the shoreline of the house – sea bass, with their woolly-white flesh; grey mullet, that required high walls around their pond to prevent them leaping to freedom; flatfish and parrot fish and giltheads; lampreys and congers and hake.
But by far the most expensive of Ampliatus's aquatic treasures – he trembled to think how much he had paid for them, and he did not even much like fish – were the red mullet, the delicate and whiskered goatfish, notoriously difficult to keep, whose colours ran from pale pink to orange. And it was these that the slave had killed. Whether by malice or incompetence, Ampliatus did not know, nor care, but there they were: clustered together in death as they had been in life, a multi-hued carpet floating on the surface of their pond, discovered earlier that afternoon. A few had still been alive when Ampliatus was shown the scene, but they had died even as he watched, turning like leaves in the depths of the pool and rising to join the others. Poisoned, every one. They would have fetched six thousand apiece at current market prices – one mullet being worth five times as much as the miserable slave who was supposed to look after them – and now they were fit only for the fire. Ampliatus had pronounced sentence immediately: 'Throw him to the eels!'
The slave was screaming as they dragged and prodded him towards the edge of the pool. It was not his fault, he was shouting. It was not the food. It was the water. They should fetch the aquarius.
The aquarius!
Ampliatus screwed up his eyes against the glare of the sea. It was hard to make out the shapes of the writhing slave and of the two others holding him, or of the fourth, who held a boat-hook like a lance and was jabbing it into the doomed man's back – mere stick-figures, all of them, in the haze of the heat and the sparkling waves. He raised his arm in the manner of an emperor, his fist clenched, his thumb parallel with the ground. He felt godlike in his power, yet full of simple human curiosity. For a moment he waited, tasting the sensation, then abruptly he twisted his wrist and jammed his thumb upward. Let him have it!
The piercing cries of the slave teetering on the edge of the eel-pond carried up from the seafront, across the terraces, over the swimming pool and into the silent house where the women were hiding.
Corelia Ampliata had run to her bedroom, thrown herself down on the mattress, and pulled her pillow over her head, but there was no escaping the sound. Unlike her father, she knew the slave's name – Hipponax, a Greek – and also the name of his mother, Atia, who worked in the kitchens, and whose lamentations, once they started, were even more terrible than his. Unable to bear the screams for more than a few moments, she sprang up again and ran through the deserted villa to find the wailing woman, who had sunk against a column in the cloistered garden.
Seeing Corelia, Atia clutched at her young mistress's hem and began weeping at her slippered feet, repeating over and over that her son was innocent, that he had shouted to her as he was being carried away – it was the water, the water, there was something wrong with the water. Why would nobody listen to him?
Corelia stroked Atia's grey hair and tried to make such soothing noises as she could. There was little else that she could do. Useless to appeal to her father for clemency – she knew that. He listened to nobody, least of all to a woman, and least of all women to his daughter, from whom he expected an unquestioning obedience – an intervention from her would only make the death of the slave doubly certain. To Atia's pleas she could only reply that there was nothing she could do.
At this, the old woman – in truth she was in her forties, but Corelia thought of slave years as being like dog years, and she appeared at least sixty – suddenly broke away and roughly dried her eyes on her arm.
'I must find help.'
'Atia, Atia,' said Corelia gently, 'who will give
