We rode up as quietly as possible. We all dismounted. With drawn swords, Justinus and I went straight to the hovel where Pius and his wife lived, while our slaves checked around the back. We banged the door, but there was no answer. The hutment which belonged to Nobilis looked as deserted as before. While we continued knocking, a man appeared in the doorway of the third hut. A woman’s voice sounded behind him.

‘What’s that noise?’ he shouted. It was the other ‘Melitan’. I recognised him, and he recognised me—though he cannot have known quite how familiar he seemed. Anacrites had said the twins were not identical; maybe this one was half a digit taller, a few pounds heavier, but there was little in it.

‘Claudius Pius?’ If so, he was on the wrong doorstep, growling over his shoulder at the wrong woman. Mind you, it did not surprise me that one of the Claudii should be screwing his brother’s wife.

He rounded aggressively. ‘No. I am Virtus.’

I believed him. We had muddled them up. I should have known. Anyone who has ever seen a theatrical farce would expect the wrong one to pop out of a doorway. That’s what you get with twins.

He could be lying. Impersonating each other to fool people is a lifelong game for twins. When I was at school, the Masti were famous for it; their loving mother helped by always dressing them in identical tunics, with their hair curled in the same ridiculous quiff. They spent their days tormenting our teacher, then later were reputed to swap girlfriends. Causing confusion would have gone on for ever, if Lucius Mastus had not been run over by a stonemason’s wagon. His brother Gaius was never the same afterwards. All the joy went out of him.

Virtus had the same build, skin, freckles, light eyes and upturned nose as the man Petro and I had captured. I felt uncomfortable with it, though I did not believe the telepathy of twins could have told him what his brother went through. I suppose I had a bad conscience.

After grumbling noises from indoors, Byrta sidled into view next to him. In the act of re-draping her clothes, she hitched a scarf around her neck. Maybe it was to hide love bites, if she called their relationship love. It was some rich red colour, decent material. I supposed Virtus must have brought it for her from Rome as a present.

She vouched for him being Virtus not Pius. I said he had to come with us. He reluctantly complied. His wife did not rush to pack him a travelling bag. We searched his home before we left, but found nothing, not even weapons. If he really was Virtus, he had left his armoury in the Transtiberina apartment, so it was now secured at the Fourth Cohort’s station house. The woman stayed behind with their children.
