Urbana's clipped, precise speech drew to a close, and she turned to Claudia, scrutinising her curiously.

'Claudia enjoys my full confidence,' Helena murmured softly, 'as does Murranus.'

Claudia decided not to wait for Urbana to deliver another speech. 'You have come from the Villa Carina?' she asked. 'Senator Carinus must be distraught and angry. How did his daughter's abductors gain access? Surely there were guards?'

Urbana gestured at Theodore, who was almost jumping up and down on his cushioned stool, eager to speak. 'There were guards,' the actor declared as if delivering the prologue to a play. 'Senator Carinus had hired some bully-boys, but they were quite drunk. It was I who raised the alarm.'

'Tell me,' Claudia interrupted, 'what exactly happened?'

'I was with Antonia in her private part of the garden near the Fountain of Artemis. We were discussing Seneca's Oedipus. Suddenly,' Theodore flailed his hands, 'out of the trees slunk these walking shadows, phantasms of Hades.'

'The attackers?' Claudia demanded, trying to keep her face straight.

Cassia had now lowered her beautiful head, that mop of golden hair hiding her face, and her shoulders were shaking.

Leartus was chewing on his lip but his eyes were bright with laughter.

'The attackers?' Claudia repeated.

'They were dressed in leather kilts, bare-chested except for belts and baldrics. Actors' masks covered their faces as if they were characters from one of Terence's comedies. I-'

'Then what happened?' Helena snapped.

Theodore remembered himself and some of his dramatic flourishes ceased.

'They grabbed Antonia. I attacked one and dragged off his mask. I saw his face in the torchlight, bearded and scarred; his nose was broken, his lips puffed out, a former boxer surely?'

'When you join us at the She Asses,' Claudia remarked, 'you must give us that description again. Perhaps there is someone there who might recognise it.'

She paused, studying Theodore intently. She had no evidence, nothing but her own instinct, yet she was sure the actor was lying. She had lived, eaten and worked with the likes of Theodore from Ravenna in the north to Tarentum in the south. They were all the same: good people, but they lived for the performance, the show, whatever that might be. So if Theodore was lying, why? To win the favour of Carinus so that he'd be lavishly rewarded as the saviour of the hour, the great hero, a story he could dine out on in the wine booths of the city? Or was he part of the conspiracy? She recalled those heavy masks actors wore; they were usually strapped very firmly to the face. Had Theodore really pulled one off? If not, and she really believed he hadn't, why did he mention it?

'Then what happened?' she asked softly.

Theodore nursed the side of his head. 'I received a blow.' He assumed all the airs of a victim. 'I fell down. I was in great pain, confused. By the time I recovered, Antonia,' his voice broke dramatically, 'Antonia,' he sobbed, 'was gone! Those creatures of the night had taken her!'

'They came and left.' Urbana spoke up. 'I questioned Senator Carinus, his stewards and freedmen. He,' Urbana flicked her fingers at Theodore, 'raised the alarm, but it was too late.'

Claudia rocked backwards and forwards on her stool. Helena glanced swiftly at her. Good little mouse, the Empress thought, sitting in the corner watching and hearing everything. All the time your sharp mind nibbles away at what you observe!

'They must have known.' Claudia raised her head. 'The abductors, they must have known where to go. You said Antonia was in her private part of the garden. Why did they go there? Somebody must have led them to it.'

Theodore, realising he may have placed himself under suspicion, swallowed hard and nodded.

'Someone must have told them,' Claudia insisted. 'Senator Carinus,' Leartus spoke softly as his mistress' lovely fingers made their intricate signs, 'Senator Carinus,' he repeated, 'had hired servants for that night, porters, lamplighters, scullions and maids.'

'Ah yes.' Claudia turned so that Cassia could watch her lips. 'That is possible, mistress. I thank you. One or more of those could have been part of the gang and brought them to the fountain, plotting the way both there and back.'

'The grounds of the Villa Carina,' Leartus continued, 'are most spacious. Its curtain wall is screened by a thick line of trees and dense bushes. Further in,' Leartus watched Cassia's hands move quickly, 'there are orchards, vine trellises…'

Claudia nodded in agreement. 'Tell me,' she spoke directly to Leartus, 'how long have you known your mistress? Since your arrival in Rome?' She ignored Urbana's quick hiss of disapproval at the abrupt change in conversation. She wanted to shift attention from Theodore, whose lower lip was beginning to tremble,- clearly the actor was now terrified of being accused of involvement in Antonia's abduction. Leartus seemed to understand. He glanced quickly at Cassia, who nodded.

'I have known my mistress,' Leartus moved his head from side to side, 'for some fifteen years. We were taught this sign language by one of her…' he paused in embarrassment, but Cassia nodded, 'by one of my mistress' former patrons, before she accepted the love of the Lord Christ.'

'Are you a follower of the Way?' Claudia used Presbyter Sylvester's term for his religion.

'Oh yes!' Leartus agreed. 'I have been baptised and received the imposition of hands. I am allowed to participate in the Agape.'

'Ah yes.' Claudia smiled understandingly. The Agape lay at the heart of the Christian faith: their belief that bread and wine could be transformed into the Body of the Risen Christ.

'Theology,' Urbana's voice turned waspish, 'might solve this, but God needs a helping hand. Your Excellency,' she continued brusquely, 'I am most pleased that Murranus can join us, his courage and skill are legendary, but what about the future, the past? These vile creatures who have-'

'They'll be caught,' Helena snapped. 'They will be caught.'

Urbana gestured deprecatingly at Claudia.

'Don't!' Helena drew herself up. 'I am the mother of the Emperor of Rome. My word is law. Those responsible for these heinous deeds will die by crucifixion or in the amphitheatre. Have more trust in Claudia.' She looked at her protegee, who sat, hands in her lap. Claudia was used to such insults and always vowed never to react or allow herself to be drawn in.

'Nothing,' Helena whispered, 'is what it appears in this city.' She leaned over and patted Claudia gently on the shoulder. 'A slingshot is small but it can still bring down a giant!'

Urbana shrugged as if grudgingly accepting this. Helena softly clapped her hands, a sign that the audience was over. Everyone except Claudia was told to withdraw and wait in the antechamber. Urbana glanced haughtily down her nose at Claudia; Cassia winked and fluttered her fingers. They all left, Theodore languidly protesting how his stomach was delicate and how at the She Asses he would have to be most careful what he ate and drank.

Helena waited until the door closed behind them, Burrus standing guard against it. Then she eased off her sandals and went and stood on the balcony overlooking the gardens. She beckoned Claudia to join her and put an arm around her, drawing her close.

'Christians,' she laughed softly, 'I love them dearly but they can act so superior. They should study their scriptures more closely and exercise humility. Urbana is powerful. Who knows how she got old Aurelian so firmly under her thumb. In two days' time,' she drew Claudia closer, 'Antonia will be released. There will be no soldiers or Vigiles, but I want you, Claudia, like the mouse you are, scurrying around that cemetery to see what you can find.' She hugged Claudia tightly. 'Do that,' she whispered, 'hunt these kidnappers down, and I'll make sure Murranus becomes too fat and wealthy,' she relaxed her grip, 'to bother about the arena.'
