I stepped inside and closed the door behind me. Eco was peacefully snoring. I reached down and touched the soft shock of hair across his forehead, feeling a sudden welling of tenderness for him and a longing to protect him – but from whom, and what? Most of all I felt cold and wet, and so weary I could hardly take another step or think another thought. I stripped off my sodden tunic and dried myself as best I could with a blanket, then pulled back the coverlet on my bed and fell onto my back, desperate for sleep.

Something hard and sharp stabbed my back. I jumped to my feet. The night's surprises were not over.

I stared down and could only see a dark shape on the cushion. I bolted naked from the room to fetch a lamp from the hall. By its lurid glow I studied the thing that someone had left in my bed. It was a figurine the size of my hand carved in porous black stone, a grotesque creature with a hideous face. Its eyes were set with tiny shards of red glass that glinted in the light. It was the sharp, beaked nose that had stabbed me.

'Have you ever seen anything uglier?' I muttered. Eco made a noise in his throat and rolled towards the wall, sound asleep. Like Gelina, he would have slept through a train of dancing girls with cymbals. I set the little monster on the windowsill, not knowing what else to do with it and too weary to think about it..

I set the lamp on a table and left it burning, not because I trusted the light's protection but because I was too tired to put it out. I fell into my bed and was almost instantly asleep. Just before Morpheus claimed me, I realized with a shiver why the thing in my bed had been put there. Friendly or not – gift, warning, or curse – it was an act of sorcery. We had come to the region of the Cup, where the earth breathes sulphur and steam, where the ancient inhabitants practised earth magic and the colonizing Greeks brought new gods and oracles. That knowledge unsettled my dreams and clouded my sleep, but nothing, not even dancing girls in the hallway, could have kept me awake an instant longer.

I winced at a sharp pain in my head, as if someone were poking me with a nettle, and opened my eyes to see Eco peering down at me, pursing his Lips thoughtfully. He was reaching out to tap at a spot on my forehead just below the scalp. I grunted and pushed his hand away. He winced sympathetically and drew back, shaking his head.

'Is it that bad?' I said, swinging my feet onto the floor and leaning forward to look into the mirror. Even by the grey light of dawn the bump was quite evident, a raised red knob that looked more painful than it felt. Eco held up my still-damp tunic with one hand and the oar with the other. He looked at me disapprovingly, demanding an explanation.

I began with my interview with Crassus – the bloodstains on the statue of Hercules, the evidence that Lucius Licinius was killed in his library, our employer's determined disinterest. I told him about the moving lamp at the boat-house, the periodic splashing as of something being dropped into the water, the steep descent, the deserted pier and boathouse, the oar swung against my head, the struggle in the water.

Eco shook his head at me angrily and stamped his foot.

'Yes, Eco, I was a fool, and a lucky one at that. I should have fetched you out of bed to come with me instead of rushing down to investigate. Or better yet, I should have brought Belbo along to play bodyguard and left you in Rome to look after Bethesda.' That suggestion riled him even more.

'I have no idea who struck me. As for the boathouse and the pier, there was nothing to be seen, at least not by night. How I hate the water!' I remembered the burning draught of saltwater in my throat, the struggling and thrashing; my hands were suddenly shaky and I had to struggle for breath. Eco's anger vanished and his arm was around me, holding me right. I caught my breath and patted his hand.

'And if my adventure at the boathouse was not enough, I came back to find this in my bed.' I stepped to the window and picked up the figurine. The black, porous stone seemed clammy to the touch. I had kept waking up during the night to see it staring down at me from the windowsill, its ugly face weirdly illuminated by the lamplight, its red eyes shining. At one point I actually thought I saw it moving, undulating in a kind of dance – but that was only a dream, of course.

'What does it remind you of?'

Eco shrugged.

'I've seen something like it before; it reminds me of an Egyptian household god of pleasure, Bes they call him, an ugly little fellow who brings bliss and frivolity into the house. So hideous, if you didn't know he was friendly you might be frightened of him – a huge, gaping mouth, staring eyes, a pointed nose. But this isn't Bes; it's an hermaphrodite, for one thing – see the tiny round breasts, and the little penis? Moreover, the workmanship is not Egyptian. It seems to have been made from local stone, that soft, porous black stuff one finds on the slopes of Vesuvius. Not an easy medium to work in, I imagine, too crumbly, so it's hard to say whether the workmanship is crude or simply rushed. Who could have fashioned such a thing, and why was it put in my bed?

'The practice of sorcery is very popular here on the Cup, much more so than in Rome. There's a great deal of indigenous magic among those whose families have always lived here, whose race predates the Romans in these parts. Then the Greeks settled here, bringing their oracles with them. Even so, this strikes me as a thing someone from the East might carve, and more likely a woman than a man. What do you think, Eco – is one of the household slaves trying to cast a spell on me? Or could it be-'

Eco clapped and gestured toward the door behind me, where the little slave boy Meto stood waiting expectantly, bearing a tray of bread and fruit. I saw his eyes dart nervously about the room. I hid the figurine from sight while I turned, so that when I faced him I held it behind my back. I smiled at him. He smiled back. Then I produced the figurine and thrust it onto the tray.

He let out a little gasp.

'You've seen this thing before?' I said accusingly.

'No!' he whispered. That might be literally true, given the frantic way he averted his eyes.

'But you know what it is, and where it comes from?'

He was silent, biting his hp. The tray trembled. An apple pitched onto its side and rolled into a bunch of figs. I took the tray from him and set it on the bed, picked up the statuette and thrust it against his nose. He peered at it, cross-eyed, and then shut his eyes tightly. 'Well?' I pressed.

'Please, if I tell you, it may not work…'

'What? Speak clearly.'

'If I explain it to you, the test may come to nothing.' 'Do you hear that, Eco? Someone is testing me. I wonder who, and why.' Meto quailed under my glare. 'Please, I don't really understand it all myself, it's just something I happened to overhear.' 'Overhear? When?' 'Last night.' 'Here in the house?' 'Yes.'

'I suppose you must overhear many things, coming and going as you do.'

'Sometimes, but never on purpose.' 'And whom did you overhear last night?' 'Please!'

I looked at him for a long moment, then stepped back and let the sternness fall from my face. 'You understand why I'm here, don't you, Meto?'

He nodded. 'I think so.'

'I'm here because you and many others are in very grave danger. I want to help you if I can.'

He looked at me sceptically. 'If I could be sure of that…' he whispered in a very small voice.

'Be sure of it, Meto. I think you know how great the danger is.' He was only a little boy, far too young to be facing the prospect Crassus had planned for him. Had he ever seen a man put to death? Was he old enough to really understand? 'Trust me, Meto. Tell me where this statue came from.'
