"I take all proper precaution, at least. When were you vaccinated last, may I ask?"

"In Rome, in June, 1883."

"Then, with your permission, I'll do it again, and at once. You cannot be too careful."

Receiving her assent I went off to my cabin, where I had noticed that a large portion of my medical outfit had been stored, and having obtained what I sought, returned with it to the saloon. Alie, for by that name I must henceforward call her, was waiting for me, her arm bared to the shoulder. Never, if I live to be a hundred, shall I forget the impression that snow-white arm made upon me. It seemed like an act of basest sacrilege to perform even such a simple operation upon it. Beelzebub, the bulldog, evidently thought so too, for he watched me attentively enough during the whole of the time it took me. However, it had to be done, and done it accordingly was. Then, when I had put my paraphernalia back into its case, I bade her good-bye, and turned to go. She stopped me, however, and held out her hand.

"Do you know, Dr. De Normanville, I want to make you like me. I want you to forget, if you can,—while you are with us, at any rate,—the stories you have heard about me. Some day, perhaps, I will attempt to show you that I am not altogether as bad as people have painted me."

For the moment I was so completely carried away by her outburst of girlish frankness that I hardly knew what to say.

"'Pon my soul, I really don't believe you are!" I blurted out, like a schoolboy.

"Thank you for that, at least," she said, smiling at my earnestness; and then, making me a little curtsey, she turned and disappeared through the door by which she had first entered the saloon.

Putting my case into my pocket, I looked round the room once more, and then went up on deck, not knowing what to think. It seemed impossible to believe that this frank, beautiful girl, whose eyes were so steady and true, whose voice had such a genuine, hearty ring in it, could be the notorious criminal of whom all the East was talking. And yet without a shadow of a doubt it was so. And if it came to that, what was I, staid, respectable George De Normanville, doing, but aiding and abetting her in her nefarious career? True, I might salve my conscience with the knowledge that I had been drawn into it unconsciously, and was only acting in the interests of humanity, but it was nevertheless a fact, and one that I could not have disputed if I had wanted to, that I was the paid servant of the Beautiful White Devil.

It was just two bells in the first dog watch when I came on deck, and hard upon sundown. The great round sun, which had been so busy all day long, now rested in a bed of opal cloud scarcely a hand's breadth above the edge of the horizon. The breeze had moderated, since midday, and now the water around us was almost without a ripple, but glorified with flakes and blotches of almost every colour known to man. Near at hand it was a mixture of lemon and silver, a little further almost a lilac-purple, further still a touch of pale heliotrope meeting salmon-pink and old gold, while under the sun itself a blotch of red, fierce as a clot of blood, worked through the cloud till it got back to gold, then to salmon-pink, then through purple up again to the lemon and silver sky. It was a wonderful sunset, and a fitting termination to an extraordinary day.
