Ahead, the men who had attacked the villa were sprinting across the open ground towards the safety of the treeline, abandoning their loot. Even as they raced across the snow-covered fields, Marcus could see most of them would escape well before the Roman cavalry reached the scene. Once they disappeared into the depths of the forest where the snow had not penetrated, there would be no tracks to follow and they could escape. Marcus felt relieved by that.

The last of the rebels had already vanished from sight as Caesar savagely reined in outside the villa. Behind him, the rest of his men caught up and the air was filled with the snorting of horses and chink of bits.

‘Decurion!’ Caesar thrust his hand towards the first officer to arrive on the scene. ‘Take your squadron and go after them. On foot if necessary.’

‘Yes, sir!’ The decurion snapped a salute and bellowed to his men to follow him as he galloped across to the line of trees f stretching along the edge of the valley. Briefly, Caesar turned to look at the villa before dismounting and handing his reins to one of the bodyguards. Festus and Marcus followed suit and joined him inside the wall.

The fire had taken hold of the main building and already tongues of flame were stabbing up into the air between the roof tiles. A large section of the roof gave way and crashed into the blaze with an explosion of sparks that swirled high into the air. One of the adjoining buildings was already alight as the fire spread.

Caesar raised an arm to shield his face from the heat. ‘Look for survivors! I’ll check this side of the villa. Festus, take Marcus and search the other side!’

Festus pulled Marcus towards the side of the building, where the double doors of a long shed stood open. While Festus strode ahead, Marcus struggled to keep up. As they reached the end of the shed, a wiry man with grey hair lurched into view. A club swung from one arm, and a small chest was tucked under the other. With astonishing speed, he raised his club and slashed at Festus’s head. The glancing blow threw Festus into the snow at his feet with a deep groan. At once the man raised the club again, ready to strike at his head.
