I thought again of Felix’s pudgy face. ‘That man would not willingly trust his own reflection in a mirror, unless he held it firmly by the neck. He must have had some additional hold on Zetso — or perhaps Zetso had a hold on him.’ I moved aside the cord, taking care not to disturb the seal — I might need that later, if I was called to account for my actions — and opened the latch on the writing tablet. Junio held the candle closer.
The message was short, scratched out in a bold but uneducated hand. ‘We are too late. The man is dead. Send word to Glevum. I ride to warn the rest.’
‘So!’ Junio said eagerly. ‘You have it in your hands, master. Conclusive proof that there was a conspiracy. Zetso may not have killed his master, but he certainly planned to.’
‘This message certainly puts a new complexion on the matter, Junio, though I confess I still do not altogether understand it. However, on one point I have been peculiarly stupid. I should have noticed the seal. Go quickly now and find the octio. We will have need of his soldiers after all.’
Junio gave me another startled look and disappeared again, while I tried rather ineffectually to rouse myself by rinsing my face and neck in a bowl of water which my slave had set in readiness the night before. If I was right I needed my wits about me, and I was beginning to regret the several goblets of spiced mead that I had allowed myself the night before.
We were none too soon in reaching the octio. Soldiers keep early hours. The contingent was already afoot and preparing for the day’s march.
The octio came in, his natural air of assertive bustle restored now that Zetso had left us. He was ready to be obliging, though — I still held Marcus’s warrant in my pouch. ‘How can I assist you, citizen?’
I outlined what I wanted, and the affability flowed out of him like dye from an octopus. A little of his confidence went with it. ‘Citizen, I already have my orders. This is impossible. We could escort you to Letocetum if you wished it — but to arrest that horseman again, with that warrant still in his pocket? And then abandon our march and return with him to Glevum? That is more than my life is worth.’
I could hardly blame him for this. He was speaking literally, if a charge of disobeying orders was proved against him. He was not even a centurion, only a second-in-command. If I was wrong in my deductions I was risking not only my life, but his. And, although he did not know it, I was about to flout the Emperor’s own warrant. My only hope lay in an appeal to rank.
‘Listen, octio,’ I said, with as much authority as I could muster, ‘Helvius Pertinax is governor of this island. Every soldier in it is under his command. I issue you this order in the name of Pertinax, on the authority of the seal I hold.’ I held up the wax tablet. ‘I assure you it has more authenticity than this one.’
He glanced at the little recess on the tablet-cover where Felix’s seal still nestled on its broken cord, and his jaw dropped — for all the world like a mime at a banquet caricaturing surprise. For once I had occasion to bless the ugly Roman’s taste for ostentation. One could almost see the octio’s brain working. I could not have cut an impressive figure at that moment, in my tousled tunic with pieces of bed-straw still adhering to me — but if I had the authority to unseal that tablet, and boast of it in front of witnesses, I must be more important than he thought.
I said, to encourage him, ‘I have doubts about that warrant he was carrying, too.’
He ran a thoughtful tongue around his lips. ‘Of course, citizen, when you put it that way. . But surely, by the time we get to Letocetum, the man may easily have gone? He is an excellent rider, and he has a night’s advantage on us, and in any case my men are on foot.’
He was right, of course, and I acknowledged that. ‘Nevertheless, it is my guess that he will stay there for a while. He speaks of “others” in that tablet — it will take him a little time to find them all.’
The octio looked doubtfully at the unsealed tablet again. ‘But, citizen, even if he is still in the vicinity, how will you know where to look? Letocetum is not a large settlement but it is far bigger than this. There was most of a legion stationed there at one time, and a whole little vicus grew up around it. Besides, Letocetum is a meeting of the ways. If he has left, how will you know whether he went to Deva, Danum or Londinium?’
He was right, again. The fellow had more knowledge of the roads than I did. ‘There is a good chance that he will not have left,’ I said, with more certainty than I felt. ‘He does not expect to be followed. Once he has found his contacts, there is no need for hurry. And as for finding him in the village, that should not be difficult. Zetso spoke of Egobarbus bursting in on a meeting “in the house”. Glevum is a large colonia, but any inhabitant could tell you everywhere that Felix visited. He was not an inconspicuous person. I imagine in a small village, even on a crossroads, such information should be easy to obtain.’
The octio swallowed and nodded. He was clearly very unhappy. ‘In a while then. I must see my men are fed, and then we shall be on the road. Your servant, citizen.’ He went out, looking like a religious prisoner on the way to the arena.
I too had breakfast to attend to, although here it would be a miserable Roman affair of bread and water, with an apple if one was lucky. Oatcakes are a Celtic taste. I could find it in my heart to envy the soldiers their morning issue of thin, watery vegetable soup — the army, at least, recognises that a man must eat before he marches.
I was swallowing my crust of bread (no apples), and hoping that the taxman would not waken and join me, when the octio burst in on me again.
‘Apologies, citizen,’ he blurted, looking askance at Junio who was scrambling to his feet from my side with his mouth full of breadcrumbs, ‘but I have a solution. You could send ahead to Letocetum — there is a postrider newly arrived from Isca, with urgent orders for the garrison there. He will pause only to eat and to exchange his horse, and — although it is irregular — no doubt he could alert the garrison of your wishes. There is still a small vexillation posted there, in case of any repeat of that regrettable Boudicca affair.’
He was so delighted with his solution, which would relieve him of the necessity of arresting Zetso, that he forgot I was a Celt and that for me the ill-fated revolt of the fearless queen of the Iceni was less regrettable than tragic. However, I did not dwell on that. I had the courier sent for, and gave him instructions for the commander of the little holding garrison at Letocetum. On the assumed authority of Pertinax, naturally. All the gods preserve me, if I was wrong.
‘The fellow claims to be holding a warrant,’ I said. ‘But I believe that the seal is worthless. He is to be arrested and held until I arrive with the guard, and then I will take him back to Glevum to face trial. I believe he poisoned one of my countrymen, and perhaps conspired to kill his master besides, although I cannot prove it at the moment.’
It was all one to the courier; he was not required to arrest Zetso himself. He repeated my message faithfully, word for word, and assured me that it would be delivered to the vicus before noon. With a little help from the Fates, he added, that should ensure that Zetso was captured and waiting for me when I arrived in the evening. If he thought it odd in any way, taking these outrageous orders from an elderly civilian in a tunic, he did not betray it by so much as the flicker of an eyelid.
After he had departed, I finished my meagre breakfast and we were ready to depart ourselves. It was a slower business, moving in concert with the marching soldiers, but for a man of my mature years it was a good deal more comfortable. It was amusing too, bowling through little hamlets with an armed escort — more than one labourer, under the impression that I was some important personage, stopped to throw leaves of tribute under our wheels and half prostrate himself as I passed.
