A thick pall of smoke from the direction of the Forum billowed into the afternoon sky as the column of litters and soldiers made their way down the Viminal Hill towards the centre of the city. Even though news of the riot had spread through the streets, many people were still going about their business and hurried out of the way of Centurion Lurco and the two sections leading the party. The Germans closed ranks around the litters carrying the Emperor, the Empress and the two boys. The rest of the Sixth Century filled in the gaps between the remaining litters and brought up the rear.

Cato, Macro and fourteen other men were under the command of Tigellinus as they marched behind a litter shared by Narcissus and two other advisers, including the man Macro had seen with Agrippina. They were marching four abreast, with Fuscius to Macro’s right and a surly youth beyond him. After a quick look to make certain that the optio was facing forward, Macro spoke softly to Fuscius.

‘See the men in the litter directly ahead of us?’

‘Yes.’

‘I recognise Narcissus, but who are the others?’

‘The one opposite him, the one with the good looks, is Pallas. One of those bloody freedmen the Emperor insists on surrounding himself with. The other one’s Seneca, Nero’s tutor and adviser.’

‘I see.’ Macro glanced to his left at Cato and cocked an eyebrow before realising that it was pointless beneath his helmet. ‘Pallas, eh? I wonder what he’s up to?’

‘Up to?’ Fuscius turned his head to Macro. ‘What do you mean?’

‘Nothing.’

Before they could say another word, Tigellinus glared over his shoulder. ‘Silence in the ranks! Keep your bloody mouths shut and your eyes and ears open!’

They progressed in silence and as they drew closer to the Forum the street ahead of them began to empty. A few small groups of anxious-looking civilians hurried by, squeezing past the column with barely a comment or look of surprise as they glimpsed the imperial litter with its barbarian escort. The roar of the mob was clearly audible now, and soon they could discern distinct shouts of anger and even a shrill scream of terror. The smoke was dense and acrid. Wafts reached the column as it entered the square where Cato and Macro had been involved in the brawl a few nights earlier. Cato looked over towards the inn and saw its owner closing the shutters of a window that looked out on to the public fountain, before scurrying inside and closing the doors. A thin and frail-looking woman sat on the edge of the fountain nursing a crying infant with bulging eyes and skeletal arms. She watched the soldiers and litters passing by for a moment before struggling to her feet and limping across to them, holding her free hand out.
