She was in her twenties, plain-faced with a snub nose, loose, flyaway hair and a faint sour smell as if somebody spilled milk on her several days ago. She wore a drab brown dress with one sleeve rolled and one to the cuff. It wasn’t a fashion statement. She was too lazy to notice it. Her girdle was a rope that would have doubled as a bullock halter. She wore no jewellery. I guessed she had never worked, so had no money herself, and the men she chose were never generous.

It was all a waste of time, of course. Demetria admitted she still lived with Costus, pretty well in hiding. He had dragged her along tonight to see us hoping there would be money in it. She might have had enough spirit to run away from Nobilis, but on the whole Demetria’s instincts were to do as she was told.

She would not talk about her marriage to Nobilis. She did not accuse him of violence against her, nor of battering her lover. Whatever pressures to keep quiet had been embedded in her by Claudius Nobilis, they were still firmly in place.

She had no idea what Nobilis got up to nowadays or where he had gone off to; she had no contact with the family—though when I said I had spoken to the other two women, she asked after Plotia and Byrta. She swore she knew nothing about what happened with Modestus and Primilla and since she hadn’t lived with Nobilis then, it seemed reasonable. When I asked if she had ever had reason to suspect visitors were vanishing at the compound, she denied it.

‘So why did you come to find me?’ I demanded in exasperation.

That was when she came straight out and said Costus wanted her to beg for money. I could hardly complain. As Helena sniggered afterwards, offering facts for a cash reward was what I did as an informer.

I replied that when I made the offer, facts did exist.

There was one outcome. I asked Costus if he had been there when the man from Rome that Thamyris mentioned had turned up. According to Costus, it was a couple of days before. The description he gave of peculiar eyes, greased hair and smooth-talking sounded suspiciously familiar; it could almost be Anacrites himself.

‘Did you hear what was said?’

‘He took Thamyris out of earshot.’

‘So you’ve no idea what he wanted?’

‘Oh yes!’ Costus seemed surprised anyone should think his employer would keep a city man’s secret. ‘He ordered the boss that if anyone came asking about Nobilis or the other Claudii, he was to say nothing.’

‘Did he reinforce that order?’
