, Clodius, Caelius, and Marc Antony. Some said that Fulvia actually would have preferred Antony, had he been available and not already married to his cousin Antonia, and that Fulvia had settled on Antony's boyhood friend (some said lover) Curio as the next best thing; but most agreed that Curio was in fact the better choice because he was more malleable and less inclined to debauchery than Antony.

Like Antony, Curio early on allied himself with Caesar and never wavered in his devotion or relented in proselytizing on Caesar's behalf. Indeed, it was largely Curio's influence that had brought Marcus Caelius into the fold. On the eve of the war, Caelius and Curio had ridden out together to be by Caesar's side when he crossed the Rubicon. But while Caelius had ultimately been relegated to a minor praetorship in Rome, Curio had been given command of four legions. When Caesar headed for Spain, he dispatched Curio to take on the Pompeian forces led by Cato in Sicily. Cato, disorganized and unready like the rest of the Pompeians, abandoned the island without a fight. Curio, flush from an easy conquest, left two of his legions in Sicily and with his other two pressed on to Africa-and that was where Curio's troubles began.

Some said his conquest of Sicily had been too easy, that it led to overconfidence and rash judgment. Some said it was Curio's youth and lack of military experience that led him into King Juba's trap. Others said it was simply bad luck.

Curio's African campaign began well enough. First, he set about taking the rich seaport of Utica, which was held by the Pompeian commander Varus. A small band of Numidian soldiers dispatched by King Juba attempted to come to the city's aid, but Curio drove them off. He baited Varus to meet in battle outside the city. There Curio made his first mistake, which only by a stroke of good luck proved not to be fatal. He sent his foot soldiers into a steep ravine where they might easily have been ambushed; but in the meantime his cavalry managed to sweep away the enemy's left wing, and Varus's men-sent fleeing back to the city-missed an easy opportunity to destroy their enemy. Such a near miss might have given Curio pause, but instead it emboldened him. He prepared to lay siege to Utica.

In the meantime, King Juba had mustered his army and was marching to relieve Utica. Juba had close ties to Pompey, having been a patron of Pompey's father. And he had cause to hate Curio, who in recent years had proposed that Rome should annex Numidia by force.

Curio received news of Juba's approach. Alarmed, he sent to Sicily for his other two legions. But deserters from Juba's army told him that only a small body of Numidians were advancing. Curio sent out his cavalry, who skirmished with Juba's vanguard. From the intelligence he received, Curio thought that this vanguard was the whole Numidian force. Thinking to destroy it so that he could get on with the siege, he hurried out with his legions to do battle. The season was blisteringly hot; the march over burning sands. The Romans blundered into the entire Numidian army. They were surrounded and slaughtered.

A handful of Curio's men managed to escape. Curio, too, might have fled and saved himself, but he refused to desert his men. A survivor, bringing news of the disaster to Caesar shortly after Caesar's return from Spain, reported Curio's last words: "I've lost the army Caesar entrusted to me. How could I face him?"

Curio fought until the Numidians killed him. They cut off his head and sent the trophy to King Juba. Fulvia was once again a widow.

Pondering her situation, imagining her mood, I felt some hesitation as I approached her house. The structure itself presented a daunting aspect-the giant, fortress like monstrosity that Clodius had erected on the Palatine, the opulent headquarters from which he had directed the street gangs under his command. Steep terraces overgrown with roses and glimmering with many-colored marble veneers flanked the huge forecourt that had served as a rallying place for Clodius to address his supporters. The iron gate stood open, and as Davus and I strode across the forecourt, gravel crunching under our feet, I gazed ahead at the flight of steps leading up to the broad porch and saw a black wreath upon the massive bronze door. Nine months into her widowhood, Fulvia was still in mourning for Curio.

We mounted the steps. A huge bronze ring on the door served as a knocker. Davus lifted it and let it fall, delivering a dull, reverberating clang. We waited. So far as I could see, no peephole opened in the door, but I had the uncanny sensation of being observed. Clodius's passion for installing secret passages, concealed doors, and hidden spy holes had been notorious.
