I need not say how earnestly I studied the papers until I had mastered every detail of the case. I was, in fact, so absorbed in the work, and gave so many hours to it, that Mrs. Curwen at length protested her regret at having handed me the documents at all. I assured her, however, that it was fortunate I had read them as I was able of my own private knowledge to say there was a flaw in the title, but that I might be able to make arrangements when we reached Madrid by which matters could be put right. My idea was that the work of developing the mine might after all be done by means of her money, but that the advantage should be reaped, not by Quesada, but by Sarita and her brother; and I resolved to tackle the Minister as soon as practicable after my arrival in Madrid. As we drew nearer to our destination, the possible embarrassments of Mrs. Curwen’s and Mercy’s presence in Madrid began to bulk more largely in my thoughts. The first few days after my return were sure to find me deeply engrossed by the work I had to do, and I did not care to explain this to either of them. As soon as I knew for certain the time of our arrival, therefore, I wired to Mayhew to meet us. I was glad to find him on the platform when our special drew up, and we all went off together to the hotel, where rooms had been reserved by Mrs. Curwen. A few words explained the situation to Mayhew, who was glad enough to take charge of my companions. "If anyone knows his Madrid, it’s Mayhew," said I. "And he’s a first-class pilot. My duties to the Embassy will be rather heavy for a few days, so you won’t see much of me." I was glad that Mrs. Curwen was very favourably impressed by my friend, and as he was keen for London news, and she and Mercy were eager for Madrid gossip, the evening passed very brightly. As Mayhew and I walked to my rooms later, he was rather enthusiastic in the widow’s praises. "She’s a good sort, Silas, a real good sort—bright, cheery, and chippy," I said, "But keep off spoons; or, at least, don’t show ’em. She’s beastly rich, and, like all rich folks, thinks everybody’s after the dollars. Treat her like any other unimportant woman, show her a bit of a cold shoulder now and then, contradict her, and make her go your way and not her own, put her in the wrong occasionally and make her feel it, don’t keep all the appointments you make, and pay more attention to Mercy sometimes than you do to her—in fact, be natural and don’t make yourself cheap, and—well, you’ll save me a lot of trouble and be always sure of a welcome from her." "You seem to know a lot about her," he said, drily. "She’s my sister’s chum, Si, and I don’t want to be on duty for some days at any rate;" and I plumed myself on having given him some excellent advice and started a pretty little scheme for the mutual advantage of them both.
