‘Thank you.’ Alberti put on a pair of eyeglasses and took Giovanni’s letter to the light of the candle burning on his desk. There was no sound in the room apart from the ticking of the clock and the occasional soft crash as the embers of the fire collapsed on themselves. If there was another presence in the room, Ezio had forgotten it.

Alberti now turned his attention to the documents. He took some time over them, and finally placed one of them discreetly inside his black doublet. The others he put carefully to one side, apart from the other papers on his desk.

‘There’s been a terrible misunderstanding, my dear Ezio,’ he said, taking off his spectacles. ‘It’s true that allegations were laid – serious allegations – and that a trial has been scheduled for tomorrow morning. But it seems that someone may have been, perhaps for reasons of their own, overly zealous. But don’t worry. I’ll clear everything up.’

Ezio hardly dared to believe him. ‘How?’

‘The documents you’ve given me contain evidence of a conspiracy against your father and against the city. I’ll present these papers at the hearing in the morning, and Giovanni and your brothers will be released. I guarantee it.’

Relief flooded through the young man. He clasped the Gonfaloniere’s hand. ‘How can I thank you?’

‘The administration of justice is my job, Ezio. I take it very seriously, and ‘ for a fraction of a second he hesitated, ‘ your father is one of my dearest friends.’ Alberti smiled. ‘But where are my manners? I haven’t even offered you a glass of wine.’ He paused. ‘And where will you spend the night? I still have some urgent business to attend to, but my servants will see that you have food and drink and a warm bed.’

At the time, Ezio didn’t know why he refused so kind an offer.

It was well after midnight by the time he left the Gonfaloniere’s mansion. Pulling up his hood again, he prowled through the streets trying to arrange his thoughts. Presently, he knew where his feet were taking him.

Once there, he climbed to the balcony with greater ease than he’d imagined possible – perhaps urgency lent strength to his muscles – and knocked gently on her shutters, calling quietly, ‘Cristina! Amore! Wake up! It’s me.’ He waited, silent as a cat, and listened. He could hear her stirring, rising. And then her voice, scared, on the other side of the shutters.

‘Who is it?’

‘Ezio.’

She opened the shutters swiftly. ‘What is it? What’s wrong?’

‘Let me come in. Please.’

Sitting on her bed, he told her the whole story.

‘I knew something was amiss,’ she said. ‘My father seemed troubled this evening. But it does sound as if all will be well.’

‘I need you to let me stay here tonight – don’t worry, I’ll be gone long before dawn – and I need to leave something with you for safekeeping.’ He unslung his pouch and placed it between them. ‘I must trust you.’

‘Oh, Ezio, of course you can.’

He fell into a troubled sleep, in her arms.

It was a grey and overcast morning – and the city felt oppressed with the muggy heat that was trapped by the overhanging cloud. Ezio arrived at the Piazza della Signoria and saw, to his intense surprise, that a dense crowd had gathered already. A platform had been erected, and on it was placed a table covered with a heavy brocade cloth bearing the arms of the city. Standing behind it were Uberto Alberti and a tall, powerfully built man with a beaky nose and careful, calculating eyes, dressed in robes of rich crimson – a stranger to Ezio, at least. But his attention was caught by the sight of the other occupants of the platform – his father, and his brothers, all in chains; and just beyond them stood a tall construction with a heavy crossbeam from which three nooses were suspended.

Ezio had arrived at the piazza in a mood of anxious optimism – had not the Gonfaloniere told him that all would be resolved this day? Now his feelings changed. Something was wrong – badly wrong. He tried to push his way forward, but could not press through the mob – he felt the claustrophobia threaten to overwhelm him. Desperately trying to calm down, to rationalise his actions, he paused, drew his hood close over his head, and adjusted the sword at his belt. Surely Alberti would not let him down? And all the time he noticed that the tall man, a Spaniard by his dress, his face and his complexion, was ranging the mass of people with those piercing eyes. Who was he? Why did he stir something in Ezio’s memory? Had he seen him somewhere before?

The Gonfaloniere, resplendent in his robes of office, raised his arms to quieten the people, and instantly a hush fell over them.

‘Giovanni Auditore,’ said Alberti in a commanding tone which failed, to Ezio’s acute ear, to conceal a note of fear. ‘You and your accomplices stand accused of the crime of treason. Have you any evidence to counter this charge?’

Giovanni looked at once surprised and uneasy. ‘Yes, you have it all in the documents that were delivered to you last night.’

But Alberti said, ‘I know of no such documents, Auditore.’

Ezio saw at once that this was a show-trial, but he couldn’t understand what looked like deep treachery on Alberti’s part. He shouted, ‘It’s a lie!’ But his voice was drowned by the roar of the crowd. He struggled to get closer, shoving angry citizens aside, but there were too many of them, and he was trapped in their midst.

Alberti was speaking again: ‘The evidence against you has been amassed and examined. It is irrefutable. In the absence of any proof to the contrary, I am bound by my office to pronounce you and your accomplices, Federico and Petruccio, and – in absentia – your son Ezio – guilty of the crime you stand accused of.’ He paused as the crowd once more fell silent. ‘I hereby sentence you all to death, the sentence to be carried out immediately!’

The crowd roared again. At a signal from Alberti, the hangman prepared the nooses, while two of his assistants took first little Petruccio, who was fighting back tears, to the gallows. The rope was placed round his neck as he prayed rapidly and the attendant priest shook Holy Water on to his head. Then the executioner pulled a lever set into the scaffold, and the boy dangled, kicking the air until he was still. ‘No!’ mouthed Ezio, barely able to believe what he was seeing. ‘No, God, please no!’ But his words were choked in his throat, his loss overcoming all.

Federico was next, bellowing his innocence and that of his family, struggling in vain to break loose from the guards who wrestled him towards the gallows. Ezio, now beside himself, striving desperately forward again, saw a solitary tear roll down his father’s ashen cheek. Aghast, Ezio watched as his older brother and greatest friend jolted at the rope’s end – it took longer for him to leave the world than it had taken Petruccio, but at last he, too, was still, swaying from the gallows – you could hear the wooden crossbeam creak in the silence. Ezio fought with the disbelief within him – could this really be happening?
