‘There’s a world of difference between offering advice and the insolent, insubordinate comments you have grown accustomed to. That comes to an end now.’ Cato spoke softly through gritted teeth, his face no more than a foot away from the Thracian’s. Despite his earlier intention to play his hand carefully, something had snapped inside him and a cold, ruthless anger flowed through his veins. ‘I have seen all I need to see of the fort, the men, the officers and the way you have been waging your campaign against the enemy. This is not the way of Rome. This is not the way of the Roman army. This is not my way. I am in command here and my orders will be obeyed without question from now on. If you overstep the mark again, Centurion Quertus, I will have you arrested and charges brought. Do you understand?’

The Thracian put his hands on his hips. ‘Finally . . . I wondered how long it would be before it came to this. I was starting to doubt that you had any backbone at all. Just like that fool, Prefect Albius. Now, I’ll have my say. I know your type. Young men who have caught the eye of a legate or governor and been promoted far beyond what they deserve. I was a fighting man while you were still sucking at your mother’s tit. Sure, you’ve had your share of campaigns and battles, but you, and all the other stuck-up Roman officers, have been fighting to subdue Britannia for nearly ten years now. And the enemy are still out there, laughing at you.’ He leaned closer and slapped his chest. ‘They mock you but they fear me. I know how to break their will to fight. Your methods have failed. Mine are succeeding. And you’d do well to keep your nose out of it and leave the command of the garrison to me . . . sir.’ He uttered the last word with undisguised irony and contempt.

Cato stared levelly back at him. ‘Your methods? I don’t see any method to what you have done here. The heads on pikes, the impaled bodies, the burned villages, the slaughtered women and children. There is no method in that. Just the bloodthirsty cruelty of a barbarian.’

‘A barbarian who knows his enemy as intimately as his own men.’

‘Oh?’

Quertus was quiet for a moment before he continued in a flat tone. ‘You think me a barbarian . . . well, I learned my ways at the hands of the enemy. The enemy are a cruel people. Cruelty is the only language they understand, so I resolved to pay them back in kind, and with interest. And now it is their will that is breaking. I know what I am doing, Prefect. And I can do it with or without you. Understand that and perhaps you’ll survive to return to Rome one day.’
