Above the gate Cato noticed that Macro was gripping the pommel of his sword so tightly that his knuckles were white and the tendons leading back towards the wrist stood out like iron nails under the skin. Cato felt more sick than enraged. The spectacle had made him want to throw up, and the roast pork and fine bread he had been enjoying so much only moments earlier now churned in his stomach.

‘Bastard,’ Macro whispered through clenched teeth. ‘Bastard . . . Bastard . . . BASTARD!’

His shout of rage carried down the street, and Tincommius smiled as Macro let his anger spill out.

‘Fucking bastard! I’ll kill you. I swear it! I’ll kill you!’

‘Centurion, you’re welcome to come out here and try it. I dare you!’

‘Sir,’ Cato placed his hand on Macro’s shoulder, ‘You mustn’t . . .’

Macro glanced round angrily. ‘Of course not! Think I’m stupid?’

‘No . . . just angry, sir. Angry and helpless.’ Cato nodded at the other men who crowded the palisade, staring down the street with expressions of horror and rage. ‘We all are.’

Macro turned to look in the direction Cato had indicated and saw that not only had all the remaining legionaries clambered up on to the palisade, but also the Wolves and some of Verica’s bodyguards. He swept Cato’s hand from his shoulder and roared at the men.

‘What the bloody hell do you think this is? A fucking freak show? Get off the wall and get back to your positions! Want them to just bloody hop over the wall while you’re gawping at that twat? The only men I want up here are the sentries. Move!’

The legionaries backed away from the palisade with guilty expressions and clambered back down into the enclosure, followed by the Wolves, who had no need of Cato’s shouted translation. Macro glowered at them for a moment and then turned back towards Tincommius.

When he saw that he had the centurion’s attention again Tincommius called out, ‘Macro, will you surrender? Answer me!’

The centurion stood still and silent, lips compressed into a tight line on his weathered face. A terrible despair gnawed at his guts and a fathomless anger and hatred for Tincommius filled his soul as Macro watched helplessly.

‘Very well. The next man, then.’ Tincommius beckoned for the second prisoner to be brought forward.
