Metellus was still laughing. ‘That’s priceless, that is! And what punishment would you have me do, sir? Empty the latrines? Pull an extra guard duty on the main gate?’ He waved a hand at the clearing. ‘Look around you. There’s no camp here. No ramparts to defend. No barracks to clean. No latrine to empty . . . nothing. Nothing left for you to command. Except us. Face up to it, boy.’

Cato shifted his grip on the spear shaft and spun it round, so that its point hovered no more than a foot away from the legionary’s throat. Around him the others stopped eating and reached for the handles to their knives and swords, watching the centurion intently.

For a moment everyone was still, muscles tensed and hearts pounding as the sow continued her high-pitched shrieking from the side of the clearing.

Then Figulus slowly stepped forward and gently pushed the tip of Cato’s spear down. ‘I’ll deal with this piece of shit, sir.’

Cato glanced towards him, brows clenched together, and then he lowered his spear as he looked back at Metellus, and spat on the ground beside the legionary.’All right then, Optio. He’s yours. See to it at once.’

As soon as he had uttered the words Cato turned away, in case the glimmer of tears at the corner of his eyes betrayed his strained emotions. He strode off to the side of the clearing and made his way to a small grassy mound that looked out across the marsh.

Behind him Figulus hauled Metellus to his feet. ‘Time to teach you a lesson, I think.’

The optio pulled his sword out of his waistband and tossed it to one side, and raised his fists. Metellus eyed him warily and then smiled. The optio was tall and broad, typical traits of the Celtic blood that flowed through him. Metellus was leaner, but had been ruthlessly hardened by the years he had served with the Eagles. The contest would pit brawn against experience, and Figulus could see that Metellus fancied his chances as he lowered his body into a crouch and waved the optio towards him.

Metellus took a pace forwards and with a wild roar the legionary launched himself into the attack. He never made it. Figulus threw his right fist forward in a blur and there was a soft crunch as it slammed into the legionary’s face. Metellus dropped heavily to the ground, motionless, knocked out in one blow. Figulus delivered a swift kick to the prone figure, then rounded on the other legionaries.

He smiled, and said softly, ‘Anyone else here want to fuck with authority?’
