I saw Laeta first, my preference. He did not turn me away. His method was to greet you with interest, listen gravely—then if your story was unwelcome politically, he let you down without a qualm. Unsurprisingly, he let me down.

‘It’s too thin. On what you’ve got, Falco, I don’t see this going anywhere. Anacrites will simply say he made a mistake when he employed those men, and thank you for pointing it out to him.’

‘Then he’ll get me for it.’

‘Of course. What do you expect with his background?’

‘What does that mean?’ I raised an eyebrow. ‘As far as I know, his background is the same as yours. An imperial slave who made good—in his case, for unfathomable reasons.’

‘He is bright,’ Laeta said tersely.

‘I’ve known pavement sweepers who could think and talk and grade dog turds to a system as they collected them—but such men don’t end up in senior positions.’

‘Anacrites was always known for his intellect—though he was more physical than most secretaries, which suits his calling. He had pliability; he could bend with the political breeze—which, when he and I were coming up the staff list, was a must!’

‘He adapted himself to the quirks of emperors, whether mad, half-mad, drunkard or plain incompetent?’

‘Still at it. Titus thinks well of him.’

‘But you don’t. You have a singer spying on him at home,’ I threw in.

Laeta brushed it aside. ‘The same man who observes me for Anacrites! Suspicion is a game we all play. Nevertheless, Marcus Didius, if you find genuine proof of corruption, I am sure I can persuade the old man to act on it.’

‘Well, thanks! Tell me what you meant about the spy’s background,’ I persisted.

Laeta gave me a fond shake of the head—but then what he said was enlightening: ‘Many of us feel he never fitted in. You compared him with me—but my grandmother was a favourite of the Empress Livia; I have respected brothers and cousins in the secretariats. Anacrites came up the ladder by himself, always a loner. It gave him an edge, honed his ambition—but he never shakes off his isolation.’

‘Not isolated enough for me; he crushes up against me and my family.’

Laeta laughed softly. ‘I wonder why?’ He went no further, naturally. ‘So, Falco, dare I ask: are you and your cronies still investigating the Pontine Marsh murders?’

I gave him a straight look. ‘How can we, when our last instructions were to drop the case? Instructions, Claudius Laeta, which you gave us!’

He laughed again. I smiled with him as a courtesy. But as soon as I left, I stopped smiling.
