‘No. Just straightforward politics.’

‘But how would Longinus have got in touch with Bannus?’

‘He must have some kind of intermediary. A dangerous job to be sure, but at the right price I’m sure Longinus could have found someone to approach Bannus and make him aware of the Governor’s offer not to intervene. All that would remain to be done would be to provoke the locals into rebellion, and Scrofa and Postumus have been doing their best to fan the flames of discontent.’

‘Fan the flames of discontent?’ Macro smiled. ‘You’ve not been writing poetry on the sly, have you?’

‘Just a figure of speech. Be serious, Macro.’ Cato concentrated again before continuing. ‘The thing is, I’m not sure that Longinus is fully aware of what he is unleashing. It seems that Bannus has also been in contact with the Parthians. So far I imagine they’ve promised him some weapons for his men. Of course, they’d never own up to it. Anything they can do to undermine Roman power in the east is all part of the great game as far as they are concerned. However, if they got wind of an arrangement between Bannus and Longinus then they’d instantly see the chance to settle the score with Rome once and for all.The moment Longinus leaves Syria with the eastern legions at his back, Parthia would have a free hand in the region. If they moved quickly enough they could overrun Syria, Armenia, Judaea, Nabataea, and maybe even Egypt.’ Cato’s eyes widened as the implications of what he had said hit home. ‘Egypt! If they took that then they’d have a stranglehold on the grain that feeds Rome.They could force peace on Rome on almost any terms they wanted.’

‘Hold on there!’ Macro raised his hand. ‘You’re jumping at shadows. Remember, Cato, you’re just outlining possibilities.’ He smiled. ‘There’s still a long way to go before the situation represents any serious threat to Rome.’

Cato couldn’t help smiling at the way his thoughts had run away with him. Nevertheless, there was a great deal at stake, and not much time to try to do something about it. Until confirmation of Macro’s command of the Second Illyrian came through there was little action that the two officers could take except observing events as they unfolded. ‘All right then, I’ll keep my mind focused on the here and now.’

‘For the moment, that would be best.’

Cato nodded, and then reached for a spare linen tunic and pulled it over his head. ‘What about you? How did your patrol go with Postumus?’
