Two days before the inauguration of Marcus Tullius Cicero as consul of Rome, the body of a child was pulled from the River Tiber, close to the boat sheds of the republican war fleet.

Such a discovery, though tragic, would not normally have warranted the attention of a consul-elect. But there was something so grotesque about this particular corpse, and so threatening to civic peace, that the magistrate responsible for keeping order in the city, C. Octavius, sent word to Cicero asking him to come at once.

Cicero at first was reluctant to go, pleading pressure of work. As the consular candidate who had topped the poll, it fell to him, rather than his colleague, to preside over the opening session of the senate, and he was writing his inaugural address. But I knew there was more to it than that. He had an unusual squeamishness about death. Even the killing of animals in the games disturbed him, and this weakness – for alas in politics a soft heart is always perceived as a weakness – had started to be noticed. His immediate instinct was to send me in his place.

'Of course I shall go,' I replied carefully. 'But…' I let my sentence trail away.

'But?' he said sharply. 'But what? You think it will look bad?'

I held my tongue and continued transcribing his speech. The silence lengthened.

'Oh, very well,' he groaned at last. He heaved himself to his feet. 'Octavius is a dull dog, but steady enough. He wouldn't summon me unless it was important. In any case I need to clear my head.'
