The porter at the Camillus house refused to recognize me; I nearly had to thump him, ruining my good mood and neat attire. The senator and Julia Justa had already left. Fortunately Helena was waiting for me quietly in the hall, so she came out in response to the kerfuffle, already aboard her chair. She ran an eye over me through the window, but it was not until we reached the Palatine that I had a proper chance to inspect her in return.

She gave me quite a shock.

I suppose money makes its point. As soon as I handed her out, wreathed in her ladylike mantle with a half-veil demurely tucked from ear to ear, I started to get that sense of unease when someone you know is so dressed up they seem to be a stranger. Unwrapped, I found her mother’s miserable maids had really done their duty by the daughter of the house. Once they worked her over with the manicure prodders and eyebrow tweezers, curling tongs and earwax scoops, left her fermenting all afternoon in a mealy flour face mask, then finished her off with a delicate sponging of red ochre across the cheekbones and a fine gleam of antimony above the eyes, Helena Justina was bound to be presentable enough, even to me. In fact she looked burnished from the glint of the filigree tiara clipped around her elaborate hair to the beaded slippers sparkling through the flounce at the hem of her gown. She was bare-armed in sea-green silk. The effect was of a cool, tall, distinctly superior naiad.

I looked away. I looked back, clearing my throat.

I confessed somewhat hoarsely that I had never been out on the town with a naiad before. “If you were on the beach at Baiae, there would be a strong danger some salty old sea god would throw you on your back to ravish you on a mattress of bladderwrack!”

She said she would punch him in the fins with his trident; I told her the attempt would still be worth his while.

We joined the slow throng that was wending its way to the dining room. This procession passed through Nero’s grotesque corridors where gold fretted the pilasters, arches and ceilings in such quantity that it merged into one glaring wash of paint. Meticulous fauns and cherubs pirouetted under pergolas where roses ran riot without season, in detail so delicate that once the artists’ scaffolding came down from the high walls the frescos could only be appreciated by wandering flies and moths. I felt glassy-eyed with luxury, like a man who had lost his vision staring at the sun.

“You’ve had your hair cut!” Helena Justina accused, muttering at me sideways as we went.

“Like it?”

“No,” she reported frankly. “I liked you with your curls.”

Praise be to Jupiter, the girl was still herself. I glared in return at her modishly frazzled topknot.
