"These papers," he said, "are in perfect order. But they do not prove that you are the men named in them though they incline me to believe it. I should believe it, but these men deny that you are Bruttius Asper and Sabinus Felix." "And why do they deny it?" Agathemer queried triumphantly. "Why, because they were caught by this busybody and asked whether they knew Bruttius Asper and Sabinus Felix and they said they did; then haled in here by him and confronted with us and asked whether they knew us and of course said they did not, as they did not. And why do they not know us? Because they are not couriers at all, but men passing themselves off as couriers. Our papers are in perfect order, as you say. Ask them for their papers. They haven't any!" By the faces of the two I saw that Agathemer had guessed right. They, in fact, were impostors. They had no despatches, no credentials, no papers at all, except a diploma with entries from Bononia, through Parma, Placentia and Clastidium to Dertona and so onwards; a diploma so manifestly a clumsy forgery that, at sight of it, I wondered how it had fooled the stupidest change-master. Pescennius barely glanced at it. To his apparitors, he said: "Arrest these three!" In a trice Donnotaurus and the two impostors were seized. To us he said: "Gentlemen, I apologize for having doubted you, even for a moment. And I thank you for having so cleverly and quietly exposed these precious gentry. I shall keep an eye on them and on this local meddler; I'll investigate them in Marseilles. "Meantime I must eat. So I'll remain here. You are in haste and you have eaten. Your horses are ready. I need not detain you. I'll see you at Marseilles tomorrow. I congratulate you on your horsemanship. To have overtaken me, even when I am travelling by carriage, is no mean exploit. I am pleased to have made your acquaintance." And he bade us farewell, allowed us to pass out, and seated himself at our table. CHAPTER XIX MARSEILLES AND TIBER WHARF We rode the first mile at full gallop and then slowed to an easy canter which permitted of conversation. All the way to Calcaria we discussed our situation, prospects and plans. We revised our previous view and agreed that we had best not be too late entering Marseilles, as we might not have time to buy cloaks, hats and footgear, change and get rid of our equipment and find lodgings. Then again, of course, we fell into a panic at the idea of riding into Couriers' Headquarters and perhaps facing a dozen men who knew Sabinus Felix and Bruttius Asper as well as we knew each other. We went over, for the tenth time, a series of absurd suggestions and tried to conceive some way by which we might sneak in at some other gate than that to which our road led, might avoid delivering our despatches and might find ourselves safe in ordinary clothes in some obscure lodging.
