'Jupiter, Famia! Was that idiot a friend of yours?'

'I told him to look out for you-we're on soon!' My brother-in-law seemed to be assuming I was interested in the progress of my own cockeyed horse.

We were next. There was a shift in the atmosphere; word had it this was a race to watch. Famia said big money was riding on Ferox. The champion did look special-that high-stepping gait, the powerful build, and the deep-purple sheen on his wonderful coat. He looked like a horse who knew this was his great day. As I watched Bryon mounting their jockey, he and I exchanged a good-mannered nod. It was then that I noticed someone, someone not studying Ferox but intently scanning the crowd which was inspecting him. Someone looking for Pertinax, without a doubt. I muttered to Famia, 'Just seen a girl I know-' Then I slipped through the crowd while my brother-in-law was still grumbling how he would have thought that on this one occasion I could leave the women be…

'Tullia!'

'Falco.'

'I was looking for you yesterday.'

'I was looking for Barnabas.'

'Will you see him again?'

'Depends on his horse,' the barmaid said dourly. 'He thinks he has a winner-but he left his bets with me!'

I drew Tullia by the arm right across the Cattle Market Forum to the shade and quiet beside that little round temple with the Corinthian columns. I had never been in it or noticed who its divinity was, but its neat structure had always appealed to me. Unlike the more brash temples further from the river, this lacked the usual swarm of seedy trade and seemed an improper place to be propositioning a big-eyed young girl in her sparkly-hemmed holiday gown.

'I have something to suggest to you, Tullia.'

'If it's filthy, don't bother!' she whipped back warily.

'Had enough of men? Then how would you like to make a great deal of money for yourself?'

Tullia assured me she would like that very much. 'What money, Falco?'

If I said half a million she would not believe me. 'A lot. It should go to Barnabas. But I reckon you deserve it more…'

So did Tullia. 'How do I get it, Falco?'

I smiled quietly. Then I explained to the barmaid how she could help me corner Pertinax, and obtain for herself a fortune that was as pretty as her face.

'Yes!' she said. I love a girl who does not hesitate.

We walked back to the horses. Little Sweetheart was gazing about him as if all this was wonderful. What a comic. The first time Famia put up his jockey, my wonderful animal shrugged him straight off.

'Which one's that, Falco?' Tullia enquired.

'Little Sweetheart. He belongs to me.'

Tullia chuckled. 'Good luck, then! Oh-I'll give you these!' She handed me a leather pouch. 'His betting tokens. Why should Barnabas have the benefit? In any case,' she told me, 'he was afraid to use his own name in case it was recognized-so he used yours!'

If that was his sense of humour, I guessed that it must have been Pertinax himself who had named my horse.

Since Ferox was carrying all my spare savings, I did want to see the race. So when Titus Caesar, whom I had met previously in the course of my work, sent me an invitation to join him in the president's box, I shot up there in a trice.

It was the one place in the Circus where I knew there could be no chance of Anacrites interrupting me.

Titus Caesar was a younger, more easy-going version of his Imperial papa. He knew me well enough not to be surprised when I burst into his presence with a toga bundled under one arm instead of arrayed in the immaculate drapes most people adopted at public meetings with the Emperor's son.

'Sorry, Caesar! I was helping out with a dung shovel. They're a bit short-staffed.'

'Falco!' Like Vespasian, Titus tended to look as though he could not decide whether I was the most appalling subordinate ever to be wished on his retinue, or his best laugh today. 'My father says you're claiming Little Sweetheart is sausage meat-I reckon that makes him a certainty.'

I laughed, uneasily, as I hastily robed myself. 'Caesar, the odds against my poor bag of bones are a hundred to one!'

'Could be a killing here!' Titus winked at me happily.

I told Titus I assumed he was old enough not to bet his purple livery on a shag-tailed besom like mine. He looked thoughtful. Then the curly-haired Caesar adjusted his wreath, stood up to give the crowd someone to roar at, and solemnly let fall the white kerchief to start our race.

It was a novice sprint for five-year-olds. There were ten declared, but one refused the starting box. Until Ferox put in his late appearance on the racecard, the favourite had been a big grey Mauretanian, although other people reckoned the clever money was on a compact little black chaser with Thracian blood. (It was well sweated up, and looked like a windblower to me.) Our Ferox was a Spaniard; there could be no doubt of it. Everything from the proud set of his head to the hungry gleam in his eye spoke quality.

When the slaves hauled the ropes and the starting gates swung out in unison, the Mauretanian was already stretching his neck as the horses crossed the starting line. Ferox was close behind him. Little Sweetheart had been crowded out by a brown horse with a white sock and a spiteful squint, so he was last.

'Ah!' murmured Titus, in the tone of a man who has pledged his last tunic to his bookmaker and is wondering if his brother will lend him one. (His brother was the mean-tempered Domitian, so probably not.) 'A back marker, eh? Tactics, Falco?' I glanced at him, then grinned and settled down to watch Ferox race.

Seven laps provide a lot of opportunity for casual conversation of a knowledgeable kind. We worked our way through the fact that it was a useful field and that the grey Mauretanian was in great heart but seemed in need of an outing so might not finish a principal. White socks was running wide round the goal posts, while the little black Thracian looked a lovely horse, an easy mover with a very consistent stride.

'Generous and genuine!' boasted a guardsman who had bet on him, but the Thracian had given all he had by the third lap.

Seven circuits when your savings are in the balance seem a long time.

By the time they lifted down the fourth of the wooden eggs that count off the laps, complete silence had fallen in the president's box. It was starting to look like a two-horse race: Ferox and the Mauretanian. Ferox ran in an interested manner, cantering easily with his tail straight behind him. He had grace and he had elegance. He ran with his head up to give him a good view of any horses in front. He could run as fast as anything on the track, but quite early on I began to suspect that our beautiful mulberry stallion actually liked something to watch in front of him.

'I think yours is pulling up,' Titus suggested, hopefully trying to be polite. 'Perhaps he'll come from behind.'

I answered gravely, 'He's left himself a lot of work to do!'

Little Sweetheart was eighth instead of ninth-but only because a perky russet had made a mistake, had come down on his nose and been pulled out.

I watched mine for a moment. He was terrible. Old mustard-face ran with the most ungainly action. Even to his owner, who was trying to be charitable, that horse looked as if he had made an appointment at the abattoir before he came out. His head stayed down as if his jockey was strangling him. As he travelled forward his back legs, which were slightly out of rhythm with the front, kicked up behind at every stride and seemed to hesitate. Thank the gods he was not a hurdler. My baby would have been the kind who looks six times at every jump as he makes his approach, then hangs in the air half-way over so your heart is in your mouth.
