'For another thing,' Marina pressed on inexorably, 'there was the little matter of him sending me off with you!'

'We don't need to resurrect that,' I said. Well, I had to try.

'Don't mind me,' smiled Helena. The knives were out all round.

'Suit yourself,' sniffed Marina. 'But Marcus, if you really want to know what he was up to that evening, I think this little incident needs considering.'

'Why?' Helena asked her, bright with unhealthy interest.

'It's obvious. It was a blatant fix. He annoyed me over the brunette, then he got up sunshine's nose as well.'

'Doing what? What offended sunshine?'

'Oh I can't remember. Just Festus being himself, probably. He could behave like a short-arsed squit.'

I said, 'Looking back, I can see he was trying to get rid of both of us-despite the fact it was our last chance of seeing him, maybe for years.'

'You were both very fond of him?'

Marina threw up her hands elegantly. 'Oh gods, yes! We were both planning to stick to him like clams. He had no chance of keeping secrets. Even getting us to leave the Virgin was not safe enough. We would both have been back. Well, I would. If I had gone home and he hadn't turned up soon afterwards, I would have stormed out again looking for him-I knew where to look, too.'

Helena glanced at me for confirmation. 'Marina's right. Festus was often elusive, but we were used to it. She had dragged him away from drinks counters in the early hours of the morning on many occasions. It was their natural way of life.'

'What about you?'

'As it was his last night, once I sobered up a bit I might well have gone back to toast his health again. I knew his haunts as well as Marina did. If he wanted any privacy, then he had to shoot us off somewhere, and make it stick.'

'So he annoyed both of you deliberately, then threw you together?'

'Obvious!' Marina said. 'Marcus had always been jealous of Festus. This loon had been eyeing me up for years-so why did Festus suddenly present him with the goods after all that time?'

I felt surly. 'I seem to be coming out of this as weak, cheap, and sly.' They both looked at me in silence. 'Well thanks!'

Marina patted my wrist. 'Oh you're all right! Anyway, he owed you enough; no one could say otherwise. What about that business with your client?'

She genuinely puzzled me with that one. 'What client?'

'The woman who hired you to find her dog.' I had forgotten the damned dog. The female client now returned to mind quite easily-and not only because she was one of the first I ever had after I set up as an informer.

'It was a British hunting hound,' I told Helena hastily. 'Very valuable. Superb pedigree and could run like the wind. The daft creature was supposed to be guarding the woman's clothes at some bathhouse; a slave stepped on his tail accidentally and he ran off like stink down the Via Flaminia. The young lady was heartbroken:' It still sounded an unlikely tale.

'Well you've been in Britain!' Helena Justina said gently. She knew how to cast aspersions. 'I expect you have a special affinity with British dogs.' Oh yes. Lovely work for a professional; every informer ought to learn how to call 'Here boy!' in at least twelve languages. Five years later the jobs I was taking on seemed just as motley. 'Did you find him?' Helena pressed.

'Who?'

'The dog, Marcus.'

'Oh! Yes.'

'I bet your lady client was really grateful!' Helena understood more about my business than I liked.

'Come off it. You know I never sleep with clients.' She gave me a look; Helena had been my client once herself. Telling her she was different from all the others somehow never carried weight.

The woman in search of the lost doggie had had more money than sense and astounding looks. My professional ethics were of course unimpeachable-but I had certainly considered making a play for her. At the time big brother Festus had convinced me that tangling with the moneyed classes was a bad idea. Now Marina's words cast a subtle doubt. I gazed at her. She giggled. She obviously assumed I had known what was going on; now I finally saw the reason Festus had advised me to steer clear of the pretty dog owner: he had been bedding her himself.

'Actually,' I told Helena gloomily, 'it was Festus who found the bloody dog.'

'Of course it was,' Marina piped in. 'He had it tied up at my house all along. I was livid. Festus pinched it from the baths so he could get to know the fancy skirt.' My brother, the hero! 'Didn't you twig?'

'Ah Marcus!' Helena soothed me, at her kindest (not so kind as all that). 'I bet you never got your bill paid either?'

True.

I was feeling abused.

'Look, when you two have finished mocking, I have things to do today-'

'Of course you have,' smiled Helena, as if she was suggesting I should hide in a barrel for a few hours until my blushes cooled.

'That's right. Repolishing my grimy reputation won't be a quick job.' It was best to be straight with her, especially when she was sounding facetious but looking as if she was trying to remember where she last put the vial of rat poison.

I kissed Marcia resoundingly and gave the child back to her mother. 'Thanks for the hospitality. If you remember anything helpful, let me know at once. I'm due for the public strangler otherwise.' Helena stood up. I put my arm round her shoulders and said to Marina, 'As you see, my time should really be being taken up by this lovely girl.'

Helena permitted herself a complacent sniff.

'Are you two getting married?' Marina asked sympathetically.

'Of course!' we both chimed. As a couple we lied well.

'Oh that's nice! I wish you both every happiness.'

One thing must always be said for Marina: she had a good heart.

I informed Helena I had had enough supervision for one day and was going to my next appointment alone. Helena knew when to let me make a stand. I felt she acquiesced too graciously, but that was better than a fight in the open street.

We were virtually at her parents' house, so I took her for a daughterly visit. I made sure I escorted her to within sight of the door. Stopping for goodbyes gave me a chance to hold her hand. She could manage without consolation, but I needed it.

'Don't hate me, sweetheart.'

'No, Marcus.' She would be a fool not to view me with caution, however. Her face looked guarded. 'I always knew you had a colourful life behind you.'

'Don't judge me too harshly.'

'I think you're doing that yourself.' Maybe somebody had to. 'Marina seems a nice girl,' Helena said. I knew what that meant.

'You're hoping someone some day will snap her up.'

'I don't see why not.'

'I do. The men she hangs around with know she's not looking for a husband. It makes it easier for them-not having to worry about the fact they all have wives!'

Helena sighed.

We were standing on a corner of the great Appian Way. It was about as public as the Forum of the Romans on a quiet day. Brown-clad slaves with baskets and amphorae on their bent shoulders butted up the street in both directions trying to get in the way of five or six litters carrying ladies from refined homes. Workmen were chiselling unconvincingly at the dark bulk of the old aqueduct, the Aqua Marcia. A cart laden with marble slabs came by, struggling to mount the raised pavement as it lurched out of control. Three donkey-drovers waiting to overtake it, two old women with a goose, and the queue on a bench outside a barber's had tired of watching the cart and started to notice us.

To make the day memorable for everyone, I slid my arms around Helena Justina and kissed her. Rome is a city of sexual frankness, but even in Rome senators' daughters are rarely grappled on street corners by creatures who are obviously only one rank up from woodlice. I had caught her off guard. There was nothing she could do to stop me, and no reason for me to stop of my own accord. A small crowd collected.
