We had hoped this would entail a cozy life scanning columns of neat sums on best quality parchment in rich men's luxurious studies: no such luck. I for one was known to be tough, and as an informer I was probably thought to have slightly grubby origins. So Vespasian and Titus had thwarted me by deciding that they wanted the best value for hiring Falco & Partner (the specific identity of my Partner had not been revealed, for good reasons). They ordered us to forget the easy life and to investigate the gray economy.

Hence the arena. It was thought that the trainers and suppliers were lying through their teeth-as they undoubtedly were, and so was everybody. Anyway their shifty looks had caught the attention of our imperial masters, and that was what we were probing on that seemingly ordinary morning, when we were unexpectedly invited to look at a corpse.

WORKING FOR THE Censors had been my idea. A chance conversation with the senator Camillus Verus some weeks before had alerted me that tax reassessments were being imposed. I realized that this could be properly organized, with a dedicated audit team looking into suspect cases (a category into which Camillus himself did not fall; he was just a poor coot with an unlucky face who fell foul of an assessor and who could not afford the kind of smooth accountant who might have dug him out of it).

Putting myself forward to direct the enquiries proved tricky. There were always scores of bright sparks in their best togas running up to the Palace to suggest wonderful ruses that would be the salvation of the Empire. Court officials were adept at rejecting them. For one thing, even wonderful ideas were not always welcome to Vespasian, because he was a realist. It was said that when an engineer described how the huge new columns for the restored Temple of Jupiter could be hauled up the Capitol very cheaply by mechanical means, Vespasian rejected the idea because he preferred paying the lower classes to do the job and earn themselves money to eat. Certainly the old man knew how to avoid a riot.

I did go up to the Palatine with my suggestion. I sat in an imperial salon full of other hopefuls for half a morning, but I soon grew bored. It was no good, anyway. If I wanted to make money from the Census I had to start quickly. I dared not wait in a queue for months; the Census was only supposed to take a year.

There was another problem at the Palace: my current partner was an imperial employee already. I had not wanted Anacrites to attach himself to me, but after eight hard years as a solo informer I had bowed to pressure from everyone close to me and agreed that I needed a colleague. For a few weeks I worked in harness with my best friend Petronius Longus, who had been temporarily suspended from the vigiles. I'd like to say it had been a success, though in fact his approach had been opposite from mine on virtually everything. When Petro decided to clean up his private life and was reinstated by his tribune, it had been a relief to us both.

That left me with a meager choice. Nobody wants to be an informer. Not many men have the necessary qualities of shrewdness and tenacity, or decent feet for slogging the pavements, or good contacts for supplying information-particularly information that by rights ought to be unobtainable. Among the few who qualified even fewer wanted my company, especially now Petro was trumpeting all around the Aventine that I was a picky swine to share an office with.

Anacrites and I had never been soul mates. I had disliked him on principle when he was Chief Spy at the court and I was a backstreet operator with only private clients; once I started hacking for Vespasian myself, my dislike was soon enhanced by firsthand knowledge that Anacrites was incompetent, devious, and cheap. (All these accusations are leveled at informers too, but that's just slander.) When, during a mission to Nabataea, Anacrites tried to have me murdered I stopped pretending to be tolerant.

Fate took a hand after he was attacked by a would-be assassin. It was not me; I would have made a thorough job of it. Even he knew that. Instead, when he was found unconscious with a hole in his skull, I somehow ended up persuading my own mother to look after him. For weeks his life hung in the balance, but Ma dragged him back from the shore of the Lethe using sheer determination and vegetable broth. After she had saved him I came home from a trip to Baetica to find a bond between them that was as strong as if Ma had fostered an orphaned duck. Anacrites' respect for my mother was only slightly less revolting than her reverence for him.

It was Ma's idea to foist him onto me. Believe me, the arrangement would only stay in place until I found someone else. In any case, Anacrites was officially on sick leave from his old job. That was why I could hardly appear at the Palace listing him as half my partnership: the Palace was already paying him to do nothing on account of his terrible head wound, and his superiors must not find out he was moonlighting.

Just one of those additional complications that keep life sweet.

Strictly speaking I already had one partner. She shared my problems and laughed at my mistakes; I was assisted in doing my accounts, solving puzzles, and even sometimes conducting interviews by my live-in love, Helena. If nobody took her seriously as a business associate it was partly because women have no legal identity. Besides, Helena was a senator's daughter; most people still believed she would leave me one day. Even after three years of the closest kind of friendship, after traveling abroad with me, and bearing my child, Helena Justina was still expected to grow tired of me and flee back to her former life. Her illustrious father was the same Camillus Verus who gave me the idea of working for the Censors; her noble mother, Julia Justa, would be only too happy to send a chair to fetch Helena home.

We lived as subtenants in a dire first-floor apartment on the rough side of the Aventine. We had to wash the baby at the public baths and have our baking done at a pie shop. Our dog had brought us several rats as presents, which we reckoned she had caught pretty close to home. This was why I needed decent work, with healthy incomings. The senator would be delighted that his chance remarks had given me the idea for it. He would be even more proud if he ever found out that in the end it was Helena who obtained the work for me.

"Marcus, would you like Papa to ask Vespasian to offer you work with the Censors?"

"No," I said.

"I thought not."

"You mean I'm pigheaded?"

"You like to do things for yourself," Helena replied calmly. She could be at her most insulting when she pretended to be fair.

She was a tall girl, with a strict expression and a searing glance. People who had expected me to find myself some bonny piece with lambswool where her brains should be were still surprised at my choice, but once I had met Helena Justina I reckoned on sticking with her for as long as she would have me. She was neat, scathing, intelligent, wondrously unpredictable. I still could not believe my luck that she had even noticed me, let alone that she lived in my apartment, was the mother of my baby daughter, and had taken charge of my disorganized life.

The gorgeous armful knew that she could run rings around me, and that I loved to let her do it. "Well Marcus, darling, if you won't be going back to the Palace this afternoon, could you possibly assist me with an errand on the other side of the city?"

"Of course," I agreed handsomely. Anything to put myself out of reach of Anacrites.
