Helena and I exchanged a surreptitious glance. We had forgotten this one. He had been in Petra and ought to have been included in our list of suspects. Something told us that being forgotten was his permanent role. Being constantly overlooked could give him a motive for anything. But maybe he accepted it. So often it is the people who have who think they deserve more. Those who lack expect nothing else from life.
Such was our visitor – a miserable specimen. He had appeared around a corner of our tent very quietly. He could have been lurking about for ages. I wondered how much he had overheard.
'Hello there! Come and join us. Didn't Chremes mention to me that your name is Congrio?'
Congrio had a light skin covered with freckles, thin straight hair, and a fearful look. He had never been tall to begin with, and his slight, weedy body stooped under burdens of inadequacy. Everything about him spoke of leading a poor life. If he was not a slave now he probably had been at some stage, and whatever existence he snatched for himself these days could not be much better. Being a menial among people who have no regular income is worse than captivity on a rich landowner's farm. No one here cared whether Congrio ate or starved; he was nobody's asset, so nobody's loss if he suffered.
He shuffled near, the kind of mournful maggot who makes you feel crass if you ignore him or patronising if you try to be sociable.
'You chalk up the advertisements, don't you? I'm Falco, the new jobbing playwright. I'm looking out for people who can read and write in case I need help with my adaptations.'. 'I can't write,' Congrio told me abruptly. 'Chremes gives me a wax tablet; I just copy it.'
'Do you act in the plays?'
'No. But I can dream!' he added defiantly, apparently not without a sense of self-mockery.
Helena smiled at him. 'What can we do for you?'
'Grumio and Tranio have come back from the city with a wineskin. They told me to ask whether you wanted to join them.' He was addressing me.
I was ready for bed, but put on my interested face. 'Sounds as if a sociable evening could be had here?'
'Only if you want to keep the caravanserai awake all night and feel like death tomorrow,' Congrio advised frankly.
Helena shot me a look that said she wondered how the town-and-country twins could tell so easily who was the degenerate in our party. But I did not need her permission -or at least not when this offered a good excuse to ask questions about Heliodorus – so off I went to disgrace myself. Musa stayed with Helena. I had never bothered to ask him, but I deduced that our Nabataean shadow was no drinking man.
Congrio seemed to be heading the same way as me, but then turned off on his own. 'Don't you want a drink?' I called after him.
'Not with that pair!' he responded, vanishing behind a waggon.
On the surface he spoke like a man who had better taste in friends, but I noticed a violent undertone. The easy explanation was that they pushed him around. But there could be more to it. I would have to scrutinise this bill-poster.
Feeling thoughtful, I made my own way to the Twins' tent.
