'This is cruelty!' murmured Phrygia.

'No,' said Thalia in a tone that meant to be heeded. 'You made your decision. If you've suddenly decided to change your mind after all these years, the other party deserves some warning. Don't push me! Maybe I'll introduce you after the play:'

Chremes had given up trying to interest me in his troubles. Looking frustrated, Phrygia felt silent and allowed her husband to lead her away.

I was not the only one who had overheard the intriguing snatch of conversation. Davos found some excuse to dally behind, and I heard him say to Thalia, 'I remember Tegea!' I felt Helena kick my ankle, and obediently joined her in pretending to be very busy laying out our meal. As usual Davos was being blunt. 'She wants to find the baby.'

'So I gathered,' Thalia returned rather drily, tipping her head back and giving him a challenging stare. 'A bit late! Actually, it's not a baby any more.'

'What happened?' Davos asked.

'When people give me unwanted creatures, I generally bring them up.'

'It lived then?'

'She was alive the last time I saw her.' As Thalia informed Davos, Helena glanced at me. So Phrygia's baby had been a girl. I suppose we had both already worked that out.

'So she's grown up now?'

'A promising little artiste,' Thalia said grittily. That too was no surprise to some of us.

Seeming satisfied, Davos grunted, then went on his way after Chremes and Phrygia.

'So! What happened at Tegea?' I tackled our companion innocently when the coast was clear. Thalia would probably have said that men are never innocent.

She shrugged, pretending indifference. 'Not a lot. It's a tiny Greek town, just a blot on the Peloponnese.'

'When were you there?'

'Oh: how about twenty years ago?'

'Really?' We both knew exactly where the conversation was leading. 'Would that have been about the time our stage manager's wife missed her famous chance to play Medea at Epidaurus?'

At this, Thalia stopped playing at being unconcerned and burst into guffaws. 'Get away! She told you that?'

'It's common currency.'

'Common codswallop! She's fooling, Falco.' Thalia's tone was not unpleasant. She knew most people spend their lives deluding themselves.

'So are you going to give us the real story, Thalia?'

'I was just starting out. Juggling – and the rest!' Her voice dropped, almost sadly. 'Phrygia play Medea? Don't make me laugh! Some slimy producer who wanted to get his hand up her skirt convinced her he could swing it, but it would never have happened. For one thing – you should know this, Falco -Greeks never allow women actresses.'

'True.' It was rare in Roman theatre too. But in Italy actresses had done mime plays for years, a vague cover for striptease acts. In groups like ours, with a manager like Chremes who was a pushover for anyone forceful, they could now earn a crust in speaking parts. But groups like ours never took part in the ancient Greek mainland festivals.

'So what happened, Thalia?'

'She was just a singer and dancer in the chorus. She was drifting about with grand ideas, just waiting for some bastard to con her into believing she would make the big time. In the end, becoming pregnant was a let-out.'

'So she had the baby – '

'That's what tends to happen.'

'And she gave it away at Tegea?'

By now this was fairly obvious. Only yesterday I had seen a tall, thin, slightly familiar twenty-year-old who I knew had spent her childhood fostered out. I remembered that Heliodorus was supposed to have told Phrygia that her daughter had been seen somewhere by someone he knew. That could be Tranio. Tranio had appeared at the Vatican Circus; Thalia had known him there, and he presumably knew her troupe, especially the girls if his current form was indicative. 'I suppose she gave it to you, Thalia? So where is the child now? Could Phrygia need to look in somewhere like Palmyra, I wonder:'

Thalia tried just smiling knowingly.

Helena joined in, saying quietly, 'I think we could tell Phrygia who her baby is now, Marcus.'

'Keep it to yourself!' commanded Thalia.

Helena grinned at her. 'Ooh Thalia! Don't tell me you're considering how you can cheat Phrygia.'

'Who, me?'

'Of course not,' I weighed in innocently. 'On the other hand, wouldn't it be a nuisance if just when you'd found your valuable water organist, some tiresome relation popped out of the rocky scenery, dying to tell the girl she had a family, and keen to whisk her off to join quite another company than yours?'

'You bet it would!' agreed Thalia, in a dangerous tone that said she was not intending to let Sophrona meet such a fate.

Musa turned up at that moment, allowing Thalia to shrug off the Phrygia incident. 'What kept you? I was starting to think Pharaoh must have got out!'

'I took Zeno for a swim at the springs; he didn't want to be brought back.'

My mind boggled at the thought of trying to persuade a giant python to behave himself. 'What happens when he gets his own ideas and starts playing up?'

'You grab his neck and blow in his face,' Musa told me calmly.

'I'll remember that!' giggled Helena, glancing teasingly at me.

Musa had brought with him a papyrus, closely written in the angular script I vaguely remembered seeing on inscriptions at Petra. As we sat down to eat he showed it to me, though I had to ask him to translate.

'This is the letter I mentioned, Falco, from Shullay, the old priest at my temple. I had sent to ask him if he could describe the man he saw coming down from the High Place just before we saw you.'

'Right. Anything useful?'

Musa ran his finger down the letter. 'He starts by remembering the day, the heat, the peacefulness of our garden at the temple:' Very romantic, but not what I call evidence. 'Ah. Now he says, " I was surprised to hear somebody descending from the High Place so rapidly. He was stumbling, and falling over his feet, though otherwise light of step. When he saw me, he slowed up and began whistling unconcernedly. He was a young man, about your age, Musa, and also your height. His body was slim. He wore no beard. He wore the hat…" Shullay found the hat later, cast aside behind rocks lower down the mountain. You and I must have missed it, Falco.'

I was thinking fast. 'It doesn't add much, but this is very useful! We have six possible male suspects. We can certainly now eliminate some of them on Shullay's evidence alone. Chremes, and also Davos, are both too old and too heavy to fit the description.'

'Philocrates is too small,' Musa added. He and I both grinned.

'Besides, Shullay would certainly have mentioned if the man was quite so handsome! Congrio may be too slight. He's so weedy I think if he had seen Congrio, Shullay would have made more of his poor stature. Besides, he can't whistle. That leaves us,' I concluded quietly, 'with only Grumio and Tranio.'

Musa leaned forwards, looking expectant. 'So what are we to do now?'

'Nothing yet. Now I'm certain it has to be one of those two, I'll have to identify which one we definitely want.'

'You cannot interrupt your play, Falco!' Thalia commented reprovingly.

'No, not with a rapacious garrison screaming for it.' I applied a competent expression that probably fooled no one. 'I'll have to do my play as well.'
