We were now within a week of Buenos Ayres, and had come into summer weather. When we passed the twentieth parallel the heat was overpowering. We took to ducks, and the ladies, as we could observe, to the lightest of cotton dresses. For all, however, that we saw of them they might have been dwelling in another sphere, as, indeed, they were. The steward alone had the privilege of communion with them, and he, being a distant fellow, had nothing to say, though, I believe, Lane cross-questioned him rigorously.

I have said that we saw nothing of our passengers, but I, at least, was to see them more nearly very soon, and that in the most unexpected manner. One evening I had retired to my cabin and was stretched in my bunk, reading one of the gilded books from the yacht's library, when I was interrupted by a knock on the door.

"Come in," I called idly, and the door promptly opened, and to my amazement Miss Morland stood before me. She wore a plain evening dress of chiffon, very pretty to the eye, and over her head and shoulders a mantle of silk lace. She had naturally, as I had observed on my previous encounters, a sparkle of colour in her face; but now she had lost it, and was dead white of complexion under the electric light.

"Doctor Phillimore," she said in English, which was more perfect of accent than her brother's, but speaking somewhat formally, "I understand that you believe you have discovered some plot."

By this time I was on my feet. "Madam, no one else believes it," said I.

"I do," she said sharply; and then, "I want you to come and see my brother—Mr. Morland."

"I will do as you will," I answered, "but, at the same time, I must point out that Mr. Morland has cognisance of my story. I stated what I had to say in his presence some days since."

"Ah," said she, "you do not understand. It is impossible for one in my brother's position to entertain these suspicions. It is not for him to take precautions—or should not be," she added bitterly.

I bowed. "I will repeat what I have already stated," I said; and then, as she turned to go, I took a sudden impulse. My heart was beating faster at this unexpected appearance of an ally and I made up my mind to confirm the alliance if it was what it seemed.

"Miss Morland," said I, "if I must continue to call you so."
