‘I’ll be fine, you’ll see. It’s him you need to look out for. Cato.’

‘No!’ Septimus thrust up his hand. ‘Only use your cover names from now on. At all times. Whoever you were before today must be left behind. From now on it’s Capito and Calidus.’ He stared at them a moment and then made towards the door. ‘Get some sleep. Tomorrow you join the Praetorian Guard.’

CHAPTER FIVE

Early the next morning Macro and Cato passed through the Viminal Gate on the city wall and into the suburb where the Praetorian camp had been constructed during the reign of Tiberius. A light rain was falling and formed puddles in the expanse of the parade ground that stretched from the city wall to the camp. They strode across the open space to the main gate and presented themselves to the optio on watch in the guardhouse. He was a short, well-built man with neatly trimmed hair that had receded some way. Macro and Cato had lowered their yokes and stood to attention as the rain dripped from the hems of their cloaks.

‘What do we have here then?’ the optio asked good-naturedly.

Cato reached into his side bag, drew out the document appointing them to the Praetorian Guard and handed it to the optio. ‘Transfer from the Second Legion, sir. Legionaries Titus Ovidius Capito and Vibius Gallus Calidus. We’ve been appointed to the Guard.’

‘Oh really? Capito and Calidus? Sounds like a bloody mime double act.’ The optio took the flattened scroll and unravelled it. He quickly scanned the document and looked up. ‘It says here, “For meritorious conduct in the field”. Did you two take on the barbarian army by yourselves then?’

Cato felt a fleeting desire to tear a strip off the optio, but suppressed the impulse. They were back in the ranks and needed to behave accordingly.

‘No. Optio.’

‘No? Then I’d like to know what you two heroes did that warrants a transfer to the Praetorian Guard. But that’ll have to wait.’ He looked round them and pointed to one of the men standing by the gate. ‘Over here!’

The Praetorian came trotting up and stood to attention. Cato glanced at him. He was young, barely out of his teens. Like the Praetorians who had briefly appeared during the early stages of the campaign in Britannia, he wore an off-white tunic and cape. Beneath the cape glinted a vest of scale armour of the same issue that some legionaries still favoured. The rest of his kit - sword, dagger, boots, groin guard and helmet - were standard issue. Only the shield was different, oval rather than the rectangular design used in the legions. A large scorpion decorated the front. The symbol had been chosen by a previous prefect, Sejanus, to flatter his master, Emperor Tiberius, who was born under that star sign.
