The party of horsemen headed towards the rising ground. A dusty track lay ahead and Ajax took this as a good sign. All tracks led somewhere and there was a good chance that there was a route out of the defile. Looking back over his shoulder he saw that the closer of the two enemy squadrons was no more than a third of a mile behind them, closer than it had been a moment earlier, he calculated grimly. The track wound up into the rocky ground and the sounds of hoofbeats echoed off the parched stone. Soon the bends in the route hid their pursuers from view and Ajax wondered if there might be a chance to branch off the track and lose them. However, there proved to be little opportunity for such a ruse as the only paths leading away were too narrow and steep for the horses.

Then, just over a mile into what had become a gorge, the track widened out into an open space, surrounded by towering cliffs and jumbles of boulders. Here and there Ajax could see small openings in the rock, like caves. The track seemed to end abruptly at the foot of a tall cliff. There was no sign of life. Nothing moved about them and a profound sense of stillness and foreboding seemed to fill the hot air trapped in the large natural arena.

‘What is this place?’ asked Karim. ‘Those caves, they’re not natural. Someone has cut them out of the rock. Look there.’

He pointed towards a larger entrance, half hidden behind a giant boulder. The shaded interior was framed by square-cut masonry, which was covered with small carved symbols, like the ones Ajax had seen cut into the temple. He edged his horse closer and peered into the tunnel. The walls had been painted and they stretched off into the shadows, out of sight. Before he could examine the cave any further, one of his men called out and pointed back down the track. Ajax and his party strained their ears and then they heard it, the clattering echo of hoofbeats.

‘Karim! Take the archers and get up on that cliff!’ He indicated a jumble of rocks that formed the last bend in the track. ‘Wait until they draw level with you before you shoot.’

Karim nodded and hurriedly dismounted to take command of the Arabs. Ajax faced the rest of his men, all that remained of his followers from Crete. ‘The track just beyond the cliff is narrow. We can hold it well enough. Every one of us is worth three good Romans any day, and it seems there are plenty of tombs to go round.’ He gestured at the openings in the surrounding rocks and his comrades laughed. ‘Let’s make sure we fill ’em up with dead Romans.’
