'Be my guest.' Longinus leaned back in the chair as Macro strode over, lifted the lid of the chest and took out the leather case in which the scroll had been replaced to protect it. He flipped the lid back and extracted the document and then placed it on the desk in front of Longinus. The Governor casually picked up the parchment, unrolled it and scanned the contents. Then he placed it back on the table.

'Well, Centurion Macro, and Centurion Cato, your credentials are impeccable. The document appears to be authentic, in which case you are fully within your rights to act as you did.'

Postumus, who had been watching with a faintly smug expression, started at this, and pushed himself away from the window frame.

'Sir, I protest! You are the Governor of Syria, appointed by the Emperor himself. They have flagrantly defied the authority of your office!'

Longinus tapped his finger on the scroll.'By the terms of this document their authority supersedes mine. Therefore they have acted lawfully, and I'd be obliged if you'd shut up and wait until you are addressed from now on, Centurion Postumus.'

Postumus opened his mouth to protest, thought better of it and closed it. He nodded and stepped back awkwardly towards the window frame.

'That's better.' Longinus smiled. 'Now then, Centurions Macro and Cato, this is something of an unusual situation. It is not customary for officers of your rank to pop up in a far-flung province with the Emperor's permission to act as you please tucked up your sleeve. So, I'd be grateful if you could explain what is going on here.'

Macro turned to Cato and cocked an eyebrow. It was an awkward situation.They had been sent from Rome to quietly investigate the Governor of Syria and their mission had been dogged by bad luck from the moment they had entered Jerusalem. If only Macro had not lost his original letter of appointment then this present situation could have been avoided. Instead, they had been forced to use the Imperial Secretary's document and thereby reveal that they were acting directly on Emperor Claudius' authority. Cato realised that there was nothing to be gained by denying the truth.

'Sir,' he said softly to Macro,'I think we'd better come clean.'

'What?' Macro shrank from the suggestion. How the hell could he just come straight out and tell one of Rome's most senior officials that the Emperor suspected him of treason? 'Are you mad?'

'Centurion Macro,' Longinus interrupted, then feigned a look of embarrassment. 'I do beg your pardon. Prefect. I think it would be best if we spoke openly. There's nothing to hide any more. I think you should begin by explaining exactly what you are doing here in Judaea.'

Macro swallowed. 'All right then, sir. Since you want it straight. Narcissus had obtained information that you were planning to provoke a revolt in the east in order to gain reinforcements for your army.The same source then said you were intending to use your enlarged army to depose the Emperor and claim the purple for yourself.'

There was a long silence before Longinus produced an amused expression. 'What an astonishing notion. I rather think someone must have been playing a joke on our friend Narcissus.'

'Then he's not seeing the funny side of it, sir. That's why we were sent out here. To see if that's what you are planning to do.'

'And what is your conclusion?'

Macro cleared his throat. He had not felt so nervous in a long time. 'From what we've seen so far, I'd say that your conduct would seem to support the accusations being made against you.'

'Would you now?' Longinus responded tonelessly. 'If that's what you think, then you'd better be able to justify your conclusions. Because if you can't then you're going to make Narcissus look a fool. In that case I would not like to be in your boots. So what evidence have you got against me, Macro?' Before Macro could respond Longinus held up his hand to silence him, and continued. 'Let me tell you what you have got. Nothing. Nothing more than suspicion and coincidence.There are no documents to back up your version of events. And no witnesses.'

'No?' Macro smiled.'What about Postumus there? I'm sure that Narcissus has men who are more than capable of getting information out of him.'

'Assuming he was still around to be interrogated.' Longinus smiled back, and then glanced towards Postumus. 'I mean, of course, that he might flee, or go into hiding before he could be questioned.'

'I'm sure that's what you meant,' said Macro.'After all, you wouldn't want to dispose of such a loyal servant.'

'Quite. So where does that leave us?'

There was another silence as Macro pondered the question. There was no firm evidence against the Governor and everyone in the room knew it. Just as they knew it was clear that he had been plotting against the Emperor. It was Cato who spoke first.

'What if we accept for the moment that Narcissus cannot move against you?'

Longinus raised his eyebrows. 'What if we do?'

'The very fact that we were sent out to investigate the situation means that he must have some grounds for suspecting you, and he will be taking every precaution to ensure that he undermines any plan you might make to turn against the Emperor.'

'So?'

'So there's no chance that you will be given any reinforcements. No matter how much you present the situation as dangerous to Roman interests, Narcissus will not send you extra forces. In which case, any plot there might have been would be doomed to failure. Wouldn't you agree, sir?'

'Maybe. Assuming such a plot existed.'

'On that basis, there is still some advantage to be wrung out of the situation.'

Longinus stared at Cato, and then made an open gesture with his hands. 'Please explain yourself.'

'Yes, sir.' Cato concentrated for a moment and then spoke again. 'You already know the danger we face from Bannus. If his uprising spreads beyond this immediate area, then the whole province of Judaea could turn on Rome. What you may not know is that we have heard rumours that Parthia has offered to assist Bannus. With weapons, maybe even with men as well. If that is the case, then the stakes are even higher. Apart from having to crush the revolt in Judaea you would need to confront the Parthians and persuade them to withdraw their aid. If they had any doubts about your loyalty to the Emperor, the presence of a maverick Roman general on their borders might cause a diplomatic confrontation that Parthia might use to trigger a new war with Rome, sir.' Cato paused for an instant, worried that he had given his imagination too free a rein. 'At least it's a possibility, sir.'

'It's more than a possibility.' Longinus frowned. 'My spies have been reporting that Parthian troops have been spotted moving up the bank of the Euphrates towards Palymra. Their ambassador says they are carrying out exercises. It could be an unfortunate coincidence.'

'It could be, sir. But it would be rash not to make preparations to counter the threat.'

'If there is a threat. How could they know about Bannus' planned uprising?'

'I'm sure they have spies just as we do, sir.'

'You said there was some advantage to be gained,' Longinus reminded him.

'Yes, sir. If you send us reinforcements to help find and destroy Bannus, then the danger in Judaea can be averted. That leaves you free to confront Parthia.A strong show of force should discourage them from breaking the peace. When everything has settled back down, you can report your achievements to the Emperor and the Senate. I'd say they will regard you as something of a hero. Certainly enough to remove any doubts over your loyalty, sir.'

Longinus considered the prospect Cato had envisaged for him, and then looked at the young officer with a cool smile. 'You have a devious mind, Centurion Cato. I would hate to have you as a political opponent. Worse still, as one of Narcissus' lieutenants. Then you would truly be a man to be wary of.'
