‘That’s a treasonous question.’
‘But it’s a pertinent one. If Claudius does die soon, Britannicus will be moved aside and Nero will become emperor having married his stepsister who is also his first cousin once removed; it’s not quite Egyptian but it’s getting close. How long can a bloodline like that last? Suppose it finishes with Nero, what then?’
‘Then the Guard will proclaim an emperor.’
‘That only works if there is a suitable candidate from the imperial family. But each province with legions will want their own generals, because if they support a man to the Purple they know they’ll be very well rewarded.’
‘Civil war, you mean?’
‘Of course. And there’re no rules about what blood a man needs running in his veins in order to win a civil war; he just needs to ensure that it stays in them.’
Gaius turned his hooded face towards Vespasian, his voice conveying his consternation. ‘You, dear boy?’
‘Why not? Sabinus was at my naming ceremony; he saw the auspices but has always refused to talk about it because of the oath. However, he asked me, after Claudius had taken back the sword, what if Antonia had not given it to me as a simple gift but had actually given it to the person that she thought would make the best emperor, as she had always said she would? And at that moment I thought: Why not? Why not me? Because someday it will be someone from a different family; it has to be if Rome is to survive. Tiberius, Caligula, Claudius? If Nero is like any one of them then …’ Vespasian trailed off; the point did not need to be made.
‘You think that Sabinus believes you could become …?’ It was Gaius’ turn to leave a question hanging.
‘I’m not saying that; all I’m saying is that he put it into my mind. And I think that Pallas also has a suspicion; I think Antonia said something to both him and Caenis when she gave them her father’s sword to pass on to me before she died, but I’m willing to bet that she swore them to secrecy. But I think that Pallas managing to help me to a position which is obviously so fraught with danger that Agrippina does not expect me to survive is his way of testing whether Antonia was right.’
‘You mean if you survive you’ll eventually become …?’ Gaius tried but again failed to complete the sentence.
‘I expect that if I survive Pallas might look at me in a different light.’
‘You don’t seriously think that you could be the …?’
‘Why not, Uncle? Look at me: look at how far I’ve come since being brought to your house when I was sixteen with lofty ideals of serving Rome for the greater good. I’m now consul, admittedly only for two months, but I’ve reached that rank because of what I’ve achieved and not because of what blood flows in my veins. I’ve commanded a legion in the field for six years, four of those in Britannia against some very unpleasant tribes; I’ve spilt blood when necessary and sometimes when not. Here, in Rome, I know how the politics of the city and of the palace work because for years now I’ve been unwillingly wading through their mire; I’ve become just as ruthless as the practitioners whom I’ve learnt from and whom I’ve come to admire. I understand the power of money, fear and patronage and know that any man can be bought by a mixture of all three; it’s just a question of finding the right levels of each ingredient. I’m ideally qualified.’
Gaius’ jowls quivered with fear. ‘You can’t believe that you’ll succeed to the …?’
‘No, Uncle; but I may fight my way there one day. If the blood of the Caesars fails there’ll be a scramble for the Purple and who better than someone like me? But if it’s to be someone like me then why not me?’
‘And you think all this just because of a mark that looks like a “V” on a liver?’
‘Not just that. I think this because then many things, strange things, that have happened in my life start to make sense: the Phoenix, the prophecy of Amphiaraios, Myrddin, the Oracle of Amun telling me that I had come before it too early to know the right question to ask; every weird thing that has happened to me would be explained by that.’
‘This is something that you should keep to yourself, dear boy; it won’t do to go about shouting that you’re a potential …’ Gaius still could not bring himself to say the word.
‘Oh, I will keep it to myself, Uncle. And I won’t dare to believe that I’m right until it happens. However, because I know the possibility is now there I shall watch out for sensible opportunities and will not do anything rash in the meantime.’
