Lindsey Davis - The Silver Pigs

Slowly the gilded triumphal chariot thundered by. Vespasian looked, as he himself said afterwards, as though he was calling himself a fool to have wasted a day on this endlessly crawling parade. I did not cheer, but despite myself I laughed.

After him, Titus. Titus in a second great chariot, looking as if his heart was going to burst. Finally Domitian, the junior prince, handsome as mustard on a prancing white horse.

They had done it. They were here. Three Sabine provincials no one had ever heard of until last year had, with good luck and some merit, made themselves dynastic princes in Rome.

I turned away. Behind the three Flavians, the full mass of the army now came marching in: line after line of standard-bearers, trumpeters, baton-wielding officers in tall crimson crests, augurs, engineers, then the endless ranks of foot sloggers six deep, swinging along in the easy tramp that had taken the legions effortlessly throughout the world. Regulars piled through the streets in cohort after glittering cohort, followed by their exotic auxiliaries swarthy-faced archers in shimmering scale armour mounted on swift ponies, then heavier cavalry, ominous today in chased golden face masks that made them quite expressionless as they shook their feathered spears in unison.

There was going to be a long wait while the Emperor climbed the Gemonian steps on his knees, then more delay while he made formal sacrifice at the Temple of Jupiter on Capitol Hill. Turning back the way I had come would be impossible for another hour. I decided to circle right round the Palatine and weave back to the others along the Caelian side. This would enable a discreet check of certain premises on the way.

I followed the line of the Cloaca Maxima, the Great Sewer, built five hundred years ago to drain the marshes round the Forum and the river side of the Aventine. My road soon brought me among the spice markets, where I came upon a watchman guarding the manhole where sewer men still plugged away daily under Nap Lane. They were not here today. On a public holiday no one works; only watchmen sometimes watch, if they want somewhere quiet to get drunk. This watchman had guzzled his way through one raw skinful and was taking a nap to encourage him for more.

So far nothing unexpected. Yet at the head of the alley I spotted a girl I vaguely thought I knew.

"Naissa?" It was Helena Justina's constantly abandoned maid.

She had made up her face with borrowed paint in honour of the day. She had done it in poor light so in broad sunshine the final effect passed beyond enhancing her features to a vivid glaze of colour; it gave her an unnatural, astonished stare.

"Where is your lady, girl?" I demanded anxiously.

Tn her father-in-law's warehouse. I was frightened to go any further; she told me to wait here."

"It's just a warehouse, nothing sinister; you ought to have gone in with her!"

"What shall I do now?" Naissa queried nervously, widening her fantastically painted eyes.

"Whatever she told you, Nai'ssa!" I instructed unsympathetically, while my mind raced.

Having informed Helena Justina yesterday that I was not free to go to the warehouse, I knew I ought to abandon my present plan. I wanted very badly to see her, but turned away. Now I had accepted that at least one of her close relations was involved in the conspiracy, facing her was hard to contemplate. Yet all the time I kept remembering that the warehouse was where Sosia had been murdered. To leave Helena alone there would have been even more difficult.

"Are you Didius Falco?" Naissa asked, with a glimmer of recognition in her eyes. I stopped. "She told me to go to your house with this"

She was holding something out. It was wrapped in a scarf, but the weight felt familiar as soon as it dropped into my hand.

"Was there a message?"

"No, sir."

Already I realized something serious was happening. I said urgently to the maid: "Go back and watch the Triumph with the family again. Tell Helena Justina's mother, as discreetly as you can, that your lady is under my escort now. Her father should be attending the sacrifice, no need to bother him yet. But if Helena does not reappear by the time of the celebration dinner, go immediately to the senator and tell him where we are."

The next time I began to walk it was rapidly down Nap Lane. As I went, I unfolded Helena's scarf.

What I held in my hand then was a bracelet of British jet, fashioned in interlocking pieces like whale's teeth. It was the bracelet that Sosia Camillina once gave to me, which had been stolen from me on the doorstep of the senator's house.

Sometimes a case consists of a progression of facts that lead you from one to another in a logical sequence; with these an informer who has any sort of brain can do all the work himself, at his own pace. Sometimes it is different. All you can do is stir the mire, then keep prodding so pieces of flotsam float to the top, while you stand there and watch for some putrid relic to emerge and at last make sense. Something had swirled into view now; the only problem was, it must be Helena who had stirred the mire. But if Helena had found this bracelet where Sosia found her list of names, it made sense. And it meant Helena Justina now knew who the last conspirator was. To keep it safe, I buckled the bracelet onto my belt.

When I walked into the alley some things had changed, some were exactly the same. Rank weeds lolled against decaying doorposts where fungus gleamed like shrimp roe; further on, new chains flaunted bright padlocks on businesslike new doors. It must be a place where property ownership constantly changed, shifting with the storms of commerce, be they blown up on the ocean by the gods in their wicked mood, or manufactured in the Emporium by speculating men.

At the Marcellus warehouse there seemed little alteration on the outside. In the lane a broken down waggon which I remembered had been shunted along a couple of yards; I was surprised it could be moved. I noticed the difference because there was a manhole with its cover off where the clapped-out vehicle had stood before in apparently permanent decay. The yard gates were closed, but unlocked. I walked in on hurried feet.

When I came here looking for Sosia, the Marcellus warehouse had appeared almost abandoned. Since then, the sea routes to Alexandria had reopened, and evidently several triremes laden to swamping-point had made the trip for Pertinax while he was still alive and operating in trade. This was obviously a working unit now. A line of carts stood against the yard wall, and when I approached the warehouse door I could smell the difference from five paces away. Someone had left a great key in the outside lock. The twelve-foot door gave with a creak, though I had to lean against it with my whole body weight to heave the monster ajar.

What a place! Now that Pertinax and his partner Camillus Meto had been using it again, the atmosphere was magical. But the dead silence told me nobody was here.

The pepper warehouse was a square, high, cluttered space, dimly lit from far above. Even now it was still less than half full, but on that warm afternoon the varied aromas of the rich goods inside hit me at the entrance like the whoomph of a well-sealed steam-room at the baths. Once my eyes focussed in the weird light I could see bell jars of root ginger standing in shadowy rows like pharaohs' statues lining the route to the tombs in some silent city of the dead. Sacks were piled in the centre of the floor stuffed with cloves, coriander, cardamoms and cinnamon bark. One entire wall wds lined with wooden stalls where I plunged to the elbow in peppercorns, black, white and green. I stuffed half a handful worth a year's salary into my pocket absentmindedly.

She was nowhere to be seen. I walked steadily up a long aisle of baskets and kegs to the back of the building, then returned. My eyes watered slightly. I stood in that dizzy fug of aromatic scents, like a man drowning in medicinal balsam.
