asked.
    Luca shook his head. ‘Who got to it?’
    ‘Arabs, Moors, Ottomans, call them what you will. Mussulmen, Muslim-men, infidels, our enemies, our new conquerors. Do you know how they got that sign?’
    ‘No.’
    ‘It is the shape left by a counter in the sand when you have taken the counter away. It is the symbol for nothing, it looks like a nothing. It is what it symbolises. That is how they think. That is what we have to learn from them.’
    ‘I don’t understand. What do we have to learn?’
    ‘To look, and look, and look. That is what they do. They look at everything, they think about everything, that is why they have seen stars in the sky that we have never seen. That is why they make physic from plants that we have never noticed.’ He pulled his hood closer, so that his face was completely shadowed. ‘That is why they will defeat us unless we learn to see like they see, to think like they think, to count like they count. Perhaps a young man like you can learn their language too.’
    Luca could not take his eyes from the paper where the man had marked out ten spaces of counting, down to zero and then beyond.
    ‘So, what do you think?’ the Inquisitor asked him. ‘Do you think ten nothings are beings of the unseen world? Like ten invisible things? Ten ghosts? Ten angels?’
    ‘If you could calculate beyond nothing,’ Luca started, ‘you could show what you had lost. Say someone was a merchant, and his debt in one country, or on one voyage, was greater than his fortune, you could show exactly how much his debt was. You could show his loss. You could show how much less than nothing he had, how much he would have to earn before he had something again.’
    ‘Yes,’ the man said. ‘With zero you can measure what is not there. The Ottomans took Constantinople and our empire in the east not only because they had the strongest armies and the best commanders, but because they had a weapon that we did not have: a cannon so massive that it took sixty oxen to pull it into place. They have knowledge of things that we don’t understand. The reason that I sent for you, the reason that you were expelled from your monastery but not punished there for disobedience or tortured for heresy, is that I want you to learn these mysteries; I want you to explore them, so that we can know them, and arm ourselves against them.’
    ‘Is zero one of the things I must study? Will I go to the Ottomans and learn from them? Will I learn about their studies?’
    The man laughed and pushed the piece of paper with the Arabic numerals towards the novice priest, holding it with one finger on the page. ‘I will let you have this,’ he promised. ‘It can be your reward when you have worked to my satisfaction and set out on your mission. And yes, perhaps you will go to the infidel and live among them and learn their ways. But for now, you have to swear obedience to me and to our Order. I will send you out to be my ears and eyes. I will send you to hunt for mysteries, to find knowledge. I will send you to map fears, to seek darkness in all its shapes and forms. I will send you out to understand things, to be part of our Order that seeks to understand everything.’
    He could see Luca’s face light up at the thought of a life devoted to inquiry. But then the young man hesitated. ‘I won’t know what to do,’ Luca confessed. ‘I wouldn’t know where to begin. I understand nothing! How will I know where to go or what to do?’
    ‘I am going to send you to be trained. I will send you to study with masters. They will teach you the law, and what powers you have to convene a court or an inquiry. You will learn what to look for and how to question someone. You will understand when someone must be released to earthly powers – the mayors of towns or the lords of the manor; or when they can be punished by the Church. You will learn when to forgive and when to punish. When you are ready, when you have been trained, I will send you on your
