“No doubt,” I returned grimly. “But that’s scarcely the point just now, is it? You can leave me to deal with them—‘friends’ as you call them—or foes. What, dearest, I want to hear from you is this”—and I smiled into her eyes—“On what mad pretext were you lured here? How did you, of all the sweet and helpful souls on God’s earth, come to learn that I had been kidnapped—”
“Father told me,” she replied, with a blush—and she bent her head.
“Colonel Napier! Your father told you,” I ejaculated. “But how in the name of fate did he come to be mixed up in this affair, which may end anywhere—even an assize court.”
“Lord Fotheringay came and had a private chat with him in our flat at Whitehall Court,” she explained. “That was about half-an-hour ago. I don’t know, of course, what passed between them, but suddenly father came to me and said that you were in great danger and had been rescued by Mr Zouche’s cleverness and the earl’s quickness. He added, too, that somehow you had mixed yourself up in some terrible conspiracy which he had promised the earl, when he told him about it in confidence, that he would not reveal to a soul, but that I might, if I cared for you as much as ever, and did really wish to help you, take a hansom here and release you from this cellar and tell you from him that, whatever you do, you must instantly drop all connection with some man he called José Casteno?”
“Thanks, but that’s not enough,” I answered hotly. “The truth is, I’ve undertaken certain work for Casteno, and I shall carry it through. Believe me that, after all has been said and explained, it is Colonel Napier who has been made a puppet and not myself.”
“Yes,” I went on; “I mean Lord Fotheringay and Peter Zouche,” and I saw the girl start and her face blanch. “Bah! you can never know what they have dared to do to me.” And in a few graphic but incisive sentences I recounted to her all my humiliating and baffling experiences in the mart that afternoon.
“But perhaps,” suggested Doris timidly when I had finished my passionate outburst, “they did not mean anything unkind to you after all. Look at the affair outside yourself. Perhaps great issues hang on the recovery of those three old manuscripts, and it is really you who are, as they assert, being made a tool of—to ruin them.”
“I don’t care whether I am or not.” I retorted savagely, pulling my hat tightly across my temples. “I have seen Casteno, and I, who am usually reputed a fine judge of character by voice and face, like him, and I shall not cease my association with him until I prove conclusively that he is not worthy of my trust or assistance.
“Besides, Doris,” I went on earnestly, “this particular commission of his means everything that I really value in life—it means you! Don’t you recollect, as keenly as I do, how the colonel has forbidden us to be formally engaged until I can point to at least a thousand pounds, which I can tell him truthfully that I have made out of this new fantastic profession of mine as a secret investigator? Well, listen to me. If all goes well I see my way now quite easily to make this amount out of Casteno alone. Already he has handed me seven hundred and fifty pounds, and I can quickly run out other work on his behalf amounting to that extra two fifty. As for Lord Fotheringay, he’ll never be of any professional use to me. Ever since he got back from America he’s been quite a different man to all of us who were his old friends. Something dreadful must have happened to him there. He’s changed hideously for the worse.”
And then I stopped suddenly. This casual reference to America recalled something to me (like casual references often do to all of us) that I had quite forgotten. It was nothing less than a connection with America which both Lord Fotheringay and the dead priest, Father Alphonse Calasanctius, had in common. Could it—I now asked myself—could it really happen that Don José Casteno had also come from that same South American Republic—the Republic of Mexico? And could those faded parchment rolls relate to some secret which the Earl of Fotheringay had discovered whilst he was in Mexico, and in regard to which he had procured the assistance of Zouche, one of the finest, most noted palaeographists and experts in mediaeval cypher that the British Museum has ever employed?
