'I do believe you,' Claudia conceded. 'I think you are telling the truth, but not all of it. Something happened along that wall, something that has come back to haunt you all, but why now, eighteen years later?'

She studied Crispus carefully. He was younger than the rest, and she noticed the small bead of sweat running down from beneath his close-cropped hair.

'What are you frightened of, Crispus?'

'The past,' he mumbled, and stared up at the smoke-blackened ceiling. 'Always the past! You don't know what it was like out there, desolate, empty, nothing but the grass bending under the wind, the lonely call of birds, the cry of animals at night and, when the civil war raged in the south, the wall being stripped. We had this nightmare, or at least I did, that the Picts would stream across the wall and surround us, cut us off, take us prisoner. If we fell into their hands…' He stared at them and blinked. 'If you fell into the hands of the Picts, they'd take weeks over killing you. I've seen their work: men nailed to trees, prisoners slowly tortured…' He wetted his lips, turning his head as if straining for a sound, then muttered something.

'What was that?' Murranus asked. He got to his feet, went closer to the veteran and sat down. 'What is it, Crispus? I have not been a soldier but I know what it's like to fight, to be wounded. What is it you're hiding?'

Crispus opened his mouth to reply but shut it when he heard a sound on the stairs.

'You can't answer, can you?' Claudia asked.

Crispus closed his eyes and shook his head.

'I daren't,' he whispered. 'It had nothing to do with me.'

'You were at General Aurelian's party,' Claudia continued. 'What happened?'

Crispus, relieved at the change in questioning, shrugged and swallowed hard.

'You know the General, or perhaps you don't,' he replied. 'Generous, a great man, a good leader, he looked after his troops. Well, over the years he invited all those who'd served with him to a banquet in his garden. They were marvellous occasions, beautiful lanterns hanging from the trees, serving girls, ladies of the night, musicians, actors, tumblers. This year it was our turn. None of us wanted to miss such an exciting evening. We gathered just before dusk and the celebrations went on well into the next day. The General is a hospitable man; those who wanted to could sleep in the gardens, and when they woke up to quench their thirst, there was more food and wine.'

'Did you see anyone,' Claudia persisted, 'or anything which reminded you of the past?'

Crispus closed his eyes, thinking hard.

'Anything at all,' Murranus insisted. 'Anything untoward.'

Crispus opened his eyes. 'I swear,' he pointed to the Lares on the table, 'I swear by that. I saw nothing, I heard nothing.'

'And the rest?' Murranus asked. 'Stathylus, Lucius, Petilius, Secundus?'

'Petilius may have.' Crispus paused to recollect his thoughts. Tm not too sure what he wanted to see General Aurelian about. We presumed it was something that happened at the party, because it was only after he saw him that he began his petitioning. It could have been something else. As for the rest of us,' he shook his head, 'nothing untoward was noticed, nothing at all.'

'Nothing what?'

Claudia looked round. Secundus, a platter of bread and cheese in one hand, his other resting against the doorpost, was staring threateningly across.

'What's going on here?' Secundus strolled across and slammed the platter down on to the table. 'If you've got any questions, wait for our officer to return.'

Murranus got to his feet and squared up to him.

'Do you want to die, Secundus?' he asked quietly. The veteran blinked. 'Do you want to die?' Murranus pushed his face closer. 'Because I'll tell you this, someone in Rome is killing former members of your cavalry troop. Your friends are dying in a barbaric way. How do you know you won't be next? I don't think we've been told the truth.' He gestured at Claudia. 'She is the Empress' representative. If you want, we will invite you back to the palace and we can continue our conversation there.'

'We've done nothing wrong!' Secundus blustered. 'You can't arrest us.'

Murranus seized the man's face between his hands. Secundus had the sense not to resist. 'Listen, you fool,' Murranus whispered hoarsely, 'we are not arresting you, only trying to protect you.'

'Where's Stathylus?' Crispus half rose. 'I thought he'd gone out to relieve himself. He should be back by now.'

Murranus took away his hands. Secundus walked to the table, drew the dagger from his waistband, cut himself a piece of bread and cheese and started chewing noisily. Claudia was about to return to her questioning when she heard a cry from below. She hurried to the door and stared down the wooden stairs. The tavern-keeper stood listening to a grimy-faced maid who was hysterically pointing to the half-open door. Claudia hastened down, followed by Murranus and the rest. The girl, gibbering with fright, led them out of the tavern and down to a small alleyway, a needle-thin passageway running between the houses. The tavern-keeper carried a lantern. At first Claudia thought the girl was pointing to a bundle of rubbish, old clothes -until the tavern-keeper placed the lantern on the ground. The light within strengthened, and the tavern-keeper swung away, one hand to his mouth.

Claudia slowly approached. She lifted the lantern and peered down. Stathylus lay wedged almost in the corner of the wall and the dirty rutted trackway, head tilted, his throat like a bloody gaping mouth, a terrible gash along his belly, his right hand thrown back holding what looked liked a piece of severed bloody meat. Claudia felt her gorge rise and hastily retreated. She leaned against the wall trying to control her stomach, half listening to the others' exclamations, the girl still whimpering, the tavern-keeper retching.

It was Murranus who imposed order. He returned to the tavern and came back carrying a large piece of sacking, shouting at Secundus and Crispus to help. Stathylus was lifted on to the piece of sacking, which was wrapped tightly about him, and taken across the tavern yard to an outhouse, where he was placed on an old trestle table. Lamps were brought. Claudia went out with the rest to study the corpse, but it was too much, the look of terror on Stathylus' face, those awful wounds to the throat and the belly, the great bloody mess between his legs. She could take no more and, hand to her mouth, hastened back to the tavern and its upper room. She sat for a while shivering. The lights before the Lares were now burning low; one was guttering. She stared at that bronze statue, the sinister helmeted figure, cloak billowing around the rearing horse.

'Now,' she muttered to herself, 'now they'll believe me.'

Chapter 4

Hoc volo, sic iubeo: sit pro ratione voluntas.

I will do this deed, so I order it done. Let my will stand for my reason.

Juvenal, Satires

Claudia hastily refilled her goblet of wine and drank it a little faster than she'd intended, half listening to the sounds from downstairs. She peered at the statue and recalled Murranus' question at the Temple of Hathor. If the truth be known, she believed in no religion. She could accept there might be a God, but all this bloodshed and horrid death, the sheer cheapness and brutality of life, how could Presbyter Sylvester explain all that? Noises on the stairs alerted her. Murranus, Secundus and Crispus came into the chamber, followed by the tavern-keeper bringing what he said was his best wine, along with four clean cups. He put the tray down and hastily retreated. Murranus filled the cups and raised his in the direction of the Lares.

'May his God look after him,' he toasted. 'May Stathylus be brought to a place of light. He deserved a better death.' He drank and refilled his goblet.
