Ajax did not break his stride as he approached the Roman. At the last moment he sprang forward, lunging with his sword. The point plunged into the sentry’s torso and the man folded up with a groan. His companion was stunned into stillness for an instant, then as he began to lower his spear, Canthus parried it aside and thrust his sword into the man’s throat. He collapsed to his knees and bled out quickly before toppling aside. Ajax hurriedly finished his man off and turned towards the last sentry. He had heard something and stood on the other side of the small encampment, spear grasped in both hands. Before he could call out, a shadow sprang up from the ground behind him and there was a brief grunt as Karim brought him down. Ajax stared, poised to dash across to Karim’s aid, but then the Parthian rose and lifted his sword.

‘All done.’ Canthus breathed deeply with relief. He turned back towards the channel and let out a low whistle. At once a score of shadows emerged from the reeds and padded towards them. When they had gathered round Ajax, he gestured towards the shapes of the men sleeping but on the ground a sufficient distance from the date palms to avoid any scorpions or snakes dropping on them during the night. ‘Kill them, and kill them quietly,’ Ajax ordered. ‘Go.’

His men crept amongst the sleeping Romans, kneeling down to smother their mouths with one hand while using the other to cut their throats. Here and there a victim struggled briefly and one managed to let out a gurgling cry before being swiftly silenced. When the last of the Romans was dealt with, Ajax led his men to the horse line. The saddles were arranged neatly to one side and took little time to fit on to the horses. A short time after the killing had begun, Ajax and his men were mounted and only Canthus remained on foot.

‘You’re certain that you wish to remain behind?’ asked Ajax.

‘Yes, General.’

‘If they discover that you’re a spy, and they are bound to sooner or later, then you can expect no mercy.’

‘I shall be careful. Besides, I am enjoying the deception. I have never played a role like this before.’ Canthus’s smile faded and he nodded towards the east where the first glimmer of the coming day was rising into the haze above the Nile. ‘You’d better go.’ He reached up and clasped Ajax’s hand. ‘May Fortuna ride with you, my General.’

Ajax nodded his gratitude, then released the man’s hand, took up his reins and set his mount towards the hills to the west, intending to ride out into the wilderness, away from the Roman forces surrounding the temple. After that they would head up the Nile and find somewhere to cross the river and rejoin Prince Talmis and his army.
