Lost in thought, Lucius wandered homeward. Turning a corner, he realized that he was very near the house of Brutus. An impulse had caused Lucius to call upon Cleopatra. An equally spontaneous impulse now prompted him to pay a visit to Brutus, who, according to rumor, was another of Caesar’s possible heirs.

Everyone knew that Caesar had been the lover of Brutus’s mother, Servilia. The fact had come out before Lucius was born, and on the floor of the Senate, of all places. Servilia was the half-sister of Cato, grandson of the famous Cato who had called for the destruction of Carthage. Cato had been one of Caesar’s bitterest enemies. Twenty years ago, during a heated debate in the Senate regarding an alleged conspiracy by the populist Catilina, Caesar had been seen to receive a note from a messenger. Cato, suspecting it might implicate Caesar in the plot, insisted that he read the note aloud. Caesar refused. Cato grew more suspicious and more vehement, until finally Caesar relented and read the message aloud. It was a love note from Servilia, Cato’s sister. Cato was humiliated. Caesar was much amused. From that day, his affair with Servilia was public knowledge, and the speculation began that he might be the father of her son, Marcus Junius Brutus. The special regard in which Caesar had always held Brutus, even when Brutus sided with Pompeius, had further fueled this speculation.

Whatever their relationship, Brutus was among the men whom Caesar had chosen to fill various posts when he began rebuilding the government. Currently Brutus was praetor in charge of the city, but in the coming year he would leave for Macedonia to serve as provincial governor. Because Caesar’s Parthian campaign might keep the dictator from Roma for an indefinite period, all such appointments had been made not for the usual one year but for five years.

Brutus was also a key member of the Senate, and it occurred to Lucius that he might already have left home, heading for the Field of Mars and the meeting of the Senate at the assembly hall in the Theater of Pompeius. But evidently Brutus was still at home, for as Lucius drew nearer to Brutus’s house, he saw several men in red-bordered senatorial togas being admitted at the front door. Lucius assumed they must be gathering before heading off in a group to the assembly hall. Clearly, it was not a good time for Lucius to pay a visit. Nonetheless, he continued in the same direction, toward Brutus’s house.

Suddenly he heard the sound of many footsteps behind him. A large group of men caught up with him and swept past him. Lucius saw a blur of togas, and glimpsed several familiar faces. Some of the senators must surely have recognized him, but not one of them uttered a greeting. They averted their eyes from him. As they hurried on, whispering among themselves, he thought he heard them speak his name. It was very strange.

The senators reached the house of Brutus, rapped on the door, and disappeared inside.

Lucius arrived at the threshold and stared dumbly at the door. What was going on in the house of Brutus? Something was not right. It occurred to him that the senators might have been bringing bad news—something to do with Caesar, perhaps? Lucius gathered his nerve and rapped on the door.

A peephole opened. Lucius gave his name. He was perused by a pair of unblinking eyes. The peephole closed. Lucius was left waiting for so long that he decided he had been forgotten, and was about to leave. Then the door opened. A grim-looking slave admitted him to the vestibule.

“Wait here,” said the slave, and disappeared.

Lucius slowly paced back and forth. He looked at the busts of the ancestors in their niches, paying only scant attention until he saw one that was clearly honored above all the others, placed in a special niche with votive candles in sconces at either side. The mask looked very, very old. It was a famous face, known to every Roman from public statues all over the city.

“That’s only a copy, of course,” said a voice. “Wax masks don’t last forever, and more than one branch of the family lay claim to him, so there had to be duplicates. Still, that mask is very ancient, and very sacred, as you can imagine. The candles are kept lit always, day and night.”

Brutus stood before him. Curious to see if he could detect a resemblance, Lucius looked from the face of Brutus to the face of his famous ancestor and namesake—the man who had been the nephew of the last king, Tarquinius, who had revenged the rape of Lucretia, who had helped to overthrow the monarchy and had become first consul, who had watched his own sons be put to death for betraying the Republic.

Lucius frowned. “You don’t look anything alike, as far as I can see.”

“No? Even so, I think we may share a similar destiny. At any rate, his example inspires me, especially today.”

Was Brutus feverish? It seemed to Lucius that the man’s eyes glittered unnaturally.

“Why have you come?” said Brutus.

“I’m not sure. I happened to be passing. I saw your visitors arriving. It seemed to me that something…that perhaps something was wrong…”

His voice trailed away as another man appeared behind Brutus. Gaius Cassius Longinus was Brutus’s brother-in-law, married to his sister. He was one of the senators who had swept past Lucius in the street. Lucius nodded to him. “Good day to you, Cassius.”

Cassius did not return the greeting. He whispered in Brutus’s ear. He looked tense and pale.

The two exchanged more whispers, and cast furtive glances at Lucius. They appeared to be arguing and trying to come to some decision. Lucius began to find their scrutiny unnerving.

Brutus gripped Cassius’s arm and pulled him to the far side of the room, but his whisper was so loud that Lucius overheard. “No! We agreed already—Caesar and only Caesar. No one else! Otherwise, we show ourselves to be no better than—”

Cassius cast a cold gaze at Lucius, silenced Brutus with a hiss, and pulled him into the next room.

If they were still whispering, Lucius could not hear; his heartbeat was suddenly so loud in his ears that he could hear nothing else. He looked toward the front door. It was blocked by the grim-faced slave. From the atrium, more slaves appeared, followed by Brutus.

“Don’t harm him!” Brutus shouted. “I only want him restrained. We’ll hold him here until—”

There was no time to think. A thrill of panic ran through Lucius and he acted purely by instinct. He bolted toward the door, but hands on his arms and shoulders held him back. He tried to shrug them off, but the hands gripped him more firmly. With all his strength he pulled free, turned around, and swung his fists. His knuckles connected with the hard jaw of one of the slaves and sent a painful shock through his arm. The slave took a swing at him in return and struck a glancing blow across his shoulder. Lucius struck the man square in the face. The slave staggered back, blood pouring from his nose.

Now only the slave barring the door stood in his way. Lucius ran toward him, lowered his head, and butted the man in the stomach. The slave cried out in pain and bent forward, clutching his belly. Lucius pushed him out of the way and managed to slip through the doorway, into the street.

He meant to run in the direction of Caesar’s house, but there were already men in the street, blocking his way. He turned about and ran in opposite direction, away from the Forum, away from the Field of Mars and the Theater of Pompeius.

Lucius was young and quick, and he knew the streets of the Palatine well. He gained a good lead on his pursuers. He rounded a corner, and then another, and could not see them behind him at all. But he was growing weary; he needed refuge. He realized that he was near the house of Publius Servilius Casca. Surely he could trust Casca, who was deeply indebted to Caesar. The rotund, red-cheeked, bumbling Casca was something of a buffoon. It was impossible to imagine him as a menace to anyone.
