"I suppose there’s nothing really serious in this Carlist business?" I said, in a tone of indifference. "You newspaper gentlemen generally know these things." "From our point of view you may call it serious, perhaps; seeing that we are ordered to such a place as Daroca. The authorities too are pretty much in earnest." "Ah, yes, so it appeared at Madrid. By the way, I saw on the station there, the great police agent, Rubio, I think his name is. He is travelling in this very train; I suppose also on Carlist business." "Rubio in this train, is he?" exclaimed Cabrera. "We must get hold of him, Garcia, and see what he’s after. He’ll have news;" and both were evidently surprised and somewhat uneasy. "I suppose you know all these officials by sight?" said I, with a light laugh. "That’s the best of newspaper work; at least so it seems to me." "We have not been long enough in the work to know many people, and we are scarcely known by anyone." "Then I am more fortunate than you, perhaps, for this Senor Rubio and I have met, and I daresay he would know me again." They were quick enough to read this as a caution that Rubio must not see me; and then I turned the talk to general matters, and one or two other passengers joined in it. At the next station, the last we were to stop at before we alighted, our fellow passengers got out. Our tickets were examined again; we were once more questioned, and the two Carlists produced credentials from their supposed newspapers, which proved sufficiently satisfactory. But when the matter had just ended and the official was closing the carriage door, an incident occurred that gave me a passing twinge of anxiety. The police agent, Rubio, passed the carriage, and a quick little start as his keen gaze flashed through the carriage showed me that he had recognised me. "Rubio has seen and recognised me," I whispered hurriedly to my companions, in a sharp authoritative manner. "He may arrest me. In that case do nothing, but go on to Daroca, and make it your chief charge to find and protect, with your lives if need be, the Senorita Sarita Castelar. I can get out of Ruble’s clutches again quite safely." "They shan’t take you," said Cabrera, with grim earnestness. "You will do nothing to prevent it. I can protect myself," and opening my sample case, I began fingering the samples again while I waited during three minutes of as anxious suspense as I have ever endured. Then to my intense relief the train started, and I breathed freely. It was moving along the platform when a young man, protesting excitedly that he must go, opened the door, jumped in and sank breathless in the corner seat, while the porter, swearing generously, ran alongside and fastened the door after him.
