The sound of hooves drumming across the parched ground drew their gaze towards the arched entrance and a moment later the dark silhouettes of mounted men filled the gate as they swiftly reined in and walked their horses inside. There were four of them, swathed in dark robes and turbans with veils that covered all but their dark eyes. For an instant all was still, and just the heavy bellows breath of the horses and the stamping of their hooves echoed round the station. Then, as his eyes adjusted to the gloom, the leader of the horsemen plucked his veil aside and smiled at Macro.

‘Symeon!’ Macro grinned back. ‘Good to see you. Is everything ready?’

‘Yes, Prefect.’ Symeon slid down from his saddle and gestured to his followers to do the same. ‘All is ready.The caravan is just behind us. It did not take me very long to find a cartel willing to have their revenge on these desert raiders.’

‘Good.’ Macro was relieved. His plan had hinged on Symeon’s persuading some Nabataeans to turn on their tormentors of the last few months. Now all the elements had fallen into place and the trap was ready to be sprung.

Symeon stood aside and gestured to the men with him. They had also lifted their veils and Macro saw two older men, perhaps the same age as Symeon, but darker-skinned. Symeon gestured to them. ‘Tabor and Adul, my former business partners. Tabor also represents the cartel that owns this caravan. He and Adul still provide escorts for caravans from Arabia up to Petra. They’re travelling with the caravan because they want to extend their escort business towards Syria. Frankly, I suspect they’ve just come for the fight.’ Symeon grinned, and then placed his hand on the shoulder of the last man, who was younger. He was shorter than Symeon, though powerfully built with fierce black eyes and a neatly trimmed moustache. Symeon gazed at him proudly. ‘This is Murad, my adopted son. He took over my share of the business when I returned to Judaea. Tough as they come.’

He spoke to the young man in Aramaic and Murad grinned, revealing fine white teeth. He drew his finger across his throat and made a guttural hiss to emphasise the gesture.

‘I think I might just get on well with you, young Murad.’ Macro smiled back, then bowed his head in greeting to Symeon’s companions.’Did you bring spare robes?’

‘Of course, Centurion. They’re on the lead camels.’

Macro clapped him on the shoulder. ‘Fine work! Now, all that remains is to give those raiders the surprise of their lives.’
