The actual performance bore out my disquiet. My laborious redraft had been tossed aside. All the actors ignored it. As the action evolved they repeatedly referred to the missing moneylender, even though he would never appear, then in the last act they improvised a few haphazard speeches to get around the problem. The plot, which I had so wittily resurrected, dwindled into ludicrous tosh. For me, the most bitter insult was that the audience swallowed the gibberish. The sombre Nabataeans actually applauded. They stood up politely, clapping their hands above their heads. Somebody even threw what looked like a flower, though it may have been an unpaid laundry bill.

'You're upset!' Helena observed, as we fought our way to the exit. We barged past Philocrates, who was hanging around the gateway, showing off his profile to admiring women. I steered Helena through a smaller group of men with entranced expressions who were waiting for the beauteous Byrria; she had taken herself off promptly, however, so they were looking over anything else in a long skirt. Having my nobly reared girlfriend mistaken for a flute girl was now my worst nightmare. 'Oh, don't let it worry you, Marcus my love:" She was still talking about the play.

I explained to Helena succinctly that I didn't give a damn what a group of illogical, illiterate, impossible thespians did on stage or off it, and that I would see her in a while. Then I strode off to find somewhere I could kick rocks in decent solitude.

It came on to rain more heavily. When you're down, Fortune loves stamping on your head.

Tearing off ahead of everyone else, I reached the centre of our encampment. That was where the heavier waggons were drawn up in the hope that our encircling tents would deter sneak-thieves. Hopping over the nearest tailboard I took shelter under the ragged leather roof that protected our stage properties from the weather. It was my first chance to inspect this battered treasure trove. After I had finished swearing about the performance, I devised a ferocious speech of resignation that ought to leave Chremes whimpering. Then I fetched out my tinderbox, wasted half an hour with it, but eventually lit the large lantern that was carried on stage in scenes of night-time conspiracy.

As the pale flame wandered around dangerously in its ironwork container, I found myself crouching up against a small shrine (large enough to hide behind for overhearing secrets). Stacked opposite were several painted doorways, meant to distinguish the neighbouring houses that featured in so much of the New Comedy. These had not been used in tonight's Pirate Brothers in order to save them from the wet. Instead the scene, which was originally 'A Street in Samothrace', had been redesignated 'A Rocky Coast' and 'The Road to Miletus'; Chremes had simply played Chorus and announced these arbitrary locations to his hapless audience.

I struggled to settle more comfortably. Under my elbow was an old wooden log with a greying shawl nailed to it (the 'baby'). Sticking out above my head was a gigantic sword of curved design. I assumed it was blunt – then cut my finger on the edge while testing out my assumption. So much for scientific experiment. Wicker baskets mostly overflowed with costumes, shoes and masks. One basket had toppled over, showing itself nearly empty apart from a long set of rattly chains, a large ring with a big red glass stone (for recognition of long-lost offspring), some parcels of shopping, and a brown jar containing a few pistachio shells (the ever-present Pot of Gold). Behind it were a stuffed sheep (for sacrifice) and a wooden pig on wheels that could be towed across the stage by Tranio in his role as a merrily wittering Clever Cook who cracked thousand-year-old jokes about preparations for the Wedding Feast.

Once I had finished gloomily surveying the torn and faded panoply with which I was sharing this waggon, my thoughts naturally turned again to issues like Life, Fate, and however did I come to end up in this tip being paid zero for an unappealing job? Like most philosophy it was a waste of time. I noticed a woodlouse and began timing his progress, taking bets with myself about which direction he would wander in. I had grown cold enough to think I would now return to my own bivouac and allow Helena Justina to bolster my esteem, when I heard footsteps outside. Somebody stamped up to the waggon, the end flap was beaten aside, there came a flurry of irritated movement, and then Phrygia hauled herself inside. Presumably she too was seeking privacy, though she did not appear bothered by finding me.

Phrygia was as long as a leek; she could overtop most men. She increased her advantage of height by wearing her hair in a coronet of frizzled curls, and by teetering about on frightful platformed shoes. Like a statue that had been purposely designed to stand in a niche, her front view was perfectly finished, but her back had been left in the rough. She was a model of immaculate face paint, with a whole breastplate of gilt jewellery that crackled in layers upon the meticulous pleats of the stole across her bosom. Seen from behind, however, every bone pin pegging down her hairstyle was visible, the frontispiece jewellery all hung from a single tarnished chain that had worn a red furrow in her scrawny neck, the stole was rumpled, the shoes were backless, and her gown was hoicked together and pinned in clumps in order to provide the more elegant drape on her frontal plane. I had seen her walk down a street with a sideways glide that preserved her public image almost intact. Since her stage presence was strong enough to entrance an audience, she did not care if the louts behind the back wall sneered.

'I thought it might be you skulking here.' She threw herself against one of the costume baskets, flapping her sleeves to shake off drops of rain. Some fell on me. It was like being joined on a small couch by a thin but energetic dog.

'I'd better be off,' I muttered. 'I was just sheltering – '

'I see! Don't want that girl of yours to hear you've been closeted in a waggon with the manager's wife?' I settled back weakly. I like to be polite. She looked fifteen years older than me, and might be more. Phrygia favoured me with her bitter laugh. 'Consoling the ranks is my privilege, Falco. I'm the Mother of the Company!'

I joined in the laughter, as one does. I felt threatened, wondering briefly if accepting consolation from Phrygia was an obligation for men in the troupe. 'Don't worry about me. I'm a big boy – '

'Really?' At her tone, I shrank mentally. 'So how was your first night?' she challenged.

'Let's say I can now see how Heliodorus might have turned his back on society!'

'You'll learn,' she consoled me. 'Don't make it so literary. And don't waste time sticking in political allusions. You're not bloody Aristophanes, and the people who are paying for tickets are not educated Athenians. We're acting for turnips who only come to talk to their cousins and fart. We have to give them a lot of action and low-level jokes, but you can leave all that to us on stage. We know what's required. Your job is to hone the basic framework and remember the simple motto: short speeches, short lines, short words.'

'Oh, and I foolishly thought I would be handling major themes of social disillusionment, humanity and justice!'

'Skip the themes. You're handling old envy and young love.' Like most of my career as an informer, in fact.

'Silly me!'

'As for Heliodorus,' Phrygia went on, with a change of tone, 'he was just nasty to begin with.'

'So what was his problem?'

'Juno only knows.'

'Did he make enemies with anyone in particular?'

'No. He was fair; he hated everyone.'

'And everyone was even-handed with their loathing in return? What about you, Phrygia? How did you get on with him? Surely an actress of your status was beyond reach of his spite?'
