Sejanus planned to eliminate Caligula, the more prominent of the Emperor's heirs. If the old man refused to die of his own accord, the Guard commander clearly intended to destroy Tiberius himself.

The dictation completed, Caenis managed to keep her face expressionless. At a brusque nod from Antonia, she fetched the necessary materials from her workbasket and absorbed herself in the letter's careful transcription to a scroll.

Pallas, Antonia's most trusted slave, came into the room, dressed in a traveling cloak and clearly primed to collect the letter. Their mistress motioned him to wait in silence while Caenis completed her task. Newly confident, she copied her notes without mistakes, writing calmly and steadily even though her mouth felt dry and her cheeks flushed. What she was committing to ink and parchment could be a death warrant for all of them.

Antonia read through and signed the letter. Caenis melted wax to seal the scroll. Pallas took charge of it.

"Do not let this fall into other hands," Antonia reminded him, obviously repeating previous instructions. "If you are stopped, say you are traveling to my estate at Bauli. Give the letter only into the Emperor's own hands, then wait in case he wishes to question you."

The messenger left. Pallas was not a type Caenis cared for. He was a Greek from Arcadia, visibly ambitious, whose appeal to Antonia struck her as incongruous. He went on his way with a jaunty step that seemed out of place. But perhaps his carefree manner would disguise the importance of his mission from soldiers and spies.

The two women sat for a moment.

"Remove every trace from your note tablets, Caenis."

Caenis held the tablets above the flame of a lamp to soften the wax a little, then methodically drew the flat end of her stylus through each line of shorthand. Staring at the newly smoothed surface, she said in a low voice, "It is useless, madam. I would have erased the letter in any case, but every document you ever dictate to me remains in my mind."

"Let us hope your loyalty matches your memory," Antonia replied ruefully.

"You may have faith in both, madam."

"That will be fortunate for Rome! You will remain in this house," Antonia stated. "You may speak to no one until these matters are resolved. It is for the safety of Rome and the Emperor, for my safety—and for your own." Faint distaste colored her voice: "Do you have male followers who will look for you?"

"No, madam." Only that morning Caenis had encountered a man who might have troubled her thoughts for many long hours, but tonight had obliterated that. "I have one friend," she went on, matter-of-factly contributing to the discussion. "A garland girl called Veronica. She may come asking about me, but if the door porter says I am working for you, madam, she will be satisfied." Veronica had never taken any interest in Caenis' duties as a scribe.

"Well, I am sorry to have to imprison you here."

"I shall try to endure it, madam," Caenis replied, smiling. She might as well acknowledge what it would mean to be living in Livia's House.

There was nothing for them to do. It would be weeks, if not longer, before Pallas reached the Bay of Naples and the Emperor reacted. The messenger might never get there.

Even if Pallas did reach Capri, from all Caenis had heard there must be a good chance that Tiberius would choose to reject what Antonia was telling him. He was moody and unpredictable, and nobody likes to hear they have been betrayed. Even if Antonia's measured words convinced him, there might be nothing he could do; the Praetorian Guards held absolute power in Rome. Arresting their commander appeared to be impossible. They would defend Sejanus to the last.

His agents were everywhere. Only the unexpectedness of Antonia's action could possibly outwit him.

THREE

For Caenis this was in many ways the most significant period of her life. It all seemed too easy. Everyone looked too happy to welcome her. Caenis, who distrusted smiles, felt off balance for some time.

Living in a private house was wonderful. She had been allocated her own tiny sleeping cubicle instead of sharing with Veronica. She liked both the sense of belonging and the privacy.

Born and bred in the Palace, Caenis could have no country and no relations of her own; she was one of "Caesar's family," but that title just made her imperial property. In some ways it had been good luck. It had spared her the indignity of standing naked in the marketplace shackled among Africans, Syrians, and Gauls, with notes of her good character and health hung around her neck while casual eyes derided her and rough hands pinched her breasts or forced between her thighs. She had escaped long-term insecurity, real filth, savage cruelty, regular sexual abuse. She understood that; she was grateful up to a point.

Of her father she knew nothing; of her mother only that she must have been a slave too. Caenis had presumably stayed with her mother while she was very small; sometimes a smear of memory would catch her on that threshold between waking and shallow sleep. Before she was committed to the nursery where bright brats were taught to write, her mother had pierced her ears, even though all she had to hang there were pebbles on rags of string. She must have supposed her daughter was then ready to receive orbs of gold from susceptible men. There was always that foolish presumption that a slavegirl must look pretty. Caenis never had been; she knew her cleverness was the better bargain, but it made her sad all the same.

She had been clever from the start. As a child frighteningly so. She learned to disguise it, to escape spite in the children's dormitory, then later to use it so a usefully vibrant girl like Veronica would want to be her friend. Though a solitary child, she understood that she needed other people. As she grew older her resentments had dulled, so she neither tormented herself nor worried the overseers by appearing rebellious. But she possessed a keen drive to achieve the best she could.

That was why working for Antonia was so important. Encouraged by the new confidence now placed in her, Caenis began to acquit herself outstandingly. Having once caught Antonia's notice, every opportunity was hers. Straight-backed and calm, she worked as if nothing significant had happened—winning further trust from her mistress for her restrained reaction to events.

Diadumenus, who must have been told what had happened, showed occasional signs of jealousy. He was still Chief Secretary, but Caenis had a special quality to offer. She was a woman, and Antonia at seventy was short of female companionship. Her lady wanted neither a chit she could bully nor a monster who would try to bully her. Antonia needed someone with good sense; someone she could talk to; someone she could trust absolutely. She had found all that, though she did not yet know Caenis well enough to admit it. But they had shared an act of bravado (and of tragedy too, for Antonia had condemned her own daughter). They were now locked in a secret, awaiting the outcome. And if Sejanus discovered that Antonia had denounced him, there would be fatal results for both mistress and slave.

Life went on. An appearance of normality was crucial. Visitors came and went. For secrecy's sake Caenis was forbidden to approach them but since she was tied to the house she was volunteering for any work she could. This included keeping a diary of visitors. Caenis was a secretary who could remain virtually invisible—while thoroughly inspecting all the persons whose names featured on her lists.

Among Antonia's private friends were wealthy men of consular rank such as Lucius Vitellius and Valerius Asiaticus, who sometimes brought clients of their own. Caenis soon spotted among the names of Vitellius' escort that of Flavius Sabinus, one of the two young men she had directed at the Palace. He currently held the civic post of aedile, so he qualified for an introduction here, although actually gaining admittance had required the patronage of a much more senior senator. This unofficial court circle could be a good place for impoverished new men from the provincial middle class to acquire influence. Here they would be meeting Caligula and Gemellus, the heirs to the Empire. They would mingle with ambassadors. They could even, if they wanted to risk ridicule, make the acquaintance of Claudius, Antonia's surviving son, who because of various disabilities took no part in public life.
