It took two hours of debate before the Emperor was satisfied. The problem if it existed – was to be tackled with energy (though no extra men would be drafted in). The Prefect of the Vigiles would co-ordinate a special investigation, reporting to the Urban Prefect, who would report to Titus Caesar. Petronius Longus, – reporting to Rubella, reporting to the Prefect of the Vigiles, would identify the Emporium thieves, then evaluate whether they were a one-time strike or a more widespread threat. He had the right to advise any cohort tribune of a perceived danger in a particular sector, and all had a duty to assist him if required.

Anacrites was allocated no activity, though as a courteous gesture Titus said it was assumed the intelligence network would `keep a watching brief. We all knew this traditional phrase. It meant they were to keep out of the way.

As an exceptional measure only (this was heavily stressed by Vespasian), compensation would be offered to those traders at the Emporium who had lost goods last night, so long as their names appeared on the official list. Martinus had brought this for Petronius, sent in via a flunkey. Vespasian, who knew how to dodge fiddles, told a copy clerk to duplicate the list for him immediately.

I found myself assigned as a supernumerary officer, to work alongside Petronius. As usual with meetings, I came away not entirely clear what I was supposed to do.

‘S0 MARCUS, You went out for a quiet stroll up and down the Forum,' mused Helena, passing a platter of cheese savouries to Silvia. `By the time you came home, there was a major epidemic of crime, an imperial commission, and both of you hearty fellows had become special-enquiry officers?'

`Beats shopping for radishes,' I commented, though since we had guests, I had done that too. A householder has to be versatile.

`Working together will be nice for them,' remarked Arria Silvia. Petro's wife was petite and pretty. A bright, dainty girl with ribbons binding her hair, she was the kind I had once thought I wanted – until Petro acquired Silvia. She had a habit of stating the obvious; I suppose he found it comforting. They had been married for about seven years, and with three children to secure them in affection (or whatever it was), the union looked likely to last. I had therefore decided to put aside my reaction to Silvia. Which was that she brought me out in a rash.

Helena seemed able to get along with her, though their friendship lacked the warmth that I had noticed flowering naturally between Helena and my sister Maia, for instance. `I hope you two won't quarrel,' Helena said to me, smiling quietly. The shrewd one, mine. Whether or not he recognised what she meant, Petronius did not respond but went out to the balcony, where he lifted up his eldest daughter so she could pee into one of my pots of bulbs. This would probably kill them but I said nothing. He was a competent, uncomplicated father. A lesson to all of us.

I had the other two girls on my lap, playing with toys we had brought them. We were a happy party, stuffed with food and still enjoying a fine wine Petronius had donated from his extensive collection. Petro and Silvia had spent the early evening with us, laughing over stories of our travels in Syria. Friends do so love to hear about you suffering from ghastly climates, crooked moneychangers, and intense pain from poisonous arachnids. Saves them going on holiday themselves.

There had been so much to say about the scorpion nipping Helena and other lively memories that she and I had managed to avoid mentioning the one item that Silvia would think important: that we too might become a family.

I won't say Helena and I were sneakily pleased to keep it a secret. It was too much of an issue; we were not ready to laugh about it. But we were close enough friends for Helena to let me see her wry expression as Silvia prattled cheerfully about her own little girls. Silvia was hinting that it was about time Helena started to feel jealous yearnings. Eventually I- caught Helena's eye privately and winked at her. Silvia saw me do it. She shot a mock-scandalised look at Petronius, thinking I was being amorous. Petro pretended, as usual, that he had no idea at all what was going on.

The wink remained as a moment of stillness between Helena and me.

The women were taking a greater interest in our new task than either Petro or I wanted. Silvia had realised that Helena Justina was used to more free consultation than Petronius allowed her. She plunged in, picking over issues as tenaciously as she had earlier torn apart her chicken wings in peppered wine sauce.

Petronius and I had been allies for a long time. While Silvia speculated, we just talked quietly among ourselves.

`I want you to come over the road later, Petro. There's a property Smaractus is offering on the market. It's a dump, but a better one than this if it was done up a bit.'

`Done up a bit?' Petro squinted at me as if he had just caught me stealing wine jars from caupona counters. `Will Smaractus invest in improvements?'

`No, but I'm determined to find another place for us, even if I have to renovate a wreck myself.'

`I've not heard about this!' said Helena, taking one of Petro's girls from me. The other scampered off to play on the balcony. `Shouldn't I be the one to inspect the real estate?'

`And why can't you find another landlord?' Silvia put in.

I grinned at Helena. `The person who needs to inspect it is the kind associate who will be helping me install the new windows and floorboards!'

`Forget it!' exclaimed Petro, looking appalled. `You're a good carpenter.'

Helena laughed. `And he was a good friend!'

`I'm going to have my hands full with this initiative against the Emporium thieves,' said Petronius firmly. Sometimes he would help out in my crazy schemes; sometimes he didn't want to know. I let it drop. He was too stubborn to change his mind.

`So why has our bijou niche here lost its charm after so long?' Helena asked with the air of a Fury lightly fingering her scourge.

`I'm getting old. My legs are hating the stairs.' My beloved gave me a very sweet smile that meant I was toying with serious trouble.

`You should try it with three children hanging round your neck!' Silvia's remark was too close for comfort; I was dreading it with just one, particularly on Helena's behalf in the long months before our shrimp was born. I could already hear helpful relatives suggesting she should live somewhere more accessible, hoping that would be the first step to her leaving me for good.

Presumably Helena realised why I wanted a better billet. She leant back on her stool, cradling Tadia, and gave me a long stare. It was a challenge to tell Petro and Silvia the situation we were in. I returned the stare but stayed silent.

`Now doesn't Helena look good holding a baby!' Silvia rebuked me, clearly not even suspecting the truth. I had denied it to Petro, and he must have passed this on. Feeling mild pangs of guilt on his behalf, I condescended to survey Helena. She was wearing blue, with a tasteful row of bracelets covering her scarred arm, and silver earrings on which I had squandered a week's earnings one day in Palmyra just because I knew she was enjoying herself travelling the world with me.

She did look good. She looked healthy, calm and sure of herself. As she gripped the child – who was trying to fling herself too the floor to see if landing hard on boards would hurt – Helena's big brown beautiful eyes sent me another dare.

I stayed calm. I never let Silvia see how much she annoyed me. And I tried not to let Helena discover how her challenges made me feel jittery. `The first time I ever saw Helena she was holding a child.'
