They plumped down on stools in their shop, heavy-hearted. Men are so easily deflated by a bad experience. I stayed on my feet, arms folded, anxious to knock their knowledge out of them while they were emotionally low. As I had said to Dromo, it helps to stay occupied. I was not drained in the same way as them; after what happened to Myla, I felt bitterly businesslike.

‘Don’t think I missed this. Earlier today, Myrinus, you let slip something significant. When Graecina and Myla had their fight indoors this morning, you said you heard it from the back of your premises. So you can hear anything noisy that goes on in the Aviola apartment?’

They looked shamefaced. On an earlier occasion they had said it was impossible. I told them if they answered honestly now there were unlikely to be consequences. They must have heard that kind of lie before, but they could see there was no escape. ‘It’s me or the vigiles – and the vigiles will not ask you nicely!’

They came clean. Their mezzanine sleeping ledge was in a half-way, half-height nook at the back, which they went into via a short ladder; through a poorly-built wall Secundus and Myrinus could hear quarrels, fights, dogs barking and music – any loud or sharp noises. They were not bothered by events in daily life. Normal sounds went on like all the background hum of Rome: the cries, creaks, bells, barks, crowing, mooing, whistling, laughter, singing, hammering, barracks trumpets, mystical incantation and sexual moans that we all lived with on a daily and nightly basis. But they would take note of any real excitement from inside the apartment.

‘I have been told there was quite a lot of that!’ I commented. I felt sour. I liked this pair and was sorry they misled me earlier.

On the night of Aviola and Mucia’s dinner party, after the guests left, Secundus and Myrinus had sat in their shop with their friend Libycus. He was saying goodbye. He knew he was either going to Campania the next day with his master – or else he was listed to be sold at the slave market.

‘He thought that was a possibility?’ The two leatherworkers nodded. ‘Really? I thought Libycus had been with his master for years, worked intimately with him, and was so much trusted he is due to be freed under Aviola’s will?’
