The slave who came to fetch me on that unseasonably warm spring morning was a young man, hardly more than twenty.

Usually, when a client sends for me, the messenger is a slave from the very lowest rung of the household — a grub, a cripple, a half-wit boy from the stables stinking of dung and sneezing from the bits of straw in his hair. It's a kind of formality; when one seeks out the services of Gordianus the Finder, one keeps a certain distance and restraint. It's as if I were a leper, or the priest of some unclean Oriental cult. I'm used to it. I take no offence — so long as my accounts are paid on time and in full.

The slave who stood at my door on this particular morning, however, was very clean and meticulously groomed. He had a quiet manner that was respectful but far from grovelling — the politeness one expects from any young man addressing another man ten years his elder. His Latin was impeccable (better than mine), and the voice that delivered it was as beautifully modulated as a flute. No grub from the stables, then, but clearly the educated and pampered servant of a fond master. The slave's name was Tiro.

'Ofthe household of the most esteemed Marcus Tullius Cicero,' he added, pausing with a slight inclination of his head to see if I recognized the name. I did not. 'Come to seek your services,' he added, 'on the recommendation of—'

I took his arm, placed my forefinger over his lips, and led him into the house. Brutal winter had been followed by sweltering spring; despite the early hour, it was already far too hot to be standing in an open doorway. It was also far too early to be listening to this young slave's chatter, no matter how melodious his voice.My temples rolled with thunder. Spidery traces oflightning flashed and vanished just beyond the corners of my eyes.

'Tell me,' I said, 'do you know the cure for a hangover?'

Young Tiro looked at me sidelong, puzzled by the change of subject, suspicious of my sudden familiarity. 'No, sir.'

I nodded. 'Perhaps you've never experienced a hangover?'

He blushed slightly. 'No, sir.'

'Your master allows you no wine?'

'Of course he does. But as my master says, moderation in all things—'

I nodded. I winced. The slightest movement set off an excruciating pain. 'Moderation in all things, I suppose, except the hour at which he sends a slave to call at my door.'

'Oh. Forgive me, sir. Perhaps I should return at a later hour?'

'That would be a waste of your time and mine. Not to mention your master's. No, you'll stay, but you'll speak no business until I tell you to, and you'll join me for breakfast in the garden, where the air is sweeter.'

Itookhis arm again,led him through the atrium, down a darkened hallway, and into the peristyle at the centre of the house. I watched his eyebrows rise in surprise, whether at the extent of the place or its condition I couldn't be sure. I was used to the garden, of course, but to a stranger it must have appeared quite a shambles — the willow trees madly overgrown, their hanging tendrils touching tall weeds that sprouted from dusty ground; the fountain at the centre long ago run dry, its little marble statue of Pan pocked with age; the narrow pond that meandered through the garden opaque and stagnant, clogged with Egyptian rushes growing out of control. The garden had gone wild long before I inherited the house from my father, and I had done nothing to repair it. I preferred it as it was — an uncontrolled place of wild greenness hidden away in the midst of orderly Rome, a silent vote for chaos against mortared bricks and obedient shrubbery. Besides, I could never have afforded the labour and materials to have the garden put back into formal condition.

'I suppose this must be rather different from your master's house.' I sat in one chair, gingerly so as not to disturb my head, and indicated that Tiro should take the other. I clapped my hands and instandy regretted the noise. I bit back the pain and shouted,

'Bethesda! Where is that girl? She'll bring us food in a moment. That's why I answered the door myself — she's busy in the pantry. Bethesda!'

Tiro cleared his throat. 'Actually, sir, it's rather larger than my master's.'

I looked at him blankly, my stomach rumbling now in competition with my temples. 'What's that?' 'The house, sir. Bigger than my master's.' 'That surprises you?'

He looked down, fearing he had offended me. 'Do you know what I do for a living, young man?' 'Not exactly, sir.'

'But you know it's something not quite respectable — at least insofar as anything is worthy of respect in Rome these days. But not illegal — at least insofar as legality has any meaning in a city ruled by a dictator. So you're surprised to find me living in such spacious quarters, as ramshackle as they maybe. That's perfectly all right. I'm sometimes surprised myself And there you are, Bethesda. Set the tray here, between me and my unexpected but perfectly welcome young guest.'

Bethesda obeyed, but not without a sidelong glance and a quiet snort of disdain. A slave herself Bethesda did not approve of my keeping informal company with slaves, much less feeding them from my own pantry. When she had finished unloading the tray, she stood before us as if awaiting further instructions. This was merely a pose. It was obvious to me, if not to Tiro, that what she chiefly wanted was a closer look at my guest.

Bethesda stared at Tiro, who seemed unable to meet her gaze. The corners of her mouth drew back. Her upper Hp compressed and curled itself into a subtle arc. She sneered.

On most women, a sneer implies an unattractive gesture of disgust. With Bethesda one can never be so certain. A sneer does nothing to spoil her dark and voluptuous allure. In fact, it may increase it. And in Bethesda's limited but imaginative physical vocabulary, a sneer may mean anything from a threat to a brazen invitation. In this case, I suspect it was a response to Tiro's genteel lowering of the eyes, a reaction to his shy modesty — the sneer of the wily fox for the comely rabbit. I would have thought that all her appetites had been quenched the night before. Certainly mine had been.

'Does my master require anything more?' She stood with her hands at her sides, her breasts upraised, shoulders back. Her eyelids drooped, still heavy with paint from the night before. Her voice carried the sultry, slightly lisping accent of the East. More posing. Bethesda had made up her mind. Young Tiro, slave or not, was worth impressing.

'Nothing more, Bethesda. Run along.'

She bowed her head, turned, and made her way out of the garden and into the house, weaving sinuously between the hanging branches of willow. Once her back was turned, Tiro's shyness receded. I followed his gaze, from its origin at his wide-open eyes to its focal point, somewhere just above Bethesda's gently swaying buttocks. I envied him his modesty and shyness, his hunger, his handsomeness, his youth.

'Your master won't allow you to drink, at least not to excess,' I said. 'Does he allow you to enjoy a woman now and again?'

I was unprepared for the full depth and ruddy richness of his blush, as blood-red as a sunset over the open sea. Only the young with their smooth, soft cheeks and foreheads can blush that way. Even Bethesda was too old ever to blush like that again, assuming she was still capable of blushing at all.

'Never mind,' I said. 'I have no right to ask you such a question. Here, have some bread. Bethesda makes it herself and it's better than you might expect. A recipe passed down from her mother in Alexandria. Or so she says -1 have my suspicions that Bethesda never had a mother. And though I bought her in Alexandria, her name is neither Greek nor Egyptian. The milk and the plums should be fresh, though I can't vouch for the cheese.'
