I took my time, moving surreptitiously. I glanced over to our table, meaning to signal to Helena, who had just been served by Polystratus. After several bad bouts of stomach upset, she avoided hotpots nowadays. I noticed that she quietly bent down and placed the bowl on the floor for Nux.

Minas had seen me coming, and had read my expression. I turned my back to the crowd and unfolded the napkin, showing Volcasius the jump weight. He gave an exaggerated start."How did you get that, Falco?'

"No – how did you get it, Volcasius?'

"It's the weapon that was used to kill Valeria.'

"I know.'

"I didn't kill her.' I knew that too."I was just doing your job for you,' Volcasius sneered.

He still believed he was better at my job than me. I remained calm. He was a witness. Minas needed him. Besides, although I would have got around to it, eventually, Volcasius had carried out the necessary search and I gave him credit."Where was this, Volcasius?'

"In his luggage pack.'

"Whose luggage pack?' Minas asked magisterially."Name him!'

"Polystratus.'

I turned back to the crowd. I thought Helena might be watching me, aware from the boys that I was on to something. Her attention was on something else. I saw a horrified expression seize her. Her stole

slipped off, as she raised her arm and pointed, looking alarmed. She •was calling to Nux.

I was too far away but I started to run. I was shouting in panic for Aulus and Glaucus. Then I was yelling at the dog.

Nux had her nose down in Helena's foodbowl. The dog was carefully cleaning up a piece of bone against the side of the bowl. The bone was of crunchable size, but she lifted it out delicately and placed it on the ground for special treatment. As I reached her, a final fast lick revealed a gleam of metal. It was a man's ring. I had seen a smaller one just like it. a decent piece, gold, probably bought in Greece, since it had a squared-off Greek meander pattern… We had found Statianus.

I had a momentary flashback to the globular amphorae Polystratus unloaded at Corinth. My gorge rose as I remembered tasting tuna. I could hardly bear to think about what must have been hidden in the other containers. I dared not imagine the butchery involved in filling them.

I bent to retrieve the finger-bone and the ring. Nux straightened her short legs in guard mode. A low grumble emerged from the back of her throat in defence of her bone. At the same time, because I was her master, her short tail wagged madly.

Aghast, Helena slid from her dining couch. She banged a goblet hard on the table. Those closest had noticed; they stopped talking.

"Everyone!' Helena called out."Please stop eating.' The party noise subsided. People were already raising goblets. They thought it was a toast.

Polystratus abandoned his cauldron and moved towards Helena. Glaucus and Aulus went for him. Glaucus kicked out. I saw a couple of jabs and a lightning move, then Polystratus was lying on the ground, with Young Glaucus astride him, one arm pressed to his throat. His father must have taught him that; I must ask him to show me.

Nux noticed Polystratus too. The growl changed from mere warning to frantic barks. Gaius rushed to restrain her before she attacked.

Helena spoke again. For the rest of my life I would remember her there, standing tall and erect in her silvery blue gown, clear-voiced and desperate. Nobody who heard her would forget it lightly.

"Please, everybody, place your foodbowls back on the serving tables. We will collect them up. If you want to avoid nightmares, I beg of you all – Do not eat the stew!'
