Lindsey Davis - A dying light in Corduba

We stood respectfully in the colonnade while the troop of civic dignitaries squashed by, on their way to the theatre where a day of fun would take place. The procession was accompanied by some worried sheep and a skipping calf who clearly had not been told he was to form the next sacrifice. Persons who were pretending to be shepherds came past with brooms, supposedly for sweeping out stables; they also carried implements to light fumigatory fires. A couple of public slaves, clearly fire watchers, followed them with a water bucket, looking hopeful. Since the Parilia is not just any old rustic festival but the birthday of Rome, I bit back a surge of patriotic emotion (that's my story). A personification of Roma armed with shield and spear and a crescent moon on her helmet, swayed dangerously on a litter midway down the line. Helena half turned and muttered sarcastically, 'Roma Resurgans is rather perilous on her palanquin!'

'Show some respect, bright eyes.'

An offrcial statue of the Emperor teetered before us and nearly toppled over. This time Helena obediently said nothing, though she glanced at me with such a riotous expression that while the wobbly image of Vespasian was being steadied by its bearers I had to pretend a coughing fit. Helena Justina had never been a model for perfect sculptural beauty; but in a happy mood she had life in every flicker of her eyelashes (which were in my opinion as fine as any in the Empire). Her sense of humour was wicked. Seeing a noble matron mock the Establishment always had a bad effect on me. I mouthed a kiss, looking moody. Helena ignored me and found another tableau to giggle at.

Then, following her line of sight, I spotted a familiar face. One of the broad burghers of Corduba was sidestepping the shepherds as they wrestled with a wilful sheep. I recognised him at once, but a quick check with someone in the crowd confirmed his name: Annaeus Maximus. One of the two major oil producers at the dinner on the Palatine.

'One of those puffed-up dignitaries is on my list. This seems a good opportunity to talk to a suspect…'

I tried to persuade Helena to wait for me at a streetside foodshop. She fell silent in a way that told' me I had two choices: either to abandon her, and see her walk away from me for ever (except perhaps for a brief return visit to dump the baby on me) – or else I had to take her along.

I attempted the old trick of holding her face between my hands, and gazing into her eyes with an adoring expression.

'You're wasting time,' Helena told me quietly. The bluff had failed. I made one more attempt, squashing the tip of her nose with the end of my finger while smiling at her beseechingly. Helena bit my playful digit.

'Ow!' I sighed. 'What's wrong, my love?'

'I'm starting to feel too much alone.' She knew this was not the moment for a domestic heart-to-heart. Still, it never is the right time. It was better for her to be abruptly honest, standing beside a flower stall in a narrow Corduban street, than to bottle up her feelings and end up badly quarrelling later. Better – but extremely inconvenient while a man I wanted to interview was scuttling away amongst the ceremonial throng.

'I do understand.' It sounded glib.

'Oh do you?' I noticed the same frowning and withdrawn expression Helena had been wearing when I found her outside the basilica.

'Why not? You're stuck with having the baby – and obviously I can never know what that's like. But maybe I have troubles too. Maybe I'm starting to feel overwhelmed by the responsibility of being the one who has to look after all of us -'

'Oh, I expect you'll cope!' she complained, almost to herself. 'And I'll be poked out of the way!' She was perfectly aware it was her own fault she was stuck on her feet in a hot noisy street in Baetica.

Later that day, after a few enquiries, I left by the northwestern gate. Annaeus Maximus owned a lovely home outside the town walls, where he could plot the next elections with his cronies and his wife could run her salon for other elegant socially prominent women, while their children all went to the bad. Beyond the cemetery lining the route out of town lay a small group of large houses. An enclave of peace for the rich – disturbed only by the yapping of their hunting dogs, the snorting of their horses, the rioting of their children, the quarrelling of their slaves and the carousing of their visitors. As town houses go, the Annaeus spread was more of a pavilion in a park. I found it easy to identify – lit throughout, including the long carriage drive and surrounding garden terraces. Fair enough. If a man happens to be an olive oil tycoon, he can afford a lot of lamps.

The clique we had seen at the theatre were now assembling for a dinner party at this well-lit house with garlanded porticos and smoking torches in every acanthus bed. Men on splendid horses were turning up every few minutes, alongside gilded carriages which contained their over-indulged wives. I recognised many of the faces from the front rows at the theatre. Amidst the coming and going I also met the shepherds from the parilia parade; they may indeed have been here for ritual purification rites in the stables, though I thought it more likely they were actors who had come to be paid for their day's work in town. There were a few shepherdesses among them, including one with hugely knowing dark brown eyes. Once I would have tried to put a light of my own into eyes like that. But I was a responsible father-to-be now. Besides, I could never take to women with straw in their hair.

I made myself known to an usher. Baetican hospitality is legendary. He asked me to wait while he informed his master I was here, and as the whole house was pervaded by delicious cooking smells I promised myself I might be offered a piquant dish or two. There was bound to be plenty. Excess breathed off the frescoed walls. However, I soon learned that the Cordubans were as sophisticated as Romans. They knew how to treat an informer – even when he described himself as a 'state official and associate of your neighbour Camillus'. 'Associates' received short commons in Corduba – not so much as a drink of water. What's more, I had to wait a damned long time before I got noticed at all.

It was evening. I had set out from town in the light, but the fitst stars were winking over the distant Mariana mountains when I was led outside to meet Annaeus Maximus. He had been mingling with his guests on one of the terraces, where they were soon to hold an outdoor feast, as is traditional at the Parilia. The supposed shepherds had really been setting fire to sulphur, rosemary, firwood and incense in at least one of the many stables so the smoke would purify the rafters. Now heaps of hay and straw were being burned on the well-scythed lawns, so that a few by now extremely tired sheep could be compelled to run through the fires. It's hard work being a ceremonial flock. The poor beasts had been on their trotters all day, and now they had to endure being ritually lustrated while humans stood around being sprinkled with scented water and sipping bowls of milk. Most of the men had one eye out for the wine amphorae, while the women kept flapping their hands about, in the vain hope of preventing their fabulous gowns being imbued with lustral smoke.

I was kept well back in a colonnade, and it wasn't to protect me from the sparks. The invited guests began to seat themselves for the feast out amongst the regimented topiary, then Annaeus stomped up to deal with me. He looked annoyed. Somehow I have that effect.

'What's this about?'

'My name is Didius Falco. I have been sent from Rome.'

'You say you're a relative of Camillus?'

'I have a connection -' Among snobs, and in a foreign country, I had no qualms about acquiring a respectable patina by shameless usage of my girlfriend's family. In Rome I would have been more circumspect.
